TJ, Camilla WP# 12121. 

Current CO2Y laser: 20510-20816D which was re-gassed in 2016 and installed in October 2022 65264.

To prepare for the CO2Y laser swap next week:

•  TJ and I moved the spare CO2 laser that just got re-gassed (S/N 20706/alt link) out to the LVEA.
• Turned on the FLIR camera and checked beam position with no mask, central and annular masks. 
• Checked the beam centering on irises (used PWM for iris before power control) and used new Thorlabs VCR6S detector cards which were great!
  • The beam was to the upper left on first and second iris (didn't move irises). 
  • The beam was centered on the last two irises. 
• We didn't scribe the current CO2 position at it was already pushed up against multiple beam dumps to record it's position. 
• All water tubes were correctly labeled photo of laser pipe order, the RF driver to laser cables were labeled on both sides as they connect to the laser, see photo for how to plug into RF driver.
