New page

I did some TDC ring tests on Detector 4 by adding a 50 Ohm pass through terminator on the base of the top detector and another pass through terminator at the exit of the patch pannel

I needed recommission the DAQ TDC logic which seems to have become unplugged.

I added connectors so TDC1190[6] would have two hits separated by 400 ns

Run 4518
