| YR00DA1ZB is the channel for PMT rate. |
Fri May 31 21:53:20 2024, CB EM, JM,EM AB, Overnight beam tests 17x
|
22:53
Run 15 started
Beam tests. We increased the storage time to 2min and switched to bunched beam so that we can see the beam lifetime over the cycle. |

Wed Jan 31 09:49:38 2024, JM, TD, Optimising - Wednesday 31 25x
|
Removed ground from DSSD #1 to the chamber and set MACBs so that timestamp is from the NIM WR emulator not the VME VETAR2.
Root MACB mode 0x3 -> 0xd - all other MACB modes 0x3 ( unchanged ).
No timestamps observed from the emulator. Re-set to take timestamps from the VETAR" unit -> all timestamps observed. |

Tue May 13 15:07:42 2025, JM, Online monitoring code
|
CARME_Sort histogramming has been updated to aid our understanding online.
> XY plots have been updated to reflect the true position of the beam relative to each detector. Online we will be able to layout in a grid
to reflect looking downstream in YR09 (see attachment 1) |
