Booster/AGS Infrastructure

• All systems required for high intensity protons
  are being reviewed.
• Components identified include all levels of
  infrastructure, from cable trays to beam
  instrumentation.
• While the machines are cool, there will be
  pre-emptive replacement of components that are
  known will become activated.
• Components NOT identified are those things
  already included in the RSVP WBS structures that
  are experiment specific and not considered part
  of C-AD core competencies.
• Some items identified are general infrastructure
  (not specific to high intensity operation, but
  important for any program) and as a result RSVP
  covers only part of the burden.
• Some real improvements are included. These are
  things that are deemed important for achieving
  the goals of RSVP and/or improving accelerator
  efficiencies.

Requirements

• Ions to RHIC
• Ions to NSRL
• Polarized Protons
• G-2 and E949 ?
• High Intensity Protons for RSVP
• The AGS and the Booster cannot be activated
  beyond what is maintainable by C-AD personnel.
• RSVP operations will not impact RHIC operations.
• ALARA

Booster/Linac

• Cable Trays
• Old, damaged, and radiation damaged cable
• Damaged magnet coils
• Booster Main Magnet phase shifting transformers
• Main Magnet ripple for bunch merging
• Injection vacuum chamber (beam losses due to
  injection)
• Wide band RF system upgrade for RF feedback
• Spare Extraction septum (F6)
• Instrumentation Loss monitors, Inflector
  Protection, LTB, BTA, BPM switching, wall current
  monitor, stripping foil drive, cables
• Controls eliminate Obsolete, unserviceable
  controls
• Linac ion source new controls

AGS

• Cable trays
• Old, damaged, and radiation damaged cable
• Damaged magnet coils
• Main Magnet rectifier transformers
• Main Magnet active filter (slow extraction)
• J10 Dump bump power supply (low ripple, for
  extraction)
• New power supplies for extraction septa
• Upgrade for Booster extraction and AGS injection
  kicker pulse forming networks.
• RC networks and ring grounds monitoring
• New extraction septa (H20, F5, F10) plus spares
• Instrumentation long loss monitors, current
  transformer, wall current monitor, video, cables
• Controls eliminate Obsolete, unserviceable
  controls

Switchyard

• New Switchyard with no beam splits and no
  elevation shifts.
• NASA relocation
• Vacuum upgrade
• Beam plugs for safely off switches
• Collimators for halo cleaning and extinction
• Upgrade Access controls
• Instrumentation rack relocations, loss monitors,
  video, motion systems, profile monitors,
  intensity monitors
• Controls eliminate Obsolete, unserviceable
  controls

Beam Lines

• Beam lines are included with the
  philosophy that C-AD works under a single work
  structure for all conventional accelerator
  components. Components which do not explicitly
  fall under the C-AD core set of competencies and
  are experiment specific remain under the
  experiment work structures.
• Removal of old beam line infrastructure
• Shielding modifications
• Vacuum and beam line elements
• Power supplies repair and upgrades
• Services
• Access Controls
• Instrumentation loss monitors, video,
  profile/position monitors, intensity monitors,
  target monitors, Target and solenoid protection
• Controls eliminate Obsolete, unserviceable
  controls

Summary

• Infrastructure improvements needed to run
  RSVP experiments have been evaluated. We cannot
  claim to have covered all the bases. There are
  bound to be things which we cannot anticipate or
  perhaps have even missed in our evaluation.
• The process of the cost estimation is still
  on-going and we are far from finished. Still to
  be done are
• Calculation of in-directs
• Calculation of contingencies
• Evaluation of schedule and timelines
• Final evaluation of priorities and allocations.
