3. Linac

4.  Modulator Upgrade  35kV, Marx-topology modulator  Progress made on various fronts  Enclosure design complete and near delivery  Gate driver circuit board design/layout done  Short circuit testing continues  Successful design and tests, with available end-of-year funds procure the long-lead items for the full voltage modulator PIP - Linac 200 MHz RF Power System F.G. Garcia AEM - PIP Report 10/06/2014  HLRF – SBK201  Successful CDR review early July  Focus now shifted to drafting & purchase of long-lead items

5. PIP - Linac Accelerator Physics  Laser Notch  Internal review carried out early August  Readiness for vacuum cavity / optical cavity installation during shutdown F.G. Garcia AEM - PIP Report 10/06/2014 Laser port Assembly at lab area Assembly installed RIL beam

6. PIP - Linac Utilities  Power distribution (Dec’11-Sept’14)  L1 transformer fully installed  13.8kV to 480Y/277V  Better heat loss (80C vs 115C)  Low voltage breakers, trip control and instr.  What will become of the removed equipment?  Transformer will be kept as spare for Linac  additional 2 other old-style transformers in use  Breakers & primary switch will be rebuilt and tested – spares L4 task complete! F.G. Garcia AEM - PIP Report 10/06/2014 July’14 Sept 17 ‘14 Sept 24 ‘14 Original L1 sub-station

7. PIP - Linac Utilities  LCW system  Dual temp. system  Replace cooling provided by EOL DTW piping and fan coil units to a rooftop AC unit  Contract awarded and pre-meeting conducted  Gallery work starts Oct10 th  CUB 55 LCW backup pump  Extensive delay  Overran in costs forced the project to be restructure to a FP rather T&M  Process complete in time for the shutdown  Job still has not started!  Vacuum upgrade  Turbo pumps (shutdown’14)  Original pumps in service since day-one  Belt driven / oil reservoir  Heavy, big, replacement parts no longer available  New pumps are sealed clean bearings, compact, high speed, freq. drive control L4 task complete! F.G. Garcia AEM - PIP Report 10/06/2014

8. Booster

9. PIP - Booster RF Anode & Bias Supplies  Anode Supplies  Goal: install both supplies during shutdown 2014  Delays in the delivery of long lead items prevented this task to be complete  AD/EE continue to make progress with assembly  Supplies may be built but not tested by the end of the shutdown  Await for opportunistic shutdown next year to install F.G. Garcia AEM - PIP Report 10/06/2014  Bias Supplies  Scope of work: Replace transformers, re-plumbing and re-wiring for 15 Hz operation Current Situation East gallery: 100% complete West gallery: 10% complete

10. PIP - Booster RF Cavity & Tuner Refurbishment  Work progressing well with the cavity refurbishment  Scope of work: refurbish all 19 cavities in Booster  Up to now, 11 cavities fully refurbished and re-installed in tunnel  Additional cavity (#20) installed prior the shutdown  Cavity built from leftover parts F.G. Garcia AEM - PIP Report 10/06/2014 Current Situation  Cones are bottleneck  Time consuming to rework a used cone 10 step process

11. PIP - Booster Notch system  Scope of Work: Reconfigure and replace notch kickers & corresponding high voltage system for faster rise/fall time F.G. Garcia AEM - PIP Report 10/06/2014 Short kickers beam 3 bucket notch Current Situation  Complete installation of  6 “short” kicker magnets & corresponding high voltage system  redesigned S12 spool piece  improve aperture at downstream of notch kickers (~10%)  standard Booster BPM’s pickup plates proved to be aperture restriction

12. PIP - Booster Radiation Shielding  Scope of Work: Revised Booster shielding assessment to allow high intensity operations.  Present SAD allows for 1.8E17 p/hr  Above ground radiation protection  Practical limit determined by the array of detectors spread around the ring  50+ interlocked detectors placed above ground at specific locations covering all loss points  Tunnel radiation protection  Overall loss rate limited by the “watt meter” – 525W &  Local control loss possible with array of 60+ BLMs along the tunnel  During the shutdown, 8 TLM’s installed in Booster tunnel  High loss points: Injection, extraction, collimator, notch regions  Beam tests to characterize system F.G. Garcia AEM - PIP Report 10/06/2014

13. PIP - Booster Utilities  Power distribution  Transformers  First transformer replaced 09/27 (west side)  Problems with the breaker will prevent the installation on the east side this shutdown F.G. Garcia AEM - PIP Report 10/06/2014  Vacuum upgrades  Turbo pumps  All pumps on-hand  Auxiliary cables and relay rack work moving along  Pump installation progressing well  Unlikely to complete this shutdown BWG - transformer

14. PIP PIP-II adjustments F.G. Garcia AEM - PIP Report 10/06/2014 Meetings and discussions began to adjust PIP to PIP-II

15. PIP - Conclusions  PIP continues to make positive progress towards its goals  Linac  Lots of progress made on the 200 MHz RF system  First step completion of R&D project to create a notch within linac beam pulse using laser system  Completion of two L4 tasks during shutdown 2014  Vacuum system  Power Distribution  Booster  >50% cavities refurbishment complete  Complete installation of BW house transformer  Setup complete for TLM’s beam tests run  Complete installation of short kicker magnets for notch creation  PIP plan adjustments for PIP-II  Discussions started between PIP and PIP-II to redirect and modify existing PIP activities to line up with PIP-II program F.G.
