  1. Upgrading 600L/s IPPS Gustavo Alverio University of Central Florida August 5, 2003

  2. Introduction • Ion pump power supplies (IPPS) are located in booster gallery • Supply power to 600 L/s ion pumps located in booster ring • Old IPPS were inaccurate and poorly efficient • Modified IPPS are more productive and accurate • The modification of the IPPS will pave the way for greater vacuum, thus better quality beam

  3. Ion Pumps • About 80 pumps located around booster beam • Absorb ions in vacuum tube • Pump contains plates • Supplied voltage charges plates • Ions are attracted to charged plates, and stick onto the plates • With less ions and a better vacuum, beam is of better quality

  4. Ion Pumps cont’d Ultek 600L/s Ion pump Operation life is 40,000 hours at 10E-6 torr

  5. IPPS • IPPS are located around booster gallery • One IPPS controls one ion pump • Delivers voltage to the ion pump • Inside IPPS are capacitors, resistors, diodes, transformers, wires, etc. • Project focuses on modification of Perkin-Elmer 222-0800 IPPS

  6. IPPS cont’d IPPS are placed in relay racks around booster gallery. The blue label indicates where in booster ring the ion pump is located.

  7. Problem • IPPS are over 30 years old • Inaccurate read-backs • Poor efficiency

  8. Solution • Investigate read-back inaccuracies • Analyze different methods for increased efficiencies • Updating out-dated components • Developing the daughter card • Filter noise

  9. Daughter Card • Contains resistors, capacitors, diodes, and gates • Squared off section in schematic • 3 main elements • Top circuit – converts current to voltage • Middle circuit – powers card • Bottom circuit – controls IPPS

  10. Daughter Card cont’d

  11. Testing Cards • Extender card for safety • Adjust R30 to 6.1V • Establish a reference level • Verify components measure accurately • Run timing tests

  12. Modifying • Obtain old power supplies • There are 55 Perkin-Elmer 222-0800 IPPS • Most components are removed as well as wires • IPPS circuitry remains similar to old

  17. Back Panel cont’d Before After

  18. Testing • Calibration of torr meter • 10/20 min run tests • 8 hour simulation test

  19. I Testing cont’d • Load resistance testing Ion pump load IPPS air

  20. Conclusions • Upgrade IPPS will lead to better control of vacuum • Setbacks • Delay in schedule • Troubleshooting • Knowledge of electrical circuits • Technical skills • Soldering • Drilling
