QA BEAMCHECKER™ PLUS 71
CONSTANCY
Constancy of measured energy, calculated from the center
ionization chamber compared to baseline center ionization
chamber value
TEMPERATURE
Internal temperature when measurement was taken, in °C
PRESSURE
Pressure when measurement was taken, in mmHg
ENERGYLEVEL
A unique identifier for the energy as determined by several
ionization chambers and a proprietary algorithm. This is then
compared to the set of ENERGYLEVEL values from baselines
above
LEFT_OUTPUT
Left channel output (temperature/pressure corrected)
LEFT_OUTPUT_%DELTA
Left channel output difference from baseline
CENTER_OUTPUT
Center channel output (temperature/pressure corrected)
CENTER_OUTPUT_%DELTA
Center channel output percentage difference from baseline
RIGHT_OUTPUT
Right channel output (temperature/pressure corrected)
RIGHT_OUTPUT_%DELTA
Right channel output percentage difference from baseline
TOP_OUTPUT
Top channel output (temperature/pressure corrected)
TOP_OUTPUT_%DELTA
Top channel output percentage difference from baseline
BOTTOM_OUTPUT
Bottom channel output (temperature/pressure corrected)
BOTTOM_OUTPUT_%DELTA
Bottom channel output percentage difference from baseline
CENTER_RAW
Data collected from the center ionization chamber during
measurement
LTP_RTE_RAW
Data collected from the left (photon side) or right (electron side)
ionization chamber during measurement
TOP_RAW
Data collected from the top ionization chamber during
measurement
RTP_LTE_RAW
Data collected from the right (photon side) or left (electron side)
ionization chamber during measurement
BOTTOM_RAW
Data collected from the bottom ionization chamber during
measurement
ONE_MM_ALUM_RAW
Data collected from energy channel 1 during measurement,
primarily used for electrons
SIX_MM_ALUM_RAW
Data collected from energy channel 2 during measurement,
primarily used for electrons
SIX_MM_LEAD_RAW
Data collected from energy channel 3 during measurement,
primarily used for photons
NUM_SAMPLES
Number of samples collected by the analog-to-digital converter
during the measurement
COMMENT
Measurement comment entered using the Data View interface
