3. Main characteristics of Cyclone 70 Extracted beams ~1.23 T.m Beam exit 2 exits 2 x 3 ports (*) RF 145 Tons On 4 pillars Cyclotron weight radius Vacuum system 30 (xp) ot 58 (p) MHz Mean 65 kV 22 kW (2 cavities) 56 kW (beam load) Frequency Dee s voltage Power - cavity Power full beam 1240 (pole) Cryo pumps 1910 mm (overall) Clean vacuum cyclotron Clean vacuum ion source Turbo pumps 60 kW < 250 kW Stand-by Full beam /2 Beam lines (%) Load included in (%) Electrical load ~25 kW (two beam lines) Cooling load < 200 kW Full beam, water chiller NB: loads of details at cyclotrons & ECPM conferences as from 2007 - 3 - Protect, Enhance and Save Lives

4. Current status multi-particle 70 MeV / 750 A proton - World record established 10/2010 - 4 - Protect, Enhance and Save Lives

5. Current status of the proton only Zevacor project being shipped soon, CDMN under mapping this summer 20 months from order to shipment of 1st Unit - 5 - Protect, Enhance and Save Lives

6. Overview Overview: : from from source to extraction source to extraction

7. Sources H-/D- => multicusp ion source from D-pace Capacity 10mA H-, superbright emittance 30 kV platform Easy maintenance (one back plate with 4 filaments) Differential pumping system for high vaccum level q/M=0.5 => supernanogan from Pantechnik - 7 - Protect, Enhance and Save Lives

8. Injection Line overview Multi-particle machine Quad triplet 90 bend solenoid solenoid Buncher solenoid good match : particle accepted for Protect, Enhance and Save Lives more than 50 turns) - 8 -

9. Injection line overview Proton only: simplified design H- proton source and injection (same as high current Cyclone 30 HC) - 9 - Protect, Enhance and Save Lives

10. Injection line overview Proton only, cont d - 10 - Protect, Enhance and Save Lives

11. Magnet - 11 - Protect, Enhance and Save Lives

12. Magnet Multi-particle machine - 12 - Protect, Enhance and Save Lives

13. Magnet : compromise for all particle Computation, CA Design and engineering - 13 - Protect, Enhance and Save Lives

14. Magnet Main differences between proton only and multi-particle Yokes/flux returns in 1 piece No more compensation coil No more pole extension (He++ focalisation) Optimisation of pole thickness and profile Gap increasing (30mm ->40mm) Why? Assembly optimised Better vacuum level Reduce power consumption (main coil + harmonic coils) Improve vacuum pumping - 14 - Protect, Enhance and Save Lives

15. RF system Cyclone 70Xp - ~30 MHz in H2 for protons, H4 for M/Q=2 Different stem configurations have been tested in order to find the best compromise between mechanical/RF/beam parameters. Large number of turns for protons; possible higher losses in acceleration 120 V dee (kV), Energy gain(keV) 100 V dee (kV peak) Arronax case (H2) 80 60 Energy gain/gap (keV) V Dee centre: 65kV #of turns: 625 P Diss.: 20kW (measured) 40 beam lost/ 100mm radius increase (arbitrary scale) 20 0 0 500 Radius 1000 - 15 - Protect, Enhance and Save Lives

16. RF system Cyclone 70Xp - H2 for protons, H4 for M/Q=2 Harmonic 2 for proton acceleration 30Mhz (compromize with other particles) Inductive coupling (in the pit) - 16 - Protect, Enhance and Save Lives

17. RF system proton only Protons on 4th harmonic RF H2->H4 allow to gain ~4% of transmission Straight pillar 110mm (better rigidity) Vcentre: 50kV P diss: 32.7kW #of turns: 625=>321 90 V dee (kV), Energy gain(keV) 80 V Dee (kV peak) 70 60 Energy gain/gap 50 40 Beam losses 30 20 10 0 0 500 Radius 1000 - 17 - Protect, Enhance and Save Lives

18. RF system proton only, while were busy with it Direct FPA coupling to Dee: more stable system Cyclone 30HC amplifier Coupling in median plane no asymmetry between cavities low amplifier and coupler dissipation at 80 kW total RF (100 kW available) only one cavity tuning at the opposite side of the coupler. - 18 - Protect, Enhance and Save Lives

19. Extraction systems Electrostatic deflector Electrostatic deflector is coupled to pole extensions for optics correction We burned some of these during commissioning despite the cooled pre-septum (less turn separation than IsoDAR, so we cannot remove halo) - 19 - Protect, Enhance and Save Lives

20. Extraction systems Dual stripping shaft and permanent radial probe - 20 - Protect, Enhance and Save Lives
