Vertical cosmic rays of EPD with SS14081516 and SS17181920 configurations

Updated on Mon, 2017-09-25 10:40. Originally created by tchuang on 2017-09-25 00:54. Under:

 SS14081516 configuration:

This is the fourth set of cosmic tests done.
 
SS14 = FEE01  (Note that the hand-written label on the card says "7", but that is irrelevant here
SS08 = FEE02
SS15 = FEE03
SS16 = FEE04
 
>->->->->->->->  This set is the first to use this new FEE mapping.  See page 111 in log book.

Notes:
 
1] In order to look at tile #1, we have to re-cable (since we have only 60 ADC channels
but 64 odd-numbered tiles).
FEE01TT01 ---> ADC in slot 5 channel 2   (where FEE01TT31 normally goes)
FEE02TT01 ---> ADC in slot 9 channel 5   (where FEE02TT31 normally goes)
FEE03TT01 ---> ADC in slot 15 channel 8  (where FEE03TT31 normally goes)
FEE04TT01 ---> ADC in slot 22 channel 11 (where FEE04TT31 normally goes)
 
Note that, unlike previous cosmic set-ups, "tile 1 goes where tile 31 normally goes"

SS17181920 configuration:

This is the fifth set of cosmic tests done.
 
SS17 = FEE01  (Note that the hand-written label on the card says "7", but that is irrelevant here
SS08 = FEE02
SS19 = FEE03
SS20 = FEE04

2] Te-Chuan has been seeing essentially zero vertical cosmics for TT30,31.
This could be an index problem in his code (i.e. bug), but in principle
it could be caused by us not putting the trigger detectors all the way
under the largest tiles. (They are at the edge of the shelf, so we might
be "shy" to put the trigger detectors there.)  For odd_Configuration2,
