1. All Experimenters Meeting PIP Report Fernanda G. Garcia on behalf of PIP team 07/01/2013

2. RFQ Injector Line (RIL)

3. RIL Highlights – Thin corrector  Large exit angle  Correctors are running with high current, predominant vertically, at the downstream end of RFQ in order to maximize beam transmission  Thanks to BNL for the design and FNAL/TD for building the correctors  Corrector installed early June  Modest gain in beam current  Increased extractor voltage by 1.5kV  Yielded 11% more beam at entrance of Linac F.G. Garcia AEM - PIP Report 07/01/2013 Thin corrector Contribution: C.Y. Tan

4. RIL Highlights – Source Swap F.G. Garcia AEM - PIP Report 07/01/2013  FNAL/RIL design posses two sources located side-by-side on a slide platform to allow for easy and quick swap  First swap: June 17  Duration: ~ 7 hrs  Second swap: June 26  Duration: ~1hr Contribution: D. Bollinger

5. PIP – Linac Activities

6. Linac 200 MHz RF Power System  Modulator Upgrade  35kV, Marx-topology modulator to drive triode (or MBK)  SLAC – Two cell test stand  Simulate the ripple due for 2 cells both in phase (11%) and out of phase (0.9%)  Compare 2 cell out-of-phase simulated to measured ripple (1.1%)  Determine via simulation the ripple for 5 vernier cells (0.23%) F.G. Garcia AEM - PIP Report 07/01/2013

7.  Modulator Upgrade (cont.)  35kV, Marx-topology modulator to drive triode (or MBK)  AD/EE – Working on building 9 cell Marx Modulator  Able to create any arbitrary wave shape, from trapezoid to square  In the future: determine rising and falling edge ripple  Built prototype discrete control system  Testing second prototype Marx cell  under normal load conditions (350 Amps)  under short circuit (2000 Amps)  Continue fabrication of 9 cell Marx Modulator Linac 200 MHz RF Power System F.G.

11. PIP – Booster Activities

12. Booster Utilities Old Y-BE2 40+years old – beyond expected lifetime Oil-cooled transformer Questionable operation conditions for quite a while o May/2012 investigation revealed noisy current output, over temperature operation conditions… Replaced with “old spare” ~ 1 year ago F.G. Garcia AEM - PIP Report 07/01/2013 New Y-BE2 Installed May 17-18, 2013 Air-cooled transformer Remotely monitor & control Breakers are modular (smaller spare inventory) Improved monitoring (access to currents, voltages, harmonics )

13. Booster  Booster shielding assessment  Studies concerning beam loss profile and radiation measurement through penetrations were done  Discussions and data analysis underway  Booster Notcher  Progress with time in and commissioning F.G. Garcia AEM - PIP Report 07/01/2013 6 4.5 3 1.5 0 E12 12T - $17 6 4.5 3 1.5 0 E12 12T - $17

14. Booster RF system  Cavities Refurbishment  7 of 19 cavities have been refurbished BRF 1,3,5,6,7,8,15  BRF11 has issues with heating on the tuners  Need to be re-addressed for 15 Hz operations F.G. Garcia AEM - PIP Report 07/01/2013 Booster Cavity Work Refurbished (15Hz) SS Prototype SS Upgraded Cavity Removed Stats: Last refurbishment : 9.4 weeks last 3 cav. : 10.5 weeks Courtesy: K. Gollwitzer
