  1. Upgrade of SM18 Infrastructureon behalf of BE/RF-KCA section

  2. Contents • Cryogenics • Vertical test stand V3 • Horizontal bunker M7 • Klystron • Wave guides • Status and timescale

  3. Cryogenics • Vertical test stand V3 Yesterday

  4. Warm up bath for pumping Old separated lines

  5. Tomorrow Common insulation vacuum Integrated pumping New cryostat with active screening and earth magnetic field compensation Welded connection

  6. Internal tubing with exchanger and valves Surrounded by superinsulation

  7. 4 Cryo service modules in workshop oct.12 Internal section of the distribution line. Cold He return make screening of the liquid He delivery

  8. V3,4,5,6 Cryo service modules welded in SM18

  9. Cryogenics • Horizontal bunker M7 CCDTL Dismantling old lines

  10. Klystron • Operating frequency f0 : 704.4 MHz • Peak output power at saturation and load VSWR ≤ 1.05 ≥ 1.5 MW • Average output power at saturation and load VSWR ≤ 1.05 ≥ 150 kW • Operating point, below klystron saturation ≤ -1.5 dB • Saturated gain ≥ 40dB • Drive power max 200 Watts • Peak cathode voltage (Ub) at rated output power ≤ 115 kV • Peak cathode current (Ib) at rated output power ≤ 25 A • HV pulse duration 2 ms • HV rise & fall time (each) 80 - 150 μs • RF pulse duration (plateau) 1.7 ms 300 μs(LLRF)+1400 μs(Beam) • Repetition rate 50 Hz

  11. Wave Guides Integration in M7 well advanced (BE/RF, EN/MME (drawing office)) Power distribution Cryomodule (incl. slope) New standard 2 kelvin service module Still to be done: Detailed integration of cryomodule repair scenarios (i.e. how to lift the top cover of the CM?) Cabling (RF and Cryo) SPL valve box to build

  12. Adaptation of Wave guides to module change of tilt Tests at 0% and 2 (4?) % slope: Will require WG distribution modifications (1-2 hours) CM lifting device to be defined

  13. Status & timescale (1) Procurement of equipment: Klystron(1x): 1.5 MWp ordered, delivery end Summer ‘13 Circulator(1x): ordered, delivery Summer ’14 (on purpose, for budget reasons) RF loads (3x): 1.5MWp ordered, delivery January ’13 Waveguides: special pieces (magic tees, bends, bellows) ordered at Mega Industries (USA) (≈50 k$) all straight parts from Spain (≈50 kEuros) Modulator: delivery expected by Fall’13 (tbcby D. Nisbet) Electrical power: 3*400V 300A reserved with 400A upgrade on ERD2/M18

  14. Status & timescale (2) Key dates: Now -> March ‘13: SM18 Cryodistribution replacement March -> End Summer ‘13: CCDTL tests (Linac 4) September -> December ’13: SPL HPRF system installation Providing the L4 RF tests are moved in Bld150 (3 MeV test stand)? (tbc by F. Gehrig) Controls: HPRF controls: re-use the PLC system developed and installed for L4 test stand Cryomodule: RF controls expected to be ready by 2014 ( L. Arnaudon ) Cryo controls to be defined ( TE/CRG ) Attention LS1 ! Low level ?
