LiH empty prioritisation¶

I list below the prioritisation of different settings; I would need to coordinate with Colin to decide how many settings to take - some may drop off the end, depending on the available time. I note that some of the cooling channel tags got tagged differently in the CDB - I will update with the correct CDB tag ASAP.

Solenoid mode¶

For solenoid mode, the prioritization is - we take our best setting, which is at 140 MeV/c; then we try for a different optics at 140 MeV/c (next best setting); then we try to move off momentum; then we try a couple of different 140 MeV/c optics. I would take all the solenoid mode data in one blob, to avoid the moderately risky "polarity change" operation and to increase the amount of time for data taking.

2017-02-6	M2D on	2T in SSD	140 MeV/c	it is our best setting
2016/04 1.2	M2D off	3T in SSD	140 MeV/c	it is our next best setting, with a bit different optics
2016/04 2.3	M2D off	3T in SSD	200 MeV/c	moving off momentum
2016/04 2.4	M2D off	3T in SSD	240 MeV/c	moving further off momentum
2016/04 1.3	M2D off	3T in SSD	140 MeV/c	less focussing
2016/04 1.5	M2D off	3T in SSD	140 MeV/c	more focussing

Flip mode¶

2017-02-7	M2D on	2T in SSD	140 MeV/c	it is our best setting
2017-02-8	M2D on	3T in SSD	170 MeV/c	move off momentum
2016-05-1	M2D off	3T in SSD	140 MeV/c	next best LiH setting
2016-05-2	M2D off	3T in SSD	140 MeV/c	next best LiH setting
