Entry number 346228
keyword=F1 TDC mapping
There are two F1s installed. The E counters are connected to the TDC in
slot 15, and the dE counters in slot 17. The channel numbers on F1s are
non-conventional. The top right connector is channels 0,2,4,...30, the
top left connector is channels 1,3,5,...,31, the bottom right connector
is 32, 34, ..., 62, and the bottom left is 33, 35, ..., 63. I have
heard, but don't know for sure, the the Hall A analylzer class for the
F1s renumbers these channels as 0-15, 16-31, 32-47, 48-63. Given this,
the following is the map:
