Standard Imaging QA BEAMCHECKER PLUS - Physics Mode

QA BEAMCHECKER™ PLUS 72
14.5 Physics Mode
The exported file for the Physics mode is broken into 3 sections: Rate Data, Charge Data, and
Mode Specific. The rate and charge sections are the same for all three room types, however,
the information exported for Section 3 varies by mode as described below.
