4 System Manual Issue 4
The following items are standard with all PI-MAX4 systems:
•Camera
The PI-MAX4 camera houses the CCD and intensifier and it supplies all of the high
voltages needed to operate the intensifier (refer to Chapter 3, System Setup, for
more information.)
Cooling within the camera is performed by a cooling fan and a multi-stage Peltier
cooler that is thermally coupled to the CCD (liquid coolant circulation can also be
used for the PI-MAX4 camera.) Photocathode cooling to reduce equivalent
background illumination (EBI) can be achieved via a chilled dry nitrogen source.
C-, F-, and Spectroscopy-mount adapters are supplied (one of which is
factory-installed.)
The camera can be operated in one of the following two modes:
— Safe Mode
In Safe mode, the photocathode is gated off.
— Gate Mode.
In Gate mode, the photocathode is biased on only during the time each gate
pulse is applied.
The PI-MAX4 contains the analog and digital electronics, scan control and
exposure timing hardware, and controller I/O connectors. Readout modes supported
include full resolution, simultaneous multiple sub-images, and non-uniform
binning. Single or multiple software-defined regions of interest can also be tested
without having to digitize all the pixels of the array. Flexible exposure, set through
software, is also fully supported.
The PI-MAX4 contains two High Speed analog-to-digital converters. The effective
digitization rate is software-selectable. After the data is converted, it is transferred
directly from the camera to the host computer memory via the high speed interface
cable.
