The pulse power is 50 MW and the pulse duration is 25 mu s. The thyristor stack serves as a line swith for a pulse-forming network which provides the input power for a 20-MW klystron. The klystron provides the rf power for the infrared free-electron laser FELIX. The choice of thyristors is motivated by the required relative voltage-stability during the pulse of 0.08%. Also the pulse-to-pulse reproducibility is required to stay within 0.08%. Detailed design considerations and operational results are presented.}, year = {1996}, journal = {Nuclear Instruments & Methods in Physics Research Section a-Accelerators Spectrometers Detectors and Associated Equipment}, volume = {372}, number = {3}, pages = {446-454}, month = {Apr 1}, isbn = {0168-9002}, doi = {10.1016/0168-9002(95)01010-6}, language = {eng}, }
