  1. Canadian Light SourceCommissioning Progress CLS Annual Users Meeting – 2003-11-15

  2. Facility Layout

  3. Booster Commissioning • Blue: Dipole Field • Yellow: PCT average current – 8 mA • Green: FCTpeak current – 40 mA injected, 20 mA extracted

  4. CLS Storage Ring • 2.9 GeV DBA lattice with 12-fold period • 170.88 m circumference • Nominal Tune: x = 10.22 y = 3.26 • Eloss per turn: > 0.876 MeV • Bend magnet radiation: c = 1.6 Å Ec = 7.6 keV • x (natural damped) = 18.1 nm•rad • Damping times: • x = 2.4 ms, y = 3.8 ms, E = 2.7 ms • ~10 mm bunch length

  12. Storage Ring

  13. Storage Ring Straight

  14. Commissioning Plan • 4-week Runs: 2 installation + 2 run • Started 2003 September • Initial sequence: • First turn • Stored beam • Stacked beam • Vacuum conditioning • Radiation survey for licensing • Goal: • 100 mA • > 6 hour lifetime • Good reliability and stability

  15. Storage Ring Commissioning – Run 1 • Yellow: Storage Ring current at injection septum Measured on 2003-09-26

  16. Storage Ring Commissioning – Run 2 • Green: Storage ring current Measured 2003-10-25

  17. Storage Ring Commissioning – Run 3 • Green: Booster beam • Pink: SR1 beam loss measured by CBLM Measured 2003-11-14

  18. Plan for 2004 • Q1: • SGM/PGM front-ends, POE and IDs • Optical chicanes for IR lines • Start of day-time operation • Q2: • SM and PX front-ends, POEs and IDs • XAFS front-end and POE • Q3: • XAFS wiggler • Tentative start of 24-hour operation • Q4: • Increase current to 200 mA and lifetime to ~10 h

  19. Future Projects • Modifications for top-up operation • Fast transverse feedback • Linac modifications/upgrade • Come to Sunday session to discuss other long range possibilities
