Abstract

A source of ultra-fast synchrotron radiation pulses based on a recirculating superconducting linac is proposed at LBNL. A flat beam will be produced in the low energy phase. High-brightness photocathode rf gun will produce electron beams in a solenoidal magnetic field. The electron beam will be transformed into flat beam with a large x/y emittance ratio by a skew-quadrupole-sequence adaptor. A theoretical model is shown and simulations have been done with PARMELA. Space charge effect and possible solenoid setup are reported
