This afternoon I went into HAM1 chamber and installed PM1 which is a Tip Tilt suspension (ICS link - D1001396-07, previously ZM1 in HAM5). PM1 is currently sitting at the edge of the table (as shown in the picture here) and will be later moved to its final position sometime this week. The suspension was clamped down with four dog clamps. The other information related to PM1 is listed below,
- The BOSEMs have the following serial number - D060106-C s/n 583, s/n 562, s/n 263, s/n 201
- The quadrupus cable for the BOSEMs have the following S/N - D1000234 - S1000695 (length 55in).
I have applied the following offsets and gains in the OSEM input filter of PM1 and accepted it in the SDF, see here.
| OLC | OFFSET | GAIN |
| 26440 | - 13220 | 1.13 |
| 28894 | - 14447 | 1.04 |
| 24529 | - 12264.5 | 1.22 |
| 29276 | - 14638 | 1.02 |
I switched on the coil drivers (Rack C4 in the CER, page 14) and satellite amp (floor SUS R1, page 13), as per the systems wiring diagram for HAM1 - D0902810.
I am currently testing the electronics chain and will post the results (osem spectra and transfer function measurements) asap.
Late entry:- Yesterday, we moved SUS PM1 to its desired location in HAM1 chamber. Later we were able to fine tune the position mechanically (including the pitch and yaw of the mirror) with the IR laser beam. The pictures are attached below.
This morning I found that the Voltmon for PM1 was not working, Daniel fixed it by switching on the filter modules associated with it. Earlier, I crosschecked the wiring and chassis in the CER to confirm they are correctly attached and switched on.
