Dear Amrit, 

This time I will be leading the effort of fall run in Hall B Sc-magnets. In view of that, I will need help from DSG group starting Monday next week. This is in order to carry out a few post cool-down tests at lower current in order to evaluate the modifications carried out during last a few weeks on solenoid and torus in Hall B. I will also like to give an opportunity to Krister (Hall B engg) to learn the procedure that is normally followed by DSG and ask questions. 

The test procedure that was established and carried out by Tyler, Brian and Pablo in the past and continued doing now is excellent. 
I am looking forward to an assigned name/s from DSG for next week post cool down check outs. 

Please suggest and will coordinate the same with the respective people. 

Sarin - will also need your support, in case we struggle with the newly installed E-stops. 

Thanks in advance. 

Regards 

Probir

Hi Ruben, 

I talked to Krister, he can support this effort unless it interferes 
with preparations for the Fall run. He estimates a few days, which will 
fit into his schedule. 

Regards, 

Bob
