HWSX

Today we started off by making sure that the green beam is aligned to the irises. We quickly found that the outgoing path of the sled beam and the green beam didn't quite overlap. We adjusted HWSX BS and HWSX SOURCE M2 optics to realign sled beam to the irises. After we ensure that the sled and green overlap we centered the HWS beam onto the HWS camera and adjusted the pick off BS to align the green to the BASLER camera (Richard insisted it's not a GigE so I'm going to stop calling it that). We also mount the camera to the height-adjustable mount. We also put the IR bandpass filter onto the camera and verified that the camera can actually see the 790nm sled by putting it right in front of the sled launcher. Right now we can't see the sled on the BASLER camera and we couldn't change the exposure rate (as of now anyway). We need something more sensitive (a flipper mirror alone wouldn't work either since the camera wasn't able to see any light coming off the final mirror before the HWS camera). 

HWSY

We wanted to see some HWSY data so we went in to make sure that Y sled was not clipped or whatsoever. The beam looked as bad as usual. We made some minor tweak to the green beam and the sled so that their path overlap. We also identified the top beam to be a beam reflected off the compensation plate (to figure this out we yawed the CP then put it back in place). Since we have only one spare sled left, we decided not to replace it until after the vent work.

HWS Code

Starting from 22:00:21 UTC today (April 18) the code is writing data from HWSY camera. Will revert this configuration as soon as I get some power up/down time.
