[Dsg-rich] Temporary dark box for RICH cosmic tests

[Valery Kubarovsky]

Hi All,

The thickness of the box is not an issue. We are going to work with cosmic muons. These particles can penetrate even steel wall. It has to be rigid and light-blocking. The light is very -very important. 

Regards,
Valery
