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.
Section 1 - Rate Data (Same for All Modes)
Data collected from the top ionization chamber during measurement
Data collected from the left ionization chamber during measurement
Data collected from the center ionization chamber during measurement
Data collected from the right ionization chamber during measurement
Data collected from the bottom ionization chamber during measurement
Section 2 - Charge Data (Same for All Modes)
Data collected from the top ionization chamber during measurement
Data collected from the left ionization chamber during measurement
Data collected from the center ionization chamber during measurement
Data collected from the right ionization chamber during measurement
Data collected from the bottom ionization chamber during measurement
Section 3 - Mode Specific (Static 5 Channel)
Flatness of baseline energy, calculated from the ionization chamber
readings
Transverse symmetry of baseline energy, calculated from the ionization
chamber readings
Axial symmetry of baseline energy, calculated from the ionization chamber
readings
Internal temperature when measurement was taken, in °C
Pressure when measurement was taken, in mmHg
Internal battery voltage at time of reception of 'Stop Measurement'
command, in Volts DC
Date and time when measurement was taken, in the format mmddyyyy,
hhmmss
The elapsed time of measurement
