[Dsg-rich] reflectometer test for the RICH mirrors.

[Amrit Yegneswaran]

0800 hrs tomorrow sounds good nick. 
marco would like to use first a test sample before he uses the real mirror. 
this sample is small enough that it should work with the pump fixture. 
we also have two large black fabrics, which mindy found and is using. 
have you got any simple ray trace diagrams that you could e-mail us

I would say it makes more sense to meet tomorrow morning (I can be there around 8). 
This way we can set everything up and start measurements right away. 
If you have found the way to hold the mirror within the box, the only problem I see is the cloth - it is used in the HTCC PMT testing setup now. 
The black box in the EEL108 can not be run without some cover over it, I found few holes in the walls and door. If you can find something by tomorrow we can start. 
Nick.

hi nick, 
thanks for the prompt response. 
could you come over closer to 1500 hrs, as mindy leaves at 1530 hrs. 
in any case, amanda and marco will be here at least up tp 1730hrs 
also, could you meet with us briefly tomorrow morning (mindy is here at 0630 hrs), when you get in to check if everything has been set up correctly. 
do let marco and amanda know. 
sincerely 
amrit

peter has setup the software system (monochromator and the labView program) 
so if mauri/nick or both came over for about 15 - 30 mins to explain the setup, mindy can start with the measurements. 
please let marco and dsg know how soon you can come over. 
also, do you know what happened to the black cloth which we used to drape over the black box.
