2. What is EURISOL? Multi-user capabilities Up to 150 AMeV for 132Sn 235U
3 x 100 kW targets
(REX-ISOLDE, SPIRAL ~ few kW
HIE-ISOLDE ~ 10kW, TRIUMF ~ 50 kW)
1 x 4 MW converter (fission) target
(SPIRAL-2 ~ 200kW, SPES ~ 100 kW)
3 x post-accelerators:
150 A.MeV 132Sn for secondary fragmentation
1-5 A.MeV Coulomb barrier nuclear physics
~ 1 MeV nuclear astrophysics
~ keV ground states, solid-state physics, etc.
Cost: 1.3B€ 3
235U
LINAC: H, D, He and A/q=2 ions up to 1 A GeV

3. SOME OUTPUT FROM DESIGN STUDY
(~400 person-yrs, ~ 33M€)
Driver linac cavity IPN Orsay
Driver requires half-wave resonators and spoke resonators
2 prototypes of 3-spoke cavity at =0.15 and =0.35 fabricated and successfully tested at 4.2 K
Spoke cavity tuner 3

6. Multi Mega Watt Target Layout
DESIGN STUDY
6 x “MAFF”-type individual UC target-and-moderator units
new type of high-density UC compound tested on-line at PNPI, Gatchina

7. Beam Merging and ion source
DESIGN STUDY
Prototype ARC-ECR built at Jyvaskyla
Also: prototype RFQ coolers at ISOLDE and ORSAY
Tests of EBIS, ECR at ISOLDE, LNL, GSI and BNL

8. Design of the post-accelerator
DESIGN STUDY
SPIRAL-2 philosophy :
Smooth beam dynamics
Modular solution and simple cryostats,
Separated vacuum
Warm focussing (easier for alignment),
Possibility to insert diagnostics
Ease of tuning
Main technical requirements:
Only 2-gap cavities (high q/A acceptance)
Max. accelerating fields 7.8 MV/m
Nominal operation for A/Q between 4 and 8 8
