## 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)
- 	Mechanical
- 	Cable pulls
- 	Controls
- 	Water Manifold

## Proposed Conventional Sextupole for Installation at A09/12/03 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.
- Installation – (Jim Volk)
- 	Mechanical
- 	Cable pulls
- 	Controls
- 	Water Manifold

## Proposed Location – A0

- F49

## Location to Install

- Install upstream of A0 abort block

- Floor is ground up

- F49

## Other Sextupole Options

- TESLA

- MI ISA

- MR SEXTUPOLE

## Accumulator Skew Sextuple

- Length:  30 in.
- Bore:	4 in.
- Coil:	21 turns
- Height:	15 3⁄4 in.
- If turned ,
- ~10 3/4 in. from beam center to edge of steel.
- Will need to cut feet off and rotate.
