Chapter 7: Operation
This chapter provides general operation factors that apply to Gate Mode operation of
the PI-MAX3 system. The following factors play a part before, during, and after the
exposure and readout of the CCD array:
• Dark Charge;
• Clean Cycles,
• Continuous Cleans;
• Exposure Modes;
• Readout;
• Digitization;
• Software binning;
• Background Subtraction.
Factors specific to an intensifier mode and pulser are discussed in the appropriate
chapter.
7.1 Data Acquisition Sequence
When data are acquired, the CCD array is exposed to an incoming signal which
integrates on the array. At the end of the exposure which may include multiple gates
the charge from the array pixels must be read out, digitized, and transferred to the host
computer before the image from the array appears on the computer screen. This is
illustrated in
Figure 7-1 .
