BL4N design features

July 10, 2012 Y. Bylinski ARIEL Workshop 6

Original design was done by Rick Baartman in 2009

Main features:•Transport capacity: 200 A•Beam dump capacity: 200 A•Achromatic design •Compensation of cyclotron’s dispersion and foil move•Collimation of large angle scatters from foil (up to 1 μA)•Collimation of beam halo due to energy dispersion•Moderate aperture - 71 mm and small beam size < 15 mm•Low loss beam transport and easy access to all optics•Dedicated matching section to control beam size on target•Beam rastering on target with AC steerers at 500 Hz

Cyclotron Upgrade & Development Needs

July 10, 2012 Y. Bylinski ARIEL Workshop 11

• New extraction probe

• 15-20% more RF power (RF distribution upgrade)

• Ion source upgrade to 1mA high brightness beam

• Centre region diagnostics upgrade

• Simultaneous extraction of 4 high intensity beams

• Total extracted beam intensity to reach ~400 μA

• Intensity stabilization for multiple extracted beams

Time Line Constraints

12

• Cyclotron vault work: 2-3 shutdowns• Old front-end cleanup• New front-end installation• Beam dump construction• New extraction probe installation

• BL installation in the tunnel: 4-6 months• Electron beam line re-configuration• Electron beam delivery interruption

• Early installation for cyclotron development:• Ex probe• Beam dump

3 benders and 20 quads can be salvaged

• Rest of BL optics/PS 2100 k$• Vacuum equipment 300 k$• Diagnostics & probe 500 k$• Beam dump 500 k$• Infrastructure 500 k$• Controls 400 k$

• Total equipment budget: 4.3 M$Y. Bylinski ARIEL WorkshopJuly 10, 2012

Summary

July 10, 2012 Y. Bylinski ARIEL Workshop 15

• Basic BL4N design has been done and meets requirements

• Equipment first order count allowed budget estimate

• Detailed design has to be started ASAP

• Project may spread over 3+ years or/and seriously impact beam delivery schedule

• Early start of installations in cyclotron vault is recommended to allow time for cyclotron development

• Cyclotron upgrade activities are being coordinated with ARIEL proton beam needs
