AGS & Booster Modifications for RSVP

1. AGS & Booster Modifications for RSVP Kevin A. Brown C-AD kbrown@bnl.gov

2. Overview of Basic Areas Requiring Improvements • Categories of Improvements and Modifications • Ensure RSVP has no impact on RHIC and NASA operations • Minimize occupational dose received by workers • Minimize environmental impact of RSVP operations • Reduce the risk of equipment failure • Reduce the risk of fire or electrocution • Achieve RSVP Intensity/Throughput goals • RSVP Modifications • General Areas of Improvements and Modifications • Ground water protection by capping soil-shielding over tunnels • Cables and Cable trays • Radiation damaged magnet coils • Obsolete Controls • Aging and radiation damaged equipment and instrumentation • Upgrades to achieve intensity goals • Modifications for RSVP (bunched beam slow extraction) Kevin Brown, BNL

3. Requirements • Accelerators must not be activated beyond what is maintainable by people (as low as reasonably achievable {ALARA}) • Booster • ions to the NASA Space Radiation Laboratory (NSRL) • ions to the AGS • polarized protons to the AGS • high intensity protons to the AGS – must not impact others • AGS • ions to RHIC • ions to NASA • polarized protons to RHIC • high intensity protons to RSVP – must not impact others • Switchyard • high intensity protons to RSVP • ions to a high energy NASA Space Radiation facility Kevin Brown, BNL

4. Basic Infrastructure Modifications • Electrical Modifications • Cable repairs and replacement • upgrade of kicker Pulse Forming Network’s (PFN) • Purchase 6 sets of Booster dipole magnet coils, repair one magnet • Replace 8 sets of magnet coils around AGS extraction septa magnets • Mechanical Modifications • Build a spare Booster extraction septum magnet • AGS RC networks upgrade for high current beams • Instrumentation • Upgrade & repair loss monitor systems • High beam current wall monitors • remote gain control on Booster To AGS instrumentation • repair and upgrade AGS ring grounds monitor systems • Controls • replace obsolete hardware and support modifications Kevin Brown, BNL

5. Booster Modifications • Booster Injection • C5 and C7 magnet coil protection • LTB collimation to reduce losses on C5 and C7 • Collimation system • Reduce activation of components by concentrating losses on dump • Fast RF Feedback • greater stability and improved beam loading compensation for High Intensity • Heavy Ion Inflector Protection • Prevent damage to inflector from High Intensity Protons Kevin Brown, BNL

6. AGS Modifications • Active Filter – spill structure • Thin Septum Power Supply • Thick Septum Power Supply • Dump Bump Power Supply – spill structure • New Extraction Septa - acceptance of extraction channel • Sextupole Coils • Collimators - control losses • Impedance reduction - high intensity instabilities • Motion systems upgrades - damaged and obsolete • Video Systems - radiation damaged • AC Dipole - MECO extinction • Strip-line Kickers - MECO extinction • AGS injection kickers - higher intensity • 25 MHz RF Cavity - KOPIO bunch widths • 100 MHz RF Cavity - KOPIO bunch widths Kevin Brown, BNL

7. CFI Collaboration • The costs associated with the AGS upgrade for KOPIO are partly being covered by the Canadian collaboration. • 25 MHz and 100 MHz micro-bunching radio frequency cavities • A5 kicker magnet upgrades (+A10 modules) • Beam and accelerator physics studies (+simulations) • KOPIO beam line and production target • AGS upgrades for KOPIO – overall budget (2001 $’s).
