[Dsg-rich] progress of RICH mirror support system?

[Tomassini Sandro]

Dear Bob,
me and Dario are at Jlab until March 25th, if you need any explanation 
for the mirror mounts you received please let me know.

For the Adhesive, especially for the interface PEEK-CFRP, we do not have 
any real experience.
What I can tell you is that during the fabrication of the RICH shell the 
company we selected has extensively used the following compound 
(Hysol_EA_934NA) to bond all the interfaces CFRP-CFRP or CFRP-Metal.

I cannot garantee that this compound is good for your interface and I do 
not have relaible data concerning the  radiation strength, I think you 
should double check it with the producer.

I think the lesson you learned in the LHCb mirror production, since it 
is still there, is unique.

For any doubt do not hesitate to contact me

Regards

Sandro
