Abstract

The superconducting CW- LINAC (1.3 GHz) of the radiation source ELBE is in permanent operation since May 2001/1/. In 2011 an upgrade program of ELBE is in progress to support additional applications. One part of the program is to double the RF-power per cavity to at least 16 kW. Since we started ELBE in May 2001 substantial progress was made in all fields contributing accelerator science. As far as RF-amplifier technology is concerned IOT-based and Solid State Amplifiers compete with klystrons. To prepare for the power upgrade of ELBE we developed a couple of activities, like:

Test of the ELBE RF-couplers and waveguide windows
Test of an available 30 kW IOT amplifier with beam
Test of a 10 kW solid state amplifier (SSPA) with beam
Test of two 10 kW SSPA’ s with beam
Redesign of the Low level RF controller
Redesign of the technical water cooling.
