Calibration runs for kinemtics #28
16:00 2489 10 cm Al dummy target with raster ON, I = 30 micro Amperes.
2490 10 cm Al dummy target with raster OFF, I = 5 micro Amperes.
2491 4 cm Al dummy target with raster OFF, I = 5 micro Amperes.
2492 12C target raster OFF, I = 50 micro Amperes.
17:05 We asked for acces in order to change HRSH angle above 82 deg.
and we started the momentum change. The new kinematics is #29:
theta_HRSH = 89.95 deg (requested angle)
p_0_HRSH = 1171 MeV/c. (requested value)
18:00 End of access.
18:15 Beam back
18:17 Harp scans + CODA run with new PS:
with raster OFF: gain 8 on both scanners I = 5.15 micro Amperes.
scan_556.dat and scan_557.dat + run number 2493.
with raster ON: gains 64 (#5) and 32 (#6), I = 5.3 micro Amperes.
scan_558.dat and scan_559.dat + run number 2494.
Calibration runs kinematics number 29:
18:35 2495 12C target with raster OFF, I = 50 micro Amperes.
2496 4 cm Al dummy target raster OFF, I = 5 micro Amperes.
2497 10 cm Al dummy target raster OFF, I = 5 micro Amperes.
2498 10 cm Al dummy target raster ON, I = 30 micro Amperes.
