## Antiproton source Nov 2004 startup plan, 2nd draft.    

Nov 11: secure for pbar safety systems test
Nov 20: MI beam?  (call this day 0)

Days -2,-1: pre-startup power-on

Check out buses, vacuum, pulsed devices, RF, cooling amplifiers
Check that new stuff powers up, can be properly controlled:
D4Q4 LQBs, D:ISEP, D:IKIK stand, DRF2, VT108(AP1)
quad shunts: 716, 717, 719, 720, 722, 723, 724, 732, (gerry dugan’s shunt moves?)
power supplies: A:SS106, D:H926
Motorized quad stands
111, 117, 200, 202, 214, 217, 306, 309, 312, 317, 400, 414, 417, 506, 509, 512, 517, 600, 617
Restore D1 saved settings; enable alarms

Days 0,1,2: reverse protons

Establish 8 GeV protons down P1, P2, AP1, AP3; tune for decent efficiency
Circulate reverse protons in accumulator
Accumulator admittances, orbits, tunes (vs dp/p), lifetime
80% of 6.5/7.3/7.5 x 8.1/7.9/6.3 (inj/cen/core meas 3/04) before continuing
Ramp to shot lattice; measure tunes (spectrograph) and orbit
Send ARF4 through unstacking motions
Circulate reverse protons in debuncher
Make sure swapped (?) A:ISEP1 works
Debuncher admittances, tunes, orbit, lifetime
Aim for 20 x 15 (80% of 26 x 18) before stacking
Reverse protons up AP2: check toroids, SEMs, (BPMs?)
make sure new D:ISEP works
track intensity all the way up AP2??

## Day 3: antiprotons to debuncher

Establish 120 GeV protons down AP1 (beamline losses, orbits)
Targeting tune-up issues?
Antiprotons to debuncher
use TBT: D:ISEP, IKIK working OK?
Check/tune bunch rotation
longitudinal schottky
Check/tune debuncher cooling
longitudinal schottky, free run SA
use H,V schottky signals to watch betatron sidebands shrink?
Standard phase adjustments?

## Days 4,5,6: stacking

Send antiprotons to accumulator
if everything works, 79MHz schottky should suffice to see them
Check ARF1, stacktail working
Stack.  Production rate OK?
Check/tune all accumulator cooling
Dampers and ARF2 working?

Day 7: test shots

Check ramp to shot lattice (tunes)
Check RF unstacking
shoot to MI
Emittance of extracted bunches OK?

## After stacking is established

Measure standard performance benchmarks; make improvements where needed
TOR109, IC728, INJFLX, D:YIELDI, bunch length & phase w.r.t. RF
bunch rotation efficiency, D to A efficiency, injection to deposition efficiency
debuncher L,H,V cooling rates; stacktail clearing rate
accumulator cooling benchmarks?
Efficiencies & emittances for antiprotons to MI?
Follow up on shutdown work:
new motorized quad stands: easy aperture gains?
debuncher injection region
More measurements (if time)
Debuncher cooling vs time in cycle (calibrate with scrapers)
D to A efficiency vs cooling time
get good measurements of both turn-on and asymptote
effect of momentum cooling on/off?
