Emittance Measurement of a High Brightness Pseudospark Produced Electron Beam
We report the emittance measurement of a electron beam produced in a pseudospark discharge device driven by a pulse line accelerator. A ten gap pseudospark device was operated at 200 kV, with anitrogen gas fill presure of 15 Pa. Small diameter (~1 mm) electron beam with current about 2 kA has been generated. The rms emittance of the beam is measured to be ε rms ≈ 48 mm·mrad about 5 cm downstream of the anode plane. The normalized emittance is then found to be ε n≈ 47 mm·mrad.
