ACD Rate Tests
Shift log activities: Swing
Jan/03/2006
See Run
database for run ranges 135005171-135005182 for run config/data
details. The ACD tile number vs tile name map can be checked from the GEM
ICD appendix.
First ACD rate test with ACD integrated on full LAT. Only ACD ROI triggers enabled. Nominal threshold is ~0.2 MIPs. The scale is reserved so that -2 means a higher threshold than nominal.
| Run | Thresholds | Free Boards | Results/Comments |
| 135005171 | Nominal | All | Input ~2.3KHz. ~90% deadtime from LATTE. Log ~230Hz. |
| 135005175 | Nominal | 2 (2LA) | Only enabled tile num=0xc (022). Rate = 35 Hz. |
| 135005176 | Nominal | 4 (2RA) | Only enabled tile num=7 (012). Rate = 35 Hz. |
| 135005177 | Nominal | 8 (4LA) | Only enabled tile num=0x54 (403). Rate = 35 Hz. |
| 135005178 | Nominal | 5 (2RB) | All channels on free board. Input ~ 400 Hz, deadtime ~40%. |
| 135005179 | Nominal | 11 (4RB) | All channels on free board. Input ~380 Hz, deadtime ~38%. |
| 135005180 | Nominal | 4 (2RA), 5 (2RB) | All channels on free boards. Input ~530Hz, deadtime ~50%. |
| 135005172 | -2 | All | ~85% deadtime |
| 135005173 | -4 | All | ~82% deadtime |
| 135005174 | -6 | All | ~80% deadtime |
| 135005181 | -8 | All | ~77% deadtime |
| 135005182 | -10 | All | ~74% deadtime (input rate ~1Khz) |
