A new pre-injector for the MAX-Laboratory is under design and construction.
A thermionic RF gun, designed to operate at medium currents with low back
bombardment power, is under construction. The gun will, via a magnetic comp
ressor and energy filter, feed a recirculated linac consisting of two SLED-
equipped structures giving 125 MeV each. The first will be delivered in 199
9. The system is aimed as a pre-injector for the existing storage rings at
MAX-Lab, but will also open up possibilities for a SASE FEL in the UV reach
ing above 100 MW below 100 nm. (C) 2000 Elsevier Science B.V. All rights re
