Fig 1: 2D hit pattern of each AIDA DSSD for MBS run 24 (40Ar primary beam, centred)

Low statistics in DSSD2 partly due to low energy deposition

Fig 2: Position according to TPC42 (ca. 2 metres before AIDA)

Fig 3: 2D hit pattern of DSSD 1 for MBS run 37 (34Si fragments, no PID gate)

-
Bottom part of AIDA noticably cut off - rotation in DSSD also noticed (not an issue)

Snout was investigated and platform was discovered to not be fully level by Bogdan using a laser level - he has adjusted it so that the AIDA snout is now level to within 1 mm.
(The beam right side was previous 4-6mm below the beam left side)

Y cut in fragment run is currently of unknown origin. Optics are being investigated

Fig 4: Hit pattern of 40Ar with strip offsets fixed (no missing strips)

Fig 5: Energy loss in DSSD1 of 40Ar primary beam

Fig 6: TPC 41, TPC 42, AIDA X comparison

Fig 7: " Y comparison

Fig 8-11: As above for 34Si run

Y cut unknown still.
