We've constructed a beta trigger with the signals from the p-side of the three DSSDs (OR of all fast discriminator channels of each FEE). det1 -> NNAIDA#6 -> MACB#10.2 det1 -> NNAIDA#10 -> MACB#3.4 det2 -> NNAIDA#2 -> MACB#10.3 det2 -> NNAIDA#14 -> MACB#3.2 det3 -> NNAIDA#1 -> MACB#10.4 det3 -> NNAIDA#13 -> MACB#3.3 beta-trigger is OR of all above MACB trigger outputs. Diagram for logic circuit is in paper logbook. Bellow are some oscilloscope sceenshots. Some things to note about the MACB trigger outputs: - all show multiple outputs for each pulser input. Some channels seem to have higher level for such 'multiplicity'. - the width of the outputs varies for different channels (from ~40 ns to ~300 ns) - the delay between the pulser signal and the output from the MACB is quite large, and also different for each MACB (measured from ~800 ns up to 2 usec). Scope screenshots: - light blue is the trigger output from Pulser - dark blue is output from trigger channel of MACB MACB#10.2: tek00001.tif MACB#3.4: tek00002.tif MACB#10.3: tek00005.tif MACB#3.2: tek00007.tif MACB#10.4: tek000011.tif MACB#3.3: tek000018.tif Encoding: HTML ELCode plain Suppress Email notification
