KFA71

18/03/2015W. Weterings

Ejection kicker magnet KFA71 Together with magnet KFA79, this device kicks the beam in the aperture of SMH16 for extraction.Installed in 1973.

• Configuration:• 1 tank with 9 magnet modules;• The magnets are of cellular,

closed aperture, C-ferrite loaded transmission line type, 15Ω impedance.

• 1 spare tank with 9 modules exist. (not operational for the moment)

• Current status:• All 3D CATIA models of magnet modules made and 2D drawings ready, but not checked.• 2 modules have been repaired;• Modules will be individually tested before assembly in the 9 modules spare tank.

KFA79

• Configuration:• 1 tank with 3 magnet modules;• The magnets are of cellular,

closed aperture, C-ferrite loaded transmission line type, 15Ω impedance.

• 1 spare tank with 1 module exists.

• Current status:• All 3D CATIA models of magnet modules made, 2D drawings ready (but not checked).• At least 2 modules to be built;• No supplier for ‘shiny’ laminated AlMg3 plates known, possibility of electro polishing to be

investigated.

KFA45

18/03/2015W. Weterings

Kicker magnet KFA45.Used to inject protons into the PS.Installed in 1979.

• Configuration:• 1 tank with 4 magnet modules;• The magnets are of cellular, closed aperture,

C-ferrite loaded transmission line type,characteristic impedance of 26.3Ω.

• Originally designed to inject 800MeV proton.• 1 spare module exists.

• Current status:• All 3D CATIA models of magnet modules

made, 2D drawings ready (but not checked). Drawings of the tank still to be made;

• At 2 GeV at the limit of saturation, operation with only 3 modules will be impossible.• 1 tank and at least 3 modules to be built, redesign for non-saturation to be considered.

7SPS Consolidation Review

• Configuration:• 3 tanks with 2 magnet modules;• Different thickness of lamination

between the magnets.• No spare exist.

• Current status - Nothing has been done…….• Spare magnet with thinner lamination would be preferred, due to lower eddy currents;• Current magnets suffers from outgassing issues caused by the lamination oxidation;

Improvement by different lamination insulation or bake-out to be studied.
