The projected electrical beam deflection system for the generation of a 40 ns proton beam pulse in the CERN 600 MeV synchrocyclotron is described. A test model of the most critical part of this system, the triggered spark gap, has been constructed and tested carefully. The necessary operation conditions of this gap (electrode distance, gas flow andngas pressure) are described to obtain a deflection pulse of 45 kV, 10 ns rise time and ± 5 ns jitter.
