Offline analysis G22-201/R89 |
|
|
Offline analysis data file G22-201/R89_0 to R89_13 (c. 6h40m data)
DSSSD#1 & 3 36.54mm -> ~ 2.3-8.6 deg
DSSSD#2 & 4 64.60mm -> ~ 4.1-10.4 deg
Beam ~1.06MeV/u 15N5+
Sort program variables https://elog.ph.ed.ac.uk/CARME/240530_180659/variables.dat
ADC data corrected for ADC offset but not gain (assume 0.7keV/LSB)
per DSSSD m_p verus m_n - attachments 1-2
For spectra below events must satisfy condition 0 < m_p < 4 *and* 0 < m_n < 4
gated w(1)=50 & w(2)=-50
20keV/channel nominal
per DSSSD p+n junction strip versus n+n Ohmic strip - attachment 3
note - x/y channel ordering to be checked
per DSSSD E_p versus E_n - attachments 4 & 6
check whether vertical structures (correct E_n but low E_p) are associated with specific strips or edge of DSSSD?
per DSSSD E_p versus E_n - attachment 5 & 7
expanded view high energy events
DSSSD #1 E_p + DSSSD#4 E_p - attachment 8
DSSSD #2 E_p + DSSSD#3 E_p - attachment 8
DSSSD #1 E_p versus DSSSD#4 E_p - attachment 9
DSSSD #2 E_p versus DSSSD#3 E_p - attachment 9
note clusters of events at asymmetric energies but only for one combination of detectors - random events?
