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

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
![Page 14: Upgrade of SM18 Infrastructure on behalf of BE/RF-KCA section](https://reader036.vdocument.in/reader036/viewer/2022062518/56814930550346895db67124/html5/thumbnails/14.jpg)
• 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
![Page 15: Upgrade of SM18 Infrastructure on behalf of BE/RF-KCA section](https://reader036.vdocument.in/reader036/viewer/2022062518/56814930550346895db67124/html5/thumbnails/15.jpg)
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 (tbc by D. Nisbet)
• Electrical power: 3*400V 300A reserved with 400A upgrade on ERD2/M18

Status & timescale (2)
• Key dates:
• Now -> March ‘13: SM18 Cryo distribution 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 ?
