When a radio frequency field is used to accelerate the electrons, this leads to stringent requirements on the stability of the klystron output power. We present results obtained with a 20-MW klystron which is energized by a pulse-forming network. The achieved stability of the klystron power is better than 0.1% during 20 mus.}, year = {1993}, journal = {Review of Scientific Instruments}, volume = {64}, number = {8}, pages = {2306-2311}, month = {Aug}, isbn = {0034-6748}, doi = {10.1063/1.1143926}, language = {eng}, }
