## Notes on beam test (Elton)
## Beam test  
##* Tim: Can safely remove the DIRC with the B field on.  Time estimate is about one shift.
##* No easy way of inserting additional Pb sheets next to the TOF. Possibly one can mount Pb sheets off the DIRC support structure.
## Test activities (email 5/21 from Ilya)
##*  I believe we need to collect similar dataset as we did before without DIRC: high-frequency random trigger, possibly shifted down coherent peak, LH2 and empty target, beam current 10, 20, 30 nA ~3 min each.
##* If it would be possible to install single thickness shielding without modifying TOF position from the nominal value - also the same dataset with the shielding installed (inner hole in the shielding needs to be increased in this case).
##*  In case if shielding installation requires modification of the TOF position, I think it is more important to keep the right TOF position rather than to collect additional data with shielding installed.
