During testing, we saw that actuator V4 of HPI BS was not able to deliver full power. We didn't try to fix the problem (risk of disturbing alignment). The HEPI at the beam splitter is now controlled in position at 100mHz. We will come back to the problematic actuator later.
Some correction gains were applied to the HEPI actuators to compensate for differences in the actuator drives. The correction gains are:
DOF | Act Gain |
H1 | 1.016 |
H2 | 1.064 |
H3 | 0.957 |
H4 | 0.970 |
V1 | 0.888 |
V2 | 0.932 |
V3 | 0.978 |
V4 | 1.284 |
The offsets used on the IPSs are:
DOF | Offsets |
X | -128873 |
Y | -381126 |
RZ | -79880 |
HP | 19919 |
Z | 536676 |
