RIKEN data e.g. https://elog.ph.ed.ac.uk/AIDA/583 - more low energy HEC events? Attachment 17 - per DSSSD HEC p strip versus n strip - no conditions - z_hec=1 (DSSSD#1) and z_hec=3 (DSSSD#2) - z_hec=1 => implant stops in DSSSD#1 - z_hec=3 => implant hits DSSSD#1 and DSSSD#2 but does not necessarily stop in DSSSD#2 Attachment 18 - per DSSSD HEC E_p versus E_n - x and y axes 20MeV/channel Attachment 19 - DSSSD#1 HEC E_p versus DSSSD#2 E_p - x and y axes 20MeV/channel Attachment 20 - DSSSD#1 LEC E_p versus DSSSD#2 E_p - x and y axes 20keV/channel - y=0 12816818 - x=0 7374435 - x>0 and y>0 2295693 Attachment 21 - per DSSSD per pixel time difference between successive HEC events (4.096us/channel) - minimum time difference c. 36us which make sense - c. readout time of ASIC with all 16 channels active - origin of 9 channel period spectrum structure? Attachments 22-23 - per DSSSD per pixel time difference between HEC and LEC events (4.096us/channel) Attachments 24 - per DSSSD per pixel time difference between HEC and LEC events (1s/channel) - for ions stopped in DSSSD#1 or DSSSD'2 - no PID selection - minimum time difference c. 88us - effect of high on spill deadtime apparent per S100 analysis Attachment 25 - per DSSSD per pixel time difference between HEC and LEC events (1s/channel) versus - HEC energy - LEC energy - p and n strip Attachment 26 - per DSSSD implant and decay event p strip - n strip time difference (2us/channel) - wider distribution for implant events expected due to number of ASIC active channels in implant events - most decay events +/-2us - lower ASIC occupancy for decay events so most events will be from same (or adjacent) clock cycle Attachment 27 - per DSSSD decay event p strip - n strip time difference (2us/channel) versus decay (E_p - E_n) (20keV channel) Encoding: HTML ELCode plain Suppress Email notification
