Subject: Epoxy glue on PMC mirror and PZT 

 

The glue is dry and the back PMC mirror is steady. we are ordering the o-ring for clamping flat mirrors on the pmc. See more pictures here.

Assembly work

  • We checked with the epoxy left in the mixing cup. It was hardened nicely.
  • When I bent it, it was britten. So I think the position should be fixed nicely because the epoxy is rather hard, not gummy
  • The PMC parts  (body, mirror clamps, screws) were cleaned with soap water and isopropanal. 
  • However, the O-rings planned to put between the window clamp and the mirrors are too small. Antonito is ordering a bigger one.
  •  

To do next:

  • If the oring- size match with the window, we can proceed. If not we will use Kapton tape like Zach did with his PMC see ATF:1543
  • Test the PMC range, The max-min for PZT range should cover ~ 4 GHz so it can follow the short cavity (FSR = 4 GHz). We had some problems locking PMC and the ref cav last time because PMC could not span the short cavity's FSR.
  • If possible, check the Finesse.
