PIP Report
F.G. Garcia AEM - PIP Report 10/06/2014
OngoingComplete
3 L2 tasks 9 L3 tasks31 L4 tasks 30% Linac
70% Booster
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
F.G. Garcia AEM - PIP Report 10/06/2014
Laser port
Assembly at lab area Assembly installed RIL
beam
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
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
F.G. Garcia AEM - PIP Report 10/06/2014
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
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
