We transitioned the EY VEA to laser hazard and then turned on and unshuttered the EY Pcal laser (previously turned off before the Thanksgiving break). Next we checked the positioning of the two beams on the receiver module relay mirrors. The outer beam mirror required more adjustment than the inner beam mirror. The positioning was adjusted to center the Pcal beams and both beams were aligned to the center of the integrating sphere aperture. After this procedure, we shuttered the laser, turned it off, and transitioned the EY VEA back to laser safe. This work was done in preparation for the EY vent to take place in January.
