Start at 2019-06-28 18:34:22.873862
target 700mb
Brho0=0.90 Tm
DC pressure 6 mbar
IC pressure 120 mbar
CATS2 inserted
AGATA position +51-25 mm
TRIGGER :
- CMG
- M2
- VAMOS%1000
- CATS%1000
all X on MUVI disabled from trigger
all threshold of MUVI1 at 1 MeV to avoid as much as possible noise
beam back. Q pole issues still |
Beam is back, again, at 1.53, weird behavior of CATS |
|
After beam is back we found 350Hz on vamos focal plane, with 20kHz current. After Brho scanning we found a Brho distribution going from 1Tm to 0.4Tm. Observation of gamma rays indicates no accumulation of radioactivity in the chamber with respect to previous runs. We conclude that we may have ice layers up to 500um in the target but very in-homogeneous since we also observe 1Tm Brho. To verify maybe increase target pressure to modify the structure of the ice. CATS is tripping continuously. No VACUUM changes observed. |
