Proposed Conventional Sextupole for Installation at A0

Introduction (Dean Still)Reasons for installation- Reduce I in S6 feeddown sextupole circuit at injection and possibly up the ramp.

Magnetic Parameters – ( Vladimir Shiltsev, Dave Harding, Yuri Alexahin)Does the magnet need to ramp?Ramp tests.Possibly of building laminated version

Mechanical – (Mike Mcgee, Bill Robotham)Will it fit into the A0 space?Requires stand modification.Requires entire magnet rotated +/- 30 degrees.

Electrical/Power Supply – (Wolff)Need to know

Installation – (Jim Volk)MechanicalCable pullsControlsWater Manifold

Proposed Conventional Sextupole for Installation at A09/12/03 Meeting

Magnetic Parameters – (Dave Harding)Look at measurements preformed.

Mechanical – (Mike Mcgee, Bill Robotham)Look at proposed mech. changes from Bill.(Dean)

Electrical/Power Supply – (Wolff)Update to power supply needs.Need to know ripple requirements.

Accumulator Skew Sextuple

Length: 30 in.Bore: 4 in.Coil: 21 turnsHeight: 15 ¾ in.

If turned ,~10 3/4 in. from beam center to edge of steel.

Will need to cut feet off and rotate.
