First Results from Beam Measurements at the 3 MeV Test Stand for CERN LINAC4

The H- source and the low energy beam transport(LEBT) line will determine to a large extend the performance of Linac-4, the new machine foreseen at CERN as injector into the PS Booster.

Sumario:The H- source and the low energy beam transport(LEBT) line will determine to a large extend the performance of Linac-4, the new machine foreseen at CERN as injector into the PS Booster. For this reason a test stand is being set up, consisting of the source, the LEBT, the RFQ and the chopper line. Up to now only the source and LEBT are installed. First measurements have been performed using a Faraday Cup to measure the total source intensity, a slit and grid emittance meter for transverse emittance measurements as well as a spectrometer for energy spread measurements. Beam intensity, profile, transverse emittance and energy spread have been measured. The paper discusses measurements done on H- beams at 35 kV extraction voltage as well as proton beams at 45 keV.
