- no timewarps
- deadtime aida05 c. 37% and 39% due to high SC41 scaler input to MACB - issue subsequently fixed

Data analysis assumes
- all LEC ADC data channels with valid ADC offset included (507 of 512 channels)
LEC calibration ADC offset only
- no clustering
- no multiplex timestamp correction
- no p+n junction side - n+n Ohmic side correlation time gates
- FEE64 *not* DSSSD strip ordering
- hardware - slow comparator setting p+n junction FEE64s 100keV, n+n Ohmic FEE64s 150keV
- LEC energy difference +/- 168keV
- HEC energy difference +/- 1.68GeV
- valid LEC events
p+n junction side multiplicity = 1 and n+n Ohmic side multiplicity = 1
151keV < LEC energy < 1000keV
to select candidate beta events
standalone analysis of AIDA data, no downstream veto detector
- valid HEC events
p+n junction side multiplicity > 0 and n+n Ohmic side multiplicity > 0
(x,y) strips corresponding to maximum energy
p+n junction and n+n Ohmic side HEC
- HEC veto
not available - only 1x AIDA DSSSD installed
- per pixel implant-decay correlations
- end of event
difference in WR timestamp between successive ADC data items > 2500 and overall event length < 33us
per FEE64 LEC ADC data items 268ms/channel - attachments 3-5
- all
- 150keV < energy < 1500keV
- energy > 1500keV
absence of high instantaneous rates on spill cf. S181, S100, S505 etc
spill structure visible for energies > 1500keV - probably to be expected as majority of such events should be light ions
per FEE64 HEC ADC data items 268ms/channel - attachments 6-8
- all
- 100MeV < energy < 1000MeV
- energy > 1000MeV
Implant & decay event rates 262us/channel - attachment 9
LEC m_p versus m_n - attachment 10
LEC e_p versus e_n - 20keV/channel - attachment 11
HEC x strip versus y strip - attachment 12
- HEC-LEC implant decay time difference <1s

HEC x & y strip versus implant-decay time difference (4.194ms/channel) - attachment 20
HEC-LEC implant-decay time difference (8.389ms/channel) for candidate 82Nb events - attachment 21
- blue - forward
- cyan - backward
Note
- no FRS PID
- no HEC dE
- no HEC veto
- no HEC energy gates - assume all events within x-y window *stop* in AIDA DSSSD - 82Nb events known to overlap in x-y with (longer-lived, more numerous) 83Nb events
- no front-back time difference
- no clustering
- *all* LEC channels with valid ADC offsets (507 of 512) included *except* 2x strips 130 & 136
HEC-LEC implant-decay time difference (8.389ms/channel) for candidate 82Nb events - attachment 22
Weighted least squares fit channels 1-12 half life 55(9)ms cf. NNDC 50.0(3)ms. |
