  1. 3 MeV measurement line U. Raich Linac-4 Beam Coordination Committee 20.10.2009

  2. Layout of the line Uli Raich BE/BI

  3. The BPMS Uli Raich BE/BI

  4. BPM Simulations Simulations by J. Tan Uli Raich BE/BI

  5. BPM Simulations Simulations: J. Tan Uli Raich BE/BI

  6. BPM simulations Simulations: J. Tan Uli Raich BE/BI

  7. Status of BPMs • Mechanical drawing available but not approved yet • Simulations being done to determine resolution • Position • Intensity • Phase • Consequences of debunching being studied using Giulia’s optics simulations • 3 devices + electronics foreseen for June 2010 • 3 MeV measurement line will be used as test bench for all Linac-4 BPMs Uli Raich BE/BI

  8. Transformer Uli Raich BE/BI

  9. Status of Transformer • Drawings ready for approval • Workshop is informed • The ceramics are ordered (has longest delay) and will be delivered by March 2010 • 2 Devices ready by June 2010 • Will use same electronics as transformers at source and in LEBT • 3 MeV measurement line can be used to test new (and cheaper) electronics to be used for Linac-4 • EMC tests done with pulsing Quadrupole next to the transformer Uli Raich BE/BI

  10. BSM (Feschenko Monitor) Uli Raich BE/BI

  11. Status of BSM • Preliminary drawing available • Feschenko and collaborator will come to CERN 2.11 – 6.11 to discuss details • First inspection by Didier does not show any mechanical incompatibilities • Electronics and software specifications to be formalized • Device should be ready by the end of 2010 Uli Raich BE/BI

  12. Emittance Meter / SEMGrid Uli Raich BE/BI

  13. Status of Emittance Meter / SEMGrid • Emittance meter is currently installed on 3 MeV source • Consists of slit and grid in 2 tanks • Grid to be re-used • Slit about to be re-designed for higher than source energy (up to 12 MeV)Simulations have been made • Electronics ready • LabView program ready for testing in beam • Size problems for integration into the tunnel (sticks into transport zone) Uli Raich BE/BI

  14. SEMGrid in spectrometer line • Not yet clear if in/out mechanism is needed • In/out mechanisms do exist • Integration with dump to be studied • 1 plane of 0.5mm wire distance • Electronics solution is available but a new and cheaper one may be studied • Software to be specified and written Uli Raich BE/BI

  15. Halo Monitor Uli Raich BE/BI

  16. Halo Monitor • Device developed by M. Hori • Device is ready and was tested in beam • Commissioning in 3 MeV to be done • Take-over of responsibility for this device by CERN staff Uli Raich BE/BI

  17. Instruments in the measurement line • Transformers • 2 transformers in the straight section of the line • Design done, ready for approval • Halo Monitor • finished • Emittance Meter box • hor/ver slit (on 1 movement) • hor/verSEMGrids on 2 movements • will use the SEMGrids, movement and tank from source emittance meter • new, high energy slit under design • SEMGrid • retractable hor (possibly on movement) • BPMs • preliminary design done • BSM • preliminary design received from INR Uli Raich BE/BI
