ITEMS FOR DISCUSSION:

  • NPS ELECTRONICS TESTS (Alexandre)

Got the FADC trigger board this week. Have one FADC and VXS crate in test lab. Can start setting up. Need to follow up with Alexander Somov for borrowing a CTP.


Quick look at effect of 4 ns jitter and 250 MHz on pulse shape. I took the PbF2 reference shape and summed over 4 ns, shifting by 1 ns, 2ns,3 ns and 4ns the start of the integral. It does not fluctuate as bad as I thought so trigger should work. To be tested with real hardware. [resumming of 1 GHz to 250 MHz]

downsampling

Carlos is looking at elastic data to determine effect of lower sampling rate on energy resolution and timing, will show results maybe at next meeting.
