SAD and Summer Run Schedule

• Today through summer run
• Steve's SAD calendar - https://accweb.acc.jlab.org/calendar/
• List of ATLIS tasks - https://wiki.jlab.org/ciswiki/index.php/Spring_SAD_2019

Pre-Beam Jobs

• PQB screen shots of control screens - https://logbooks.jlab.org/entry/3681125
• Laser configuration (ABCD)
• Helicity board configuration
• PQB laser configuration
• Activate photocathode & QE scan
• Configure for anode bias

Beam Jobs to FC#1

• Pick all save for restoration, move to new spot, restore orbit
• Set photocathode rotation (few access to roll puck, then PQB measurement to where? to finalize orientation)
• Study and then fix anode bias for 0V, 500V, 1000V (TOF using chopper, beam size or emittance scan using solenoids)
• ABC transmission setup w/ which? flipper choice (either makes transverse polarization) + HWien ~ 16 deg.
• What PQB beam measurements to make?

Beam Jobs to FC#2

• Initial restoration to FC#2
• Carry on w/ ABC setup (finalize flipper choice here, maybe?)
• Mott measurement to precisely finalize spin rotators (VWien and Solenoids)
• Iterate w/ ABC setup, to FC#2
• What PQB beam measurements to FC2 (can be high current)

Beam Jobs to ILD, and beyond...

• Initial restoration to ILD
• Scaling RF and injector magnets, energy/injector beam setup
• Complete ABC setup to ILD
• M56/PQB measurement to ILD?

Beam to Halls

• What is prioritize/sequence for jobs, e.g. when does spin dance happen?

Punchlist

• FC2 air cylinder needs to be replaced
• Regular RTP rise time procedure (how often?, as-is manual or automated?)
• Insertable lens (is alarm sufficient, or disconnect IN/OUT control?)
