Phys. Rev. ST Accel. Beams 11, 050102 (2008) [8 pages]Design and validation of an accelerator for an ultracold electron source
G. Taban1, M. P. Reijnders1, S. C. Bell2, S. B. van der Geer1, O. J. Luiten1, and E. J. D. Vredenbregt1 * Received 11 January 2008; published 7 May 2008 We describe here a specially designed accelerator structure and a pulsed power supply that are essential parts of a high brightness cold atoms-based electron source. The accelerator structure allows a magneto-optical atom trap to be operated inside of it, and also transmits subnanosecond electric field pulses. The power supply produces high voltage pulses up to 30 kV, with a rise time of up to 30 ns. The resulting electric field inside the structure is characterized with an electro-optic measurement and with an ion time-of-flight experiment. Simulations predict that 100 fC electron bunches, generated from trapped atoms inside the structure, reach an emittance of 0.04 mm mrad and a bunch length of 80 ps. ©2008 The American Physical Society
