1. Proton Improvement Plan Keith Gollwitzer January 5th, 2015 All Experimenters’ Meeting 11/5/2015Gollwitzer AEM

2. 21/5/2015Gollwitzer AEM PIP Objective Updated Develop a plan to increase Proton Source throughput while maintain good availability and acceptable residual activation. The plan must address hardware modifications to increase repetition rate and improve beam loss while ensuring viable operation of the Linac through 2023 and Booster through 2030 Goals for the Linac and Booster to deliver 2.25E17 protons per hour (15 Hz) while maintaining availability > 85%; residual activation @ acceptable levels and ensuring a useful operation life.

3. Linac 200 MHz RF Power System 5MW pulsed Single Beam Klystron to operate at 201 MHz for use as the power source for the DTL Linac (could replace 7835 tube system) – Monitoring the production of the Klystron Working out details about final testing Manufacturing to be finished in September Upgrade of Modulator – Designing Control Card – 25-cell prototype work continues 31/5/2015Gollwitzer AEM

4. Linac Notch Goal is neutralize beam in RFQ Injector Line to create gap in beam needed in Booster for extraction – An 80ns gap every 2.22μs for the length of multi-turn Booster injection 27-35μs Optical ports and mirror installed during last shutdown Moving laser system components from test lab to optical box next to Linac Installing optical shielding for safe laser light transport Working with timing signals to work within accelerator control system Hope to be able to test later this week 1/5/2015Gollwitzer AEM4 Assembly at lab area Assembly installed RIL

5. 5 Cavity refurbishment Vacuum Water Contact Fragile! ALARA From M Slabaugh (AD MSD) 1/5/2015Gollwitzer AEM

6. 6 Cavity refurbishment Surfaces are now uniform and parallel Known distances between surfaces We are adding landmarks on cavity body. Before testing, metrology measures/references the outside landmarks with respect to the interior beam pipe. This allows quicker alignment of cavity in the tunnel. 1/5/2015Gollwitzer AEM

7. 7 Tuner refurbishment Badly damaged cone fingers Clamp-stem connects tuner’s 2 cones’ fingers electrically to cavity From M Slabaugh (AD MSD) 1/5/2015Gollwitzer AEM

8. 8 Tuner refurbishment Cones- 10 step process TD supporting work From M Slabaugh (AD MSD) 1/5/2015Gollwitzer AEM

9. 1/5/20159Gollwitzer AEM Goal is to have 17 installed prior to shutdown

10. New Tuners Many issues with any vendor able to produce ferrite cores of the correct magnetic permeability for our application Just received a partial shipment of cores which appear to satisfy our requirements – We are doing QA for acceptance Technical Division will build new tuners with these cores These new tuners will speed up the refurbishment process 1/5/2015Gollwitzer AEM10

11. Other PIP Booster Work West gallery bias supply upgrades continue East gallery RF system testing of 15 Hz operation has been sporadic Planning to repurpose two un-used cavities to make two more RF stations Cogging work is addressing problems with bucket jitter Damper studies continue Beam Position Monitor system is being designed TLM tunnel hardware installed Collimation studies to start Working on design of a harmonic cavity Next shutdown preparations continue – Replacement of electrical transformer – Replacement of RF system anode supplies – Continuation of replacement of old vacuum components – Addition of 20 th RF station 1/5/2015Gollwitzer AEM11
