Computer simulation of the electrical circuit of the wideband power amplifier for the transverse damping system of LHC

To accelerate the development of the wideband power amplifier for the LHC transverse damping system a computer simulation was made using Microsim PSpice software. A new technique of creating vacuum tubes models was developed, on the basis of which a model for the Siemens RS2048-CJ tetrode was made. Results of the amplifier circuit simulation show very good agreement with measurement results on the prototype hardware, both in time domain analysis as well as in frequency domain analysis.
