(Corey, Jax, Keita)

Continue with getting a GREEN beam onto the TMS table.  We had to make more position changes for the GREEN Top Periscope Mirrors (this required using longer screws for the top dog clamps [see photo]).  Then most of the time was spent pointing the beam onto TMS.  Once on the TMS, the beam was then pointed onto the QPDs first with a TMS Periscope mirror, but most of it was via ISCTEY mirrors by Jax.  We went through several iterations of tweaking to stay centered on the mirrors and to also have a beam nice & centered on the ISCTEY periscope mirrors (this involved some nap time in the chamber while Jax did all the work outside [see photo]).

Through this alignment work, we could see the retro-reflected beam off the ETM on the TMS Telescope Mirrors.  On the Secondary mirror the spot looks to be low and little off in yaw.  To fix the pitch, we will need to pitch the TMS "back" via the slider weights under the table.

Additionally, during this alignment work, the QPD servo was engaged & is operational!
