HAM2-ISI - Final In-CHamber Testing
Transfer functions were measured on HAM2-ISI overnight. They show good concordance with their counterpart at LLO*.
Linearity test is clean and slopes are within requirements (variation from average <1.5%).
| Slope | Offset | Average slope |
Variation from average(%) |
|
| H1 | 1.82 | -3939.89 | 1.83 | -0.37 |
| H2 | 1.81 | -1903.29 | -1.05 | |
| H3 | 1.85 | -474.80 | 1.43 | |
| V1 | 1.34 | 1291.50 | 1.34 | -0.39 |
| V2 | 1.34 | 139.11 | -0.16 | |
| V3 | 1.35 | -993.25 | 0.55 |
All other tests are satisfiying.
SEI is comfortable closing up this chamber too.
Note: One should be careful not to touch the cables that make a loop from Stage-0 to Stage-1 when closing up.
* LLO measurements were taken with PR3 on.
