“…The number of resonators would be nearly halved; the Linac overall length and cost could be reduced significantly. 2-gap cavities for a similar application have been first developed at Argonne [23].…”

The Project SPES (study and production of exotic nuclei) aims at the full design of a facility based on a 100 MeV, 1-30 mA CW proton Linac used for production of fission fragments from a uranium like-target by means of a neutron converter. Neutron rich ion species are extracted, selected, further ionized at high charge state, isotopically purified and then accelerated through a superconducting Linac at energies up to 20 MeV/A. SPES represents INFN's effort in view of the construction of the European next generation ISOL-type facility, which is expected to be operative by 2010. A conceptual design report of such a European facility is being prepared with the support of the European Commission. R&D activities, covering the most critical parts of the facility, have been partially started in the last two years, triggered by the French-Italian feasibility study of an accelerator driven system for waste transmutation.

“…With this change some $20 M of annual operational costs will be saved. Since we did not have any experience with spoke cavities, and ANL (Argonne National Lab) has been developing them for many years [2][3][4][5][6][7][8], ANL kindly loaned us one of their cavities in November 2000. Since then, we have tried the following: (1) familiarize ourselves with the cavity, (2) benchmark computer codes for designing spoke cavities for LANL and (3) estimate achievable performance with our present technologies at LANL.…”

Within the framework of the Advanced Accelerator Applications (AAA) project we are interested in building and testing low-β spoke resonators (cavities). To familiarize us with the specifics of these structures Argonne National Laboratory (ANL) kindly loaned us one of their spoke cavities for evaluation. This is a β=0.291 2-gap resonator at 340 MHz. We benchmarked our computer codes by comparing room temperature measurements of frequency, tuning sensitivity, tuning forces, etc. with our 3D simulation results. The cavity was tested at both 4 K and 2 K. The results showed maximum accelerating gradients of 12.5 MV/m (4 K) and 12.3 MV/m (2 K), which correspond to a peak electric field of 40 MV/m and a peak magnetic field of 1063 Oe. Q 0 values at 5 MV/m also exceeded by more than a factor 2 of present AAA specification. These results encouraged us toward development of spoke cavities for the low energy section (6.7 MeV to 109 MeV) of ADTF (Accelerator-Driven Test Facility) of AAA project.
