[clas12_rgk] [EXTERNAL] Re: SAMPA test in RGK

[Annalisa D'Angelo]

Dear Yuri, dear All,

on behalf of RG-K we can certainly schedule a test of the SAMPA chip 
readout electronics during RG-K but we would rather do it at the end of 
RG-K, reserving for you the time you need for the electronic read-out 
swap and the test.

We do not like the idea of changing the MVT electronics twice during the 
run, because we always risk a modification of the set-up which would 
require a dedicated alignment, calibration epochs, possible cable swaps etc.

The swap back to the DREAM read-out could be done during the change to RG-E.

Would this work for you?

All the best

Annalisa
