CRS Build Continues on (June 9th 2026)
We've been continuing the CRS build in the H2-PSL and prepping everything to eventually be moved chamber side. 

Yesterday we cleaned the half-wave plates which were delivered late and the last part of the HoQIs needed. We are planning to dust them off with an ion gun and install them in the rest of the HoQIs today.

Finished constructing the rest of the HoQIs minus the half-wave plates and the two HoQIs with broken PD connectors.

01-SN008 and 02-SN008 were internally aligned with the following fringe viability:
01-SN008: Sin-81.5%, Cos-78.8%, MCos-81.9%
02-SN008: Sin-84.4%, Cos-82.6%, MCos-78.5%

Created/built a simulink model for the CRS. on HAM3 and got the channel names all worked out. With the library part /isi/common/models/crs_block.mdl and the proc /isi/h1/common/h1crsproc.mdl
