[Clas12_rich] CMM for measuring RICH mirrors during week of 6/13/2016

[Tyler Lemon]

Dear Chris and Jim,

Would the 60 um CMM be available for measuring the RICH mirrors some time Tuesday June 14 through Friday June 17?

As mentioned in my previous email on 5/25, there would be four, square spherical-mirror segments with the largest being about 840mm by 530mm with a radius of curvature of 2.71 meters.

Would the CMM be able to take measurements of the entire mirror segment without having to be reset? Also, who would perform the measurements? Could the DSG use the CMM or would Survey Group have to perform the measurements? Please let us know.

Best regards,
