- BaseLineLength (long) The current size of the baseline data buffer.
- BaselineThreshold (double) Baseline filter threshold, in eV.
- Buffer (long, 2048 * 4096 (1D), mapping mode feature) Filled with the
MCA spectra for each
channel and each pixel. No header information is included.
- BufferLength (long, mapping mode feature) No. of valid long-words in buffer.
BufferLength is set to 0 by the command StartMapping.
- CalibrationEnergy (double) in eV
- CurrentPixel (long, mapping mode feature) The number of the current pixel,
less than NumMapPixels.
- DecayTime (double) The decay time for RC amplifiers, in musec, ignored for
RESET type amps.
- DetectorPolarity (double) the input signal polarity, '1' for positive, '0' negative.
- FlagThreadBusy (long, mapping mode feature) The flag is 1 as long
as the thread is busy.
- GapTime (double) The gap time for the energy filter, in musec, read-only, this
value can be set via MinimumGapTime.
- GateIgnore (double) Determines whether acquisition continues or halts
during pixel advance while GATE is asserted.
- GateMaster (double) Sets the current module as a GATE master module, 1.0.
- ICR (double, read-only) Input count rate, in counts per second
- InputLogicPolarity (double) Sets the polarity of the logic signal connected
to the front panel, non-inverted 0, inverted 1.
- LiveTime (double, read-only) The calculated energy filter live time, in s.
- MappingData (long, 2048x4096 (2D), mapping mode feature) Filled with the
MCA spectra for each
channel and each pixel. Each line in the image represent one spectrum. The number of lines corresponds to the number of triggers took in mapping mode. No header information is included.
- MappingMode (double) 0.0 standard MCA, 1.0 full spectrum mapping,
2.0 multiple SCA mapping.
- MappingModeChannel (long, mapping mode feature) the channel selected for mapping mode.
- Maxwidth (double) Minimum peak width for pile-up inspection, in muse
- McaBinWidth (double) The width of an individual bin, in eV.
- McaLength (long) The current size of the MCA data buffer.
- MinimumGapTime (double) The minimum gap time for the energy/slow filter in musec.
- NumberMcaChannels (long) The number of bins in the MCA spectrum.
- NumChan (short) 1 because there is one channel per server.
- NumMapPixels (long, mapping mode feature) The total number of pixels per run.
- NumMapPixelsPerBuffer (long, mapping mode feature) The number of pixels per buffer.
There are 2 buffers, a and b. Each has the size of 1048576 16-bit words.
The structure of each buffer is: buffer-header (256 words),
pixel header (256 words), pixel data ( 4 x NumberMcaChannels words),
pixel header( 256 words), pixel data ( 4 x NumberMcaChannels words).
If the MCAs have 8192 channels, 31 pixels can be stored in a buffer.
- NumMod (ushort, read-only) The number of DXP-XMAP modules
- OCR (double, read-only) Output count rate, in counts per second
- PeakingTime (double) Peaking time of the energy filter, in musec.
Longer peaking times produce better resolution at the cost of deadtime.
HPGe have peaking times between 16 and 32 microseconds. Silicon drift
detectors use 10 microseconds or less.
- PixelAdvanceMode (double, mapping mode feature) Advance pixel by gate: 1,
by SYNC signal: 2.
- PreampGain (double) Preamplifier gain, in mV/keV
- PreampType (double) 0 RESET, 1 RC
- PresetType (short) 0 - no preset, 1 - fixed realtime, 2 - fixed livetime,
3 - fixed events, 4 - fixed triggers
- PresetValue (double) Number of counts or seconds depending on PreseType.
- RealTime (double, read-only) in s.
- ResetDelay (double) The amount of time that the processor waits after the
detector is reset before it processes the input signal, in musec. ignore,
if the preamp type is not RESET.
- Spectrum (long, 16385, read-only) Data spectrum.
- TriggerLiveTime (double, read-only) in s.
- TriggerGapTime (double) the gap time of the trigger filter, in musec.
- TriggerPeakingTime (double) The peaking time of the trigger filter, in musec.
- TriggerThreshold (double) Trigger filter threshold, in eV.
