LINAC-Based Radioactive Beam Facility Proposal for A.VARIOLA (INFN ROMA1)
Explore the proposal for a LINAC-based radioactive beam facility at A.VARIOLA (INFN ROMA1) focusing on project constraints, injector layout, beam dynamics, and conclusions for a feasible accelerator with potential extensions. Short, medium, and long-term plans include inventory, material checks, machine layout, and integration strategies.

EGS proposal for a LINAC based radioactive beam facility A.VARIOLA (INFN ROMA1)
Project constraints Find a new project that is not a gamma source The project must fit the needs of the Romanian users comunity. The performance and the physics case has to represent an added value in the present research framework. The accelerator part should re use all the elements that have already been paid in phase 1 by IFIN-HH. Hardware modifications should be minimized. Robust project, no failure risks permitted
Beam Dynamics, Cathodes, Beam Loading And BBU Calculated. Laser system analysed. CONCLUSIONS We proposed a feasible LINAC based on the precedent ELI-NP injector. Tentative perfromances (to be validated in CDR) should be: 1) 10 A average current 2) Beam energy between 150 and 200 MeV 3) Normalized emittance lower than 10 mm mrad 4) Energy spread 1% 5) Bunch length < 10 ps 6) 100 Hz, 32 bunches per train, 3nC per bunch Beam dynamics and BL and BBU evaluations carried out.
At present Politically: -Demonstrate that we can make it work -Possible extensio to a three goal facility (radioactive beams, isotope production, photon angular momentum) 2 phases: 1) Install the pre injector as it is 10 Hz, 100pC, 100 MeV This should leave the space to work with only one S band section 2) Participate in defining and built the full performance machine
Short, medium, long term SHORT 1) Inventory (all the associated experts in Magurele, one week) 2) Material check (all the associated experts). In Magurele (best), plan some dedicated rooms and missions for checking (list of test to be established). Each individual at least three full weeks + time for the test definitions 3) Machine layout (2 FTE) 4) Individuate the material for STAR (compatible with the machine layout?) 5) Working point for phase 1 and participate to the initial design of the full project (phase 2) (one expert - 20%) 6) Definition of the integration plan for the machine phase 1 (needs list)
Short, medium, long term MEDIUM 1) Prepare the installation 2) Solve the integration issues 4) Finalize the design of the full project (phase 2) 5) Definition of the integration plan for the machine phase 2 (needs list) 6) Integration and commissioning Main availability of the old ELI team.
Short, medium, long term LONG 1) Finalize phase 1 2) Phase 2 TDR 3) If INFN applies for phase 2 .
MAIN MODIFICATIONS Electron gun, Cs2Te cathode Cathode Handling and transfer systems RF power lines Optical transfer lines Local shielding Dumps Main integration conformal to radioprotection requirements.
