Abstract
Development of powerful Ka-band FEM-amplifiers with broad frequency tuning
Highlights
During the several preceding years, an oscillator scheme of a free electron maser (FEM) has been realized in the joint experiments between JINR (Dubna) and IAP RAS (Nizhny Novgorod) [1]
The project was aimed at accelerating applications, and the FEM operates in a frequency range of 30 GHz and generates 20 MW / 200 ns pulses with a spectrum width of 6–7 MHz, which is close to the theoretical limit
The high output power and stability of a narrow-band operation regime allowed this JINRIAP FEM to be used in a number of actual demand applications, including testing the components of highgradient accelerators of the generation [2]
