Linear resonant accelerators for industrial applications

Beams of ions with energy up to 10 MeV/A and average current up to 2 mA are required in some cases (proton accelerators as neutron sources, high-energy ion implanters, and accelerators for charged-particle activation analysis). Accelerators with alternating-phase focusing (APF) are suitable for these purposes. These accelerators have been developed and put into operation at the Moscow Physical Engineering Institute in 1987-8 (URAGAN-1 and URAGAN-2). They are designated for research work in material science and ion implantation. The work carried out shows that, at pulse currents of accelerated beams up to 10 mA in the low duty factor mode of operation, resonant linacs with alternating-phase focusing are quite competitive with RFQ (radio frequency quadrupole) ones while surpassing the latter in mass-size features. >
