Run 374 - good beam conditions |
|
|
The 18O was very stable between 0h and 2h around I ~ 4.5 ľA.
CAVIAR ~ 161k; CATS1 ~ 88kcps; CATS2~ 111kcps ; CHIO ~ 106kcps; PLASTIC ~ 105 kcps.
The dead time is between 4 and 7%.
It was slowly decreasing to 3.7ľA at 2h45.
Between 2h48 and 3h we see strong fluctuations of the primary beam current I down to 3.7ľA and to 0.5ľA.
We call the PCP machine, they tell us that they manage to recover the beam, and that there are strong instabilities at the source.
At 3h15 the beam is stable again, around 4.2ľA.
