Subject: 1.45" refcav mount 

I'm working on the new mount for 1.45" refcav. I 'll discuss the design with Eric G and some mech engineers (Mike Smith, Ken Mailand) later.

cav_mount_assembly2.PDF

Here is the assembly of the mount, with only one cavity shown.

copper thermal shield around the cavity is 1.75" OD, 1.686" ID, wll thickness = 0.064", 3" long. (I'll order the tube from McMaster-Carr.

bottom mount will be a single piece, holding both cavities together.

I'll add a top plate to hold the shield and cavity later.

 

Note: I'm thinking about using teflon to make all the mounting pieces (top and bottom) so the mount will act as heat insulation between the shield and the platform.
