  1. PS East Area operation… …or the PS travel agency

  2. Menu (TVA 19.6% included) • Where is East ? • Our responsibility • Destinations • How to reach the targets? • Triple ppm and OB-names • External conditions • Beam lines setting-up • Adjust the beam • T7 secondary/irradiations • OP display • Acknowledgments Marc Delrieux

  3. Where is what? EAST HALL Marc Delrieux

  4. NORTH AREA: target F61N.MTV02 Our responsibility T8 AREA: Target ZT8.MTV02 T7 AREA: ZT7.MTV01 (sec.) Target ZT7.MTV03 IRRAD T7 AREA: F61S.BHZ02 (irrad.) TO T7 SEC Marc Delrieux

  5. Destinations • Only to North • N • Only to South • T7 • T8 • Shared between North and South • NT7 (secondary/irradiation) • NT8 (not used for DIRAC) Marc Delrieux

  6. How to reach the targets?? NO FIELD USE F61.SMH01 SPLITTER!!! FIELD NO FIELD Marc Delrieux

  7. How to reach the targets?? 100%  NORTH N Marc Delrieux

  8. How to reach the targets?? 100%  North N Beam is not deflected and goes to the North branch Marc Delrieux

  9. How to reach the targets?? 100%  SOUTH T7 secondary T8 Marc Delrieux

  10. How to reach the targets?? 100%  South T7 secondary, T8 Whole beam is deflected to the South branch Marc Delrieux

  11. How to reach the targets?? T7 secondary shared with T9, T10 and T11 (NT7) Marc Delrieux

  12. NT7 secondary Fair enough: 50-50! How to reach the targets?? 50%  South 50%  North Marc Delrieux

  13. How to reach the targets?? T7 irradiation shared with T9, T10 and T1 (NT7) T8 shared with T9, T10 and T11 (NT8) (not used) Marc Delrieux

  14. How to reach the targets?? 35%  North 65%  South NT7 (irradiation) Center part goes to T7 Lower and upper parts are recombined and sent to North Marc Delrieux

  15. How to reach the targets?? N T7, T8 NT7 secondary NT7 irradiations Various settings are needed!!! Marc Delrieux

  16. OB-NAMES XXX.DHZ02YY Suffix triple PPM Equipment name Beam Line prefix Marc Delrieux

  17. Triple PPM ppm: 1 value per user Triple ppm: 3 possible values per user: depends also on DESTINATION!!! One table for each user EASTC F61.DHZ01NS 10Amp F61.DHZ01S 1Amp F61.DHZ01M 0Amp NT7 or NT8 POWER SUPPLY T7 or T8 N EASTC EASTB One table for each user EASTB F61.DHZ01NS 8Amp F61.DHZ01S 2Amp F61.DHZ01M 0Amp NT7 or NT8 POWER SUPPLY T7 or T8 N Marc Delrieux

  18. OB-NAMES: triple PPM XXX.DHZ02YY Marc Delrieux

  19. Triple PPM (suffixes w.r.t destination) Marc Delrieux

  20. External conditions All beam requests and inhibits are treated as external conditions • REQUESTS • R_P.EASTA • R_P.EASTB • R_P.EASTC • R_P.EAST_N • R_P.EAST_T8 • R_P.EAST_T7 • INHIBITS • I_P.EAST_N • I_P.EAST_T8 • I_P.EAST_T7 Software Requests if destination is PS • Physicists requests: • Hardware in the physicists barracks • Can be overwritten by software Control room inhibits (hardware) Marc Delrieux

  21. If destination is T8 R_P.EAST_T8 I_P.EAST_T8 Beam executes & External conditions If destination is N R_P.EAST_N I_P.EAST_N & Beam executes If destination is NT7 If destination is T7 R_P.EAST_N I_P.EAST_N & Beam executes BUT destination CALCULATED!!!! R_P.EAST_T7 I_P.EAST_T7 & >= Beam executes R_P.EAST_T7 I_P.EAST_T7 & XXX = Hardware request that can be overwritten XXX = Hardware inhibit form CCC Marc Delrieux

  22. External conditions (NT7 calculated) Marc Delrieux

  23. Beam lines setting-up Look on the EAST AREA web page: Marc Delrieux

  24. Beam lines setting-up Which elements do the heavy job? The bendings. • In the common line (F61): • BHZ01 and BHZ02 (Beam to dump elements) • The north area (F61N): • BVT01 • The south area (F61S): • BHZ01 • BHZ02 (limited triple PPM) • The T8 area (DIRAC): • BHZ01 • BHZ02 (both triple ppm) • The T7 area: • BHZ01 (triple ppm) The small corrections are done with triple PPM elements Marc Delrieux

  25. Adjust the beam F61.MTV01 (first screen in the East Area) • Steering • PE.SMH61, PESMH57 (check BLMs 57, 61, 63) • Horizontal size • QFO01 Marc Delrieux

  26. Adjust the beam Splitter: screens MTV02 and MTV03 • Horizontal ejection error • DHZ.01 • Vertical size on splitter • QDE02 • Vertical position on splitter • DVT01, DVT02 • Focalization on splitter • QFO03, QDE04 Marc Delrieux

  27. Adjust the beam F61N.MTV02 (target) • Horizontal size • QDE01 • Vertical size • QFO2 • Horizontal position • DHZ01 =>compensation of sweep due to energy spread in beam (controlled with GSDHZ01) • Vertical position • DVT01 ZT7.MTV01 (target) • Horizontal size • QFO01 • Vertical size • QDE02 • Vertical position • DVT01 • Horizontal position and sweep • DHZ01 (GFA) Marc Delrieux

  28. T7 Secondary/Irradiations Why don’t we EVER use T7 for irradiation? Sweep NON HOMOGENEOUS T7 Splitter knives Sweep HOMOGENEOUS NT7 Marc Delrieux

  29. T7 irradiations: sweeping Sweeping is done with F61S.GSDHZ01 Marc Delrieux

  30. T7 secondary F61S.GSDHZ01 Compensation of natural momentum spread in order to maintain the beam on the (tiny) target Marc Delrieux

  31. OP display (EASTC) Marc Delrieux

  32. OP display (EASTB) Marc Delrieux

  33. Acknowledgments • Ronaldus who made the first course • Frank and Denis who helped me to prepare • Bernard who replaces me on shift • Rende who explained me everything • Lambil/Cauvin for the drawings coming from “Les Tuniques Bleues” • Rende who will now answer your questions :o) Marc Delrieux
