(Bonn University) Work in digital controlled electronics for particle detectors with the first generation of ICs and design of the magnet ring of the 2.3GeV Synchrotron

1972

(Bonn University): Start of the work in RF superconductivity for particle accelerators and development pf the first LLRF control electronics

1976 to 1979

Design of the Darmstadt Superconducting Linac (S-DALINAC) together with A. Richter

1978

Discovery that cavities of “spherical shape are free of multipacting (together with D.Proch and U.Klein) based on work at Stanford and Genova

1979 Development of temperature mapping of sc. cavities at high fields

Unser erster Verstärker

1999-2000

Development of our first “balanced amplifier”

as low noise

preamplifier (1mW) and as a high power transmission amplifier (100W) for the front end of mobile communication base stations. Successful field tests in Beijing in 2004-2009

2002 return to accelerator electronics and cooperation with the COSY group at FZ Jülich.

2003

Establishment of a strategic partnership with ACCEL and start of high power amplifier and LLRF work
