Analysis of May2017/R1_0 to May2017/ R1_79 |
|
|
See https://elog.ph.ed.ac.uk/AIDA/555
Date files May2017/R1_0 to May2017/R_79 are an extended (c. 3.8 day) background run with
BNC PB-4 Pulser OFF and and a relatively high slow comparator threshold 0x64 to reduce
data volume.
Attachment 1 - DSSSD#1-6 m_p versus m_n
Attachment 2 - DSSSD#1-6 x versus y hit patterns
Attachment 3 - DSSSD#1-6 E_p versus E_n (dispersion ~20-23keV/channel)
Attachment 4 - DSSSD#1-6 E_p versus E_n (with tags)
Attachment 5 - 2D contour levels & colours for all 2D spectra above
Attachment 6 - MIDASsort subroutine
Attachment 7 - MIDASsort namelist I/O variables
Attachments 8-10 - ADC offset calculation logs etc
Attachment 11 - spectrum titles
MIDASsort calculates channel and ADC data as follows
ch = channel + ( module - 1 ) * 64 + ( range * 2048 )
adc_data = INT( RSHIFT( ABS( adc_data - 32768 ), 3 ) - offset(ch) + 0.5 )
where
channel = FEE channel # (0-63)
module = FEE module # (1-24)
range = LEC or HEC (LEC = 0, HEC = 1)
ADC offsets were calculated using the pulser walkthrough data of files May2017/R4
and command
cd ~/td/calibration
offsets /homes/npg/Spectra/R4 100 1400 15 10
where the peakfind peak search parameters are limits 100-1400 channels, fwhm=15 channels and acceptance=10%
Probably ~10% of ADC offsets need manual checking/adjustment
The 2D spectra (attachments 1-4) were produced for events with
multiplicities 0 < m_p < 8 *and* 0 < m_n < 8
all x-y combinations incremented
no clustering, gain matching or software thresholds
All DSSSDs show Uranium 4n+2 decay sequence background spectra from the intrinsic activity of the DSSSDs
and airborne decay products (e.g. 222Rn). Not clear why statistics are higher for DSSSD#1 cf. DSSSD#2-6.
One possibility is the activity of the aluminized Mylar window just upstream of DSSSD#1? Surrounding air
and Al snout would presumably affect DSSSD#1 and #6 about the same. |
