EVA, the 85 MeV linear lectron accelerator (ersneller) at msterdam

The 85 MeV electron linac of the Institute for Nuclear Physics Research in Amsterdam (EVA) is now fully operational. At high energies and low currents, 80% of the current of the low-emittance beam falls within a 0.3% energy-base. Maximum peak currents of up to 150 mA within a 0.8% energy-band are obtainable regularly. This performance is attained using two SLAC sections (each 3 m long), and a Frascati-type injector. The inherent properties of both are matched by the performance of the peripheral equipment which includes two klystron modulators, the cooling system, the microwave driver and interface instrumentation.
