[clas12_rgk] [EXTERNAL] Re: CLAS12 scheduling for FY21 and FY22 - REMINDER -

Thu Sep 12 02:20:28 EDT 2019

Dear Marco,

please find in attachment the updated summary for RGK , with two 
corrections suggested by RG-K spokespersons:

- the number of minimal PAC running days has been  increased from 20 to 
22, to take into account the effective charge on target instead of the 
available beam time to obtain at least half of the expected statistics;

- Maxime Defurne has been added as co-spokesperson for the DVCS 
experiment at 6.6 GeV and 8.8 GeV.

Thank you for your understanding

All the best

Annalisa
