When the electrons exit the channels they are further accelerated by a constant high voltage (5-6 kV) and strike the phosphor coating on the fluorescent screen causing it to release photons. Because of the MCP gain, there are now many photons for each photon that struck the photocathode surface.
WARNINGS! If the PI-MAX4 camera system is used in a manner not specified by Teledyne Princeton Instruments, the protection provided by the equipment may be impaired. 2. If the equipment is damaged, the protective grounding could be disconnected.
® PI-MAX 4 Camera System Issue 10 1.4.1 Intensifier Modes and Safety WinX Applications The Experiment Setup Main screen in WinX applications allows you to select one of two intensifier modes: Gate Mode or Safe Mode. In Gate Mode, the photocathode is biased on only for the time that each gate pulse is applied.
Chapter 1 Introduction 1.4.3 High Intensity Light Damage When biased ON, intensified CCD cameras (e.g., PI-MAX4,) can be irreparably damaged if continuously exposed to light levels greater than twice the A/D saturation level. Therefore, it is critical that conditions not be created which could result in damage to the intensifier.

Chapter 5 Gate Mode Operation 5.6.1.1 Exposure Timing Exposure is controlled by the gate width setting and the number of gates per frame. The total exposure time is the product of gate width and number of gates per frame. The time of the opening of the gate is controlled by the delay (i.e., time from trigger to optical opening.) This is set in WinX or LF.
® PI-MAX 4 Camera System Issue 10 Background Subtraction Each CCD has its own dark charge pattern or background that can be subtracted from the total acquired signal. By subtracting this background, you can eliminate the dark charge, which might otherwise hide low-intensity signal. When setting up for background subtraction, set up the experiment conditions for acquiring the actual image (i.e., camera temperature, gating sequences, region of interest, timing mode, etc.,) and then, while blocking the incoming signal from the...

Figure 5-7 shows the situation early in the readout cycle. The charge in the imaging areas has been transferred to the adjacent masked areas and up- shifting to the readout register has started.
Chapter 5 Gate Mode Operation Figure 5-8: Step 3: Non-Overlapped, Transfer to Output Node 3 Charge from first pixel has been shifted to the Output Node. Figure 5-9 illustrates the end of the readout. Both the imaging and storage areas are empty. When the intensifier is gated on again, signal charge will again be accumulated.
® PI-MAX 4 Camera System Issue 10 5.8.2 Full-Frame CCD Readout The following PI-MAX4 cameras use a full-frame architecture CCDs for data acquisition: • PI-MAX4: 1024f; • PI-MAX4: 2048f; • PI-MAX4:1024x256. Figure 5-10 illustrates the various stages of this process. Step 1 in Figure 5-10 represents a CCD immediately after exposure but before the beginning of readout.
Chapter 5 Gate Mode Operation After the accumulated charge has been shifted out of each pixel, the remaining charge is zero, meaning that the array is immediately ready for the next exposure. The equations that determine the rate at which the CCD can be read are described below.
® PI-MAX 4 Camera System Issue 10 Limitations of hardware binning include: • Lowered resolution because charge from adjacent pixels is summed into a super pixel. • Increased possibility to blooming. Because shift register pixels typically hold only twice as much charge as image pixels, the binning of large sections may result in saturation and spilling of charge back into the image area •...

Chapter 5 Gate Mode Operation • Intensifier Gain The Intensifier gain setting provides continuous adjustment over a range of 1 to 100. Gain is approximately proportional to the number entered: — 100 corresponds to the maximum gain, or 100%; — 1 corresponds to approximately 1% of the maximum gain. The default value will provide good results in many applications.
® PI-MAX 4 Camera System Issue 10 With the exception of Fast Mode/Safe Mode, which is described in full, the following paragraphs briefly describe these timing parameters. The settings appropriate to the intensifier mode and selected pulser are discussed in Chapter 6, LightField and Gated Operation.

Chapter 6: LightField and Gated Operation This chapter discusses gated operation with the SuperSYNCHRO™ timing generator as well as aspects of PI-MAX4 operation that are not covered in Chapter 4, First Light. Chapter 15, Tips and Tricks, should also be reviewed since it provides helpful information about how to achieve desired results when performing more complex measurements.
® PI-MAX 4 Camera System Issue 10 Safety Precautions When biased ON, intensified CCD cameras such as the PI-MAX4 can be permanently damaged if continuously exposed to light levels exceeding twice the A/D saturation level.

Internal handshakes are used to prevent: • A readout from being initiated when the timing generator is busy; •...
® PI-MAX 4 Camera System Issue 10 Micro-Channel Plate (MCP) Bracket Pulsing The primary advantage gained from incorporating gating is that it allows temporal discrimination against background light. By allowing the photocathode to “see” only during the event of interest, very high background illumination levels can be tolerated without materially degrading experiment results.
Chapter 6 LightField and Gated Operation 6.4.1 Bracket Pulsing in LIF Measurements Most experiments using laser-induced fluorescence to probe combustion flows are performed with UV probe/lasers. Atomic emission from flames also has significant UV content. If the flame is continuous, the UV background will also be continuous. Even where a flame is transient (e.g.
® PI-MAX 4 Camera System Issue 10 Also, keep in mind that MCP bracket pulsing adds 10 ns delay to the photocathode gating. Even though the bracket timing is controlled automatically by the software, in an experiment where it is necessary to delay the arrival of the laser pulse at the sample, this will mean inserting an additional delay of 10 ns (min gate delay = ~25 ns, with bracket = 35 ns) to accomplish coincidence at the camera.
Chapter 6 LightField and Gated Operation 6.4.5 Configuration MCP Bracket pulse implementation is enabled by selecting Bracket Pulsing ON from within the host software. Figure 6-2 illustrates the timing diagram for bracket pulsing. NOTE: Because Gen III Intensifiers do not respond in the UV, bracket pulsing is not available for these intensifiers.

Chapter 7 WinX and Gated Operation Figure 7-1: Timing Diagram: MCP Bracket Pulsing Photocathode Gating MCP Gating ~1 μs For emitted photoelectrons to be accelerated in the MCP, the MCP must be biased ON. In conventional intensified cameras, the MCP is biased ON continuously. In PI-MAX4, however, when bracket pulsing is ON, the MCP is biased OFF until just before the photocathode is gated ON and is biased OFF shortly after the photocathode is biased OFF.

Chapter 9: LightField and Dual Image Feature The purpose of the PI-MAX4 Dual Image Feature (DIF) is to acquire a pair of gated images in rapid succession. The time between frames can be as short as 450 ns: the second image will have some remnants from the first image due to the longer persistence of the P46 phosphor.
® PI-MAX 4 Camera System Issue 10 Frames to Save must be a multiple of two (2) and is configured on the Common Acquisitions Settings expander. See Figure 9-2. Figure 9-2: Common Acquisition Settings Expander In addition, it is recommended that the intensifier have a fast decay phosphor (P46.) Since DIF operation involves acquiring images in rapid succession, phosphor persistence can become the limiting factor in the rate of image acquisition.

Chapter 11: MCP Gating Option In MCP Gating (not to be confused with MCP bracket pulsing,) the micro-channel plate (MCP) is gated, and the photocathode gating brackets the high speed, 800 V, MCP gating pulse. This technology allows fast gating (<10 ns) of the Super Blue (SB,) slow gate intensifiers (typical gating speed ~ 200 ns) without sacrificing high QE.

Chapter 11 MCP Gating Option 11.2 Gain Variation MCP gain approximately doubles for each 50 V increase in voltage. Therefore, small ripples in the MCP voltage as a result of the gating waveform will cause gain changes that vary with time after the rising edge of the gate pulse. A gain overshoot of 20% to 30% during the first 20 ns of a gate pulse is typical, with smaller variations later in time if a wider gate pulse is used.

Chapter 12: Picosecond Gating Option The picosecond gating option for the PI-MAX4 allows optical gates down to less than 500 ps or to the lowest gate width the intensifier will support, whichever is greater. It consists of a picosecond gating board installed in the PI-MAX4 and some other modifications to support the board.
® PI-MAX 4 Camera System Issue 10 12.3 MONITOR Operation The MONITOR output at the BNC on the rear panel may be used with an oscilloscope to determine when the intensifier is being gated on. The MONITOR output is calibrated to provide a rising edge at the time the optical gate is opening (±500 ps.) The start of the MONITOR pulse coincides with the opening of the intensifier, but the width of the MONITOR pulse is unrelated to the total intensifier ON time.
Chapter 12 Picosecond Gating Option 12.5 Timing When using optical gate widths from a few nanoseconds to a fraction of a nanosecond, timing is obviously critical. The PI-MAX4 is calibrated with respect to the optical input plane (located on the front mounting plane) and the rear panel. All other propagation paths must be accounted for by the user.

® PI-MAX 4 Camera System Issue 10 14.1.2 emICCD Gain Mode In emICCD Gain mode, the PI-MAX4: EM family supports two additional modes of operation (i.e., Optimal and Manual.) Depending on the specific mode selected, the available set of mode-specific configuration parameters is automatically updated within LightField.
Chapter 14 PI-MAX4: EM Family 14.1.2.1 Optimal This is the default mode and is recommended for most applications. In Optimal mode, camera gain is set by configuring only one parameter, emICCD Gain which is located on the Common Acquisition Settings expander as part of the Intensifier configuration settings block.
® PI-MAX 4 Camera System Issue 10 • EM Gain is configured on the Analog to Digital Conversion expander. Figure 14-7 shows the EM Gain configuration parameters available for Manual Mode. Figure 14-7: Typical EM Gain Configuration Parameters: Manual Mode The desired EM Gain can be specified manually using the keyboard, or adjusted using the slider bar located just below the field.
Chapter 14 PI-MAX4: EM Family Once an EM Gain value in excess of 100 has been entered, an Experiment Warning is raised by LightField. See Figure 14-8. Figure 14-8: Typical EM Gain Configuration Display for EM Gain > 100 NOTE: When switching operation between Optimal and Manual modes, any configuration settings or adjustments made within Manual mode will be retained.
® PI-MAX 4 Camera System Issue 10 14.2 Kinetics Kinetics is a specialized imaging mode in which a small region of a CCD’s sensor area (typically referred to as a window) is exposed to incoming light while the balance of the sensor area is temporarily masked to prevent exposure.

15.1 Overexposure Protection WARNING! Image intensified cameras such as the PI-MAX4 can be destroyed if exposed to excessive light levels. Teledyne Princeton Instruments cannot take responsibility for damage due to misuse. Intensified cameras must not be continuously exposed to high-level radiation ( 10 foot candles.) When the illumination level is not quantitatively known, toggle the I.I.T.
® PI-MAX 4 Camera System Issue 10 15.2 Signal Delay For the camera to see a transient signal, it is essential that it be gated on when the signal arrives at the camera. If this requirement is not given careful consideration, it is possible to set up an experiment in which the signal will come and go before the camera is gated on.
Chapter 15 Tips and Tricks 15.2.2 Measuring Coincidence In addition to preparing a Time Budget, it is advantageous if you can directly measure the timing of the critical signals. A fast oscilloscope can be used for this purpose. Without an oscilloscope to monitor the signals, it will be difficult to determine the timing with sufficient accuracy.
® PI-MAX 4 Camera System Issue 10 15.2.3 Adjusting the Signal Delay The PI-MAX4 internal timing generator gives the user wide latitude with respect to adjusting the delay between the time the timing generator is triggered and the time the Gate On and Off edges are generated.
Chapter 15 Tips and Tricks 15.3 Lasers Pulsed lasers are used in many experiments where a gated intensified camera might be used to recover the signal. For example, in combustion measurements, a laser pulse might be applied to a flame and the resulting fluorescence studied as the signal to be analyzed.
® PI-MAX 4 Camera System Issue 10 15.3.3 Jitter Jitter, uncertainty in the timing of the laser output, is a critical laser performance parameter in gated experiments. If the jitter is significant relative to the duration of the signal pulse, the gate width will have to be wide enough to accommodate it, and the temporal discrimination against unwanted signal will be reduced.
In addition, a small offset is built in to prevent noise or pattern from going below zero. Every device has been thoroughly tested to ensure its compliance with Teledyne Princeton Instruments’ demanding specifications. 15.7 Temperature Lock...
