Abstract:
In 2005 Fermilab, SNS, DESY and CERN formed a collaboration to test the DESY external antenna Radio Frequency (RF) H- ion source with an 80 kW, 2 MHz amplifier provided by the SNS. With the SNS amplifier installed the DESY source produced a 3 ms long pulse at 0.25 Hz during this site visit. The initial H- beam current was 30 mA drooping to 25 mA by the end of the pulse. This test effectively met the current requirement for the Fermilab Proton Driver, option A in table I, and comes very close to meeting the option B, CERN and BSNS requirements.
