Dear All,

On Friday September 1st before midnight RICH group started to take 
cosmic data with 32  tiles (96 MAPMTs, 64 pixels each) completely 
equipped with front-end electronics. So in total we have 6144 RICH 
channels. The trigger is using information from two trigger RICH tiles 
and two scintillator counters. Please take a look to the attached plots.
You can find more pictures with Cherenkov rings and experimental 
equipment in

https://userweb.jlab.org/~vpk/RICH12/2017_09_05%20RICH_96/

The signal in the center of the ring is coming from the muon hitting the 
front face of the MAPMT.
It has many pixels fired.
DAQ and front-end are working very stable.
A lot of people and groups are participating in this project. Many 
thanks to all of them!

Regards,
Valery
