This test was done by reducing the discriminator thresholds on the BB to get high rates. T1 ~ 47Khz ; T2 ~ 2.6Khz ; T6 ~ 190Khz
Unbuffered Mode: -------------------------------------------------------- Run # | Input rate(KHz) | L1A rate(KHz) | DT(%) from datamon | -------------------------------------------------------- 1046 0.6 0.55 4 (8%) 1045 1.2 1.0 10 (17%) 1044 1.8 1.4 13 (23%) 1043 2.5 1.8 18 (28%) --------------------------------------------------------Buffered Mode: ----------------------------------------------------------- Run # | Input rate(KHz) | L1A rate(KHz) | DT(%) from datamon | ----------------------------------------------------------- 1047 0.6 0.6 0 1048 1.2 1.2 0 1049 1.8 1.75 0 effectively ~3% 1042 2.5 2.2 0 " ~4% 1050 3.0 2.8 0 " ~8% 1051 6.0 4.0 8 " ~33% --------------------------------------------------------
The DT in brackets is what we expect roughly from the L1A rate and input rate. but due to correlations in the triggers the datamon was showing less that what we expect(?)
I guess this study really have to be done with beam to get better idea. In any case in buffered mode we can at least take 3 KHz, I think.
