| Popis: |
Beam operation of a novel E×B chopper system has started in the low-energy beam transport (LEBT) section of the accelerator-driven neutron source FRANZ. The chopper is designed for low-energy high-perveance beams and high repetition rates, and will finally operate with 120 keV protons. It combines a static magnetic deflection field with a pulsed electric compensation field in a Wien filter-type E×B configuration. The chopper was designed, manufactured and successfully commissioned at the required repetition rate of 257 kHz using a 14 keV helium beam with up to 3.5 mA of beam current. Beam pulses with rise times of (120±10) ns, flat-top lengths of (85±10) ns to (120±10) ns and full width at half maximum (FWHM) between (295±10) ns and (370±10) ns were experimentally achieved. |
