2015-09-22 m1 optics discussion¶

16.30 UK time, POD or http://mice.iit.edu/phonebridge.html

0. Finish outstanding optics studies + optimisation routines (Rogers)
1. Investigate optics settings for "Hold SSU at 4T, degrade only SSD" etc (Rogers)
1a. Investigate optics settings for "Use E1 as a match coil" (Rogers)
1b. Investigate optics settings for "FocusCoil_US is not the same as FocusCoil_DS" (Rogers)
1c. How bad are non-linearities/emittance growth if we are just TRP to TRP, do we really need beta = const in tracker region? (Rogers)
2. Send Ryan some currents and beams settings to look at MC of "asymmetric" setting (Rogers)
3. Run MC (Bayes/Liu)
4. Look at tracker resolution vs Bz (Bayes/Liu)
5. Look at Demo options (Pasternak/Lagrange)
6. Validate optics study (Blackmore)

Notes¶

Ryan Bayes

• See slides
• Note momentum spread is 25 MeV/c RMS
• Note transmission cuts/etc are missing - needs some cleanup
• Plots that Ryan presented are generated using personal C script

Ao Liu

• Changed dp/p to 0.01; simulated data for the modes as specified; needs to look at analysis/plotting emittances etc
