ITMY HWS alignment work

Elli, Nutsinee

Today we moved theITMY HWS periscope to fix the return beam clipping issue (it was clipped at the lens between the two periscope mirros). I lost the green beam during the alignment (ITMY misaligned) so I left it there for now. The return beam seems to be clipping at the edge of the first iris (the green came right through the center though). *Should* be a quick fix next time (don't I always hope that?).
