3 Y. Bylinski ARIEL Workshop3 ARIEL Facility Layout July 10, 2012

4 BL4N Tunnel Cross-section July 10, 2012Y. Bylinski ARIEL Workshop4 Protons Electrons

5 Beam Parameters Requirements July 10, 2012Y. Bylinski ARIEL Workshop5 Energy – 470-500 MeV Intensity – 1-100 μA Beam losses < 1 nA/m. Beam size at the target 2-10 mm (FWHM) Uniform beam density distribution on the target Beam spot position instability < 1mm Intensity instability <1%

6 BL4N design features July 10, 2012Y. Bylinski ARIEL Workshop6 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

11 Cyclotron Upgrade & Development Needs July 10, 2012Y. Bylinski ARIEL Workshop11 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

12 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 Y.
