Belle Stack 4: 2 DSSD -z, Origami #3, #1, wedge new #2

HV = +-2.5V, Ibias=14.5uA

Position: APVs #2, 7, 11, 15 | # 17/18, 21, 25, 29

= n: 2DSSD #1/2, Origami3 #1, Origami1 #1, wedgenew #1

NO DATATAKING BECAUSE OF POWER FAILURE AT NIM CRATE (counter finster, warum?). Georg schaut sich das an, sobald in der zone access ist.

Auch AnnekathrinPC ist nicht erreichbar.

Beam shape on n side (horizontally) different than in previous runs. Number of triggers per spill is reduced to ~60k (was 200..250k before). Reason unknown.
