## Change in Debuncher Orbit

## Change in AP2 Stacking Orbit

## Commissioned

- Deb Rev Prot TBT
- Deb Rev Prot partial turn extract up AP2
- Deb Component Centering
- Deb Orbit-Quad offset
- AP2 Orbit-Quad offset
- AP2 Beam Line Correction
- One-Shots for getting Deb beam
- Admittance measurement from datalogger
- “Deb Heat Rev p’s to AP2” aggregate
- AP2-Deb Injection Region setup
- Auto-tune 120 GeV orbit of P1-P2-AP1
- New detuning of DRF1 Rotators (attempted)

- Application
- Procedure

## Obligatory Pretty Pictures

## Accomplishments

- Lattice measurements for Debuncher and AP2
- Determine Debuncher Orbit/BPM-Quad offsets
- Corrected Debuncher Vertical Orbit to Quad Centers
- Centered Debuncher Components about orbit
- Determine AP2 Orbit/BPM-Quad offsets
- Set Orbit, Stands and Settings for AP2-Debuncher Injection Region
- Corrected AP2 Orbit to near Quad Centers
- Installed AP2 lattice that matches to Debuncher Lattice

- 1⁄2 done; more yet to do to finish

## The Still Big Confusions

- AP2 Orbit dependent upon *partial turn* in Debuncher or from *extracting circulating beam*
- Does it matter anymore since we did the following:
- Corrected relative D/A kicker timing for Rev Prot
- Control ARF1 from putting niblet on beam
- Were able to run continuously at 10sec (7 bunches)
- The losses in AP50 during stacking
- More secondaries ?
- Better orbit to be found?

## Short Term Items to be Done

- AP2 auto-tune; tweaking new auto-tune(s)
- AP2 SEMs & SEM403 with new AP2 lattice
- Check of Deb Longitudinal Cooling
- Production Rate as function of beam on target and stacking cycle length
- Check of lens steering

## “Next Time” Items

- Correct Debuncher Horizontal Orbit
- Install new Debuncher Lattice
- Center Debuncher Components
- Install matched AP2 Lattice
- Remove Lens Steering
- Steer AP2 on apertures
- D/A Orbit
- Accumulator Orbit and Aperture

## Other Items Done

- Replace Lens
- Installed Collimator in target station
- Survey of AP2-Debuncher Injection Region
- Ramping Devices in AP1
- Debuncher IPM signals
- 2.5MHz noise in AP30 found as problem for 2.5MHz mode of new AP3 BPMs
- D/A Beam Based Alignment
- Accumulator orbit/aperture
- Stacking tune-up
- Probably missed a lot

## The Pickups understood finally

- Had drawn ellipse for aperture
- to fit within pickups
- Turns of “closed pipe” at down-
- stream end...BAD
- Only found this drawing this month
