EM Test Status
Subsystem
Test Description
Req’d for
Data Taking
Status
TKR
TOT Enabled Tests – Errors vs threshold and vs TACK delay
No
Done by J. Cohen-Tanugi during swing shift.
TKR
Bad Channel List and Data Mask
Yes
Johan is generating this; configuration files will
be controlled in new I&T directory structure
TKR
TACK delay optimization per layer – charge injection
occupancy vs TACK delay and vs threshold
No
Done for (12,12) on all layers, 50 events per
point. Need to do for (0,24) and (24,0).
TKR
Efficiency vs TACK delay and vs threshold – 5-layer cosmic
ray trigger
No
Need to run 100, 1000 events, layer by layer.
Limit range of TACK; step every 5 units.
TKR
Error vs threshold test – 6-layer trigger w/ TOT enabled
No
Need significantly higher statistics
CAL
Trigger with zero-suppression turned off
Yes
Charge injection works but cosmics fails; error
may be introduced in data transfer from VME
crate to PC; will install direct ethernet cable to
avoid SLAC LAN – problem solved!
CAL
ci_singlex16 test with different HE gain settings: gain =
0,8,9,10,11,12,13,14,15. (while LE gain should be always
nominal = 5)
No
Test executed by L. Wai during day shift
CAL
CAL Comprehensive Test Set
Yes
Tests being executed by L. Wai; configuration
files will be controlled in new I&T directory
structure
CAL
5-hr Cosmic Data Set
Yes
Data sets will be collected by L. Wai and J.
Panetta
I&T
Global TACK delay optimization for external scintillator
trigger- # hits vs delay
No
Script is being prepared and tested by J. CohenTanugi
