- Fabrication
- A new puck manipulator made out of Teflon and 24 inches long was designed and drawing submitted to the shop for fabrication. This manipulator will be used to insert pucks into the spherical electrode while still mounted to the gun vacuum chamber during S&A and laser retro-reflection checks in the LERF Lab 3A clean room.
- File:JL0163328, PUCK MANIPULATOR END ADAPTER TEFLON 24 in long.pdf
- S&A checks of the R30-3 gun in LERF Lab 3A clean room took place on Tuesday March 26 2024. See details [[1]]
- The R30-3 gun vacuum chamber was mounted by Neil Wilson and Bern Johnson on a sturdy 80/20 frame table with optical breadboard top.
- S&A surveyed the gun chamber to find the chamber z axis.
- Then S&A established a laser launch coincidental with the gun chamber z-axis
- As preliminary testing, we inserted a mirror puck. The retro-reflection indicates the plane of the mirror puck is ~ 0.8 degree w.r.t. the chamber axis.
- We will do more retro-reflection testing with a molybdenum puck and GaAs wafer once the Teflon puck manipulator arrives from the shop.
