Task View (Internal): http://opsweb/gantt/2019_Fall/fall2019Run-tasks.html

Plans and Status rest of SAD

• Oct 7 - 11 : Gun bake, leak check, lasers ready, laser retro, laser training, laser PQB start
• Oct 14 - 18 : laser PQB continues, Re-assemble instrumentation, HV cables, coordinate with PSS/Ops for HV ON, conditioning?
• Oct 21 - 25 : Make a photocathode, remove SF6 conditioning resistor, crane stuff out, clean up, start making beam w/ PQB checks
• Oct 28 - Nov 1 : Injector setup and PQB checkout

What fit's and doesn't

• I don't think we have time for the Load chamber, little time
• Daniel will coordinate removing the big HVPS oil tank

CREX jobs

• Laser Room

Camera measurements (post fiber change)

Spinning LP for A/B/C/D: http://opsweb.acc.jlab.org/CSUEApps/atlis/task/19669

Transition Time recheck

IA setting zero-finding

• Beam to FC#1

Cathode Rotation: http://opsweb.acc.jlab.org/CSUEApps/atlis/task/18799

IA/RTP/RWHP settings for all 4 lasers: http://opsweb.acc.jlab.org/CSUEApps/atlis/task/19670

Pos Diff Feedback to FC1/FC2: http://opsweb.acc.jlab.org/CSUEApps/atlis/task/18793

• Beam to either FC2/ILD (end of injector)

90Hz beam motion fix?

PQB Health check to FC2

PQB Health check to ILD

• Beam to HallA

Adiabatic Damping check?

Dithering check?

• During Experiments (affects other halls, but also necessary for HallC to ensure we are minimizing their Aq well)

PITA scans

RHWP sweeps

• Post Experiment

Spot size asymmetry measurements: http://opsweb.acc.jlab.org/CSUEApps/atlis/task/19669

LERF

Nov 1-4 HCO for isotope run (laser, photocathode, high voltage)

Nov 5-6 : 2 shifts/day commissioning run, ~60 pC @ 4 MHz, < 1 mA

Dec TBD : another couple shifts, actual isotope run, ~60 pC @ 4 MHz < 1 mA

UITF

• Electrode choice
• Tentative dates for Booster commissioning
• Wien filter testing
• HD Ice run
