OngoingComplete

3 L2 tasks 9 L3 tasks31 L4 tasks 30% Linac

70% Booster

Linac

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

PIP - Linac Accelerator Physics Laser Notch

Internal review carried out early August Readiness for vacuum cavity / optical cavity

installation during shutdown

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

Original L1 sub-station

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 Oct10th

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

Booster

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 SituationEast gallery: 100% completeWest gallery: 10% complete

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

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

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

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

PIP PIP-II adjustments

F.G. Garcia AEM - PIP Report 10/06/2014

Meetings and discussionsbegan to adjust PIP to PIP-II

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 programF.G. Garcia AEM - PIP Report 10/06/2014
