Proposal for FEL Experiments Driven by the National Bureau of Standards' CW Microtron.
Abstract
We propose Free Electron Laser experiments driven by the race-track microtron (RTM). The design of RTM has many exceptional properties: i) normalized transverse emittance of 10 mm mrad, comparable to a storage ring, ii) axial emittance <30 keV-degree, much superior to r.f. linacs, iii) electron energy tunable from 20 to approximately 200 MeV, iv) CW operation, v) energy stability, vi) compactness, and vii) high power-conversion efficiency. We propose accelerator up-grades to increase the peak current and to recover a significant part of the electron beam energy. It seems possible to obtain peak current of I sub p = 5-10A, for electron pulse length of leb > approx. 1.2 mm. We have made conservative estimates based on I sub p = 1.0 A in estimating the performance of the FELs to be used with the RTM. Low gain calculations indicate that the FEL can oscillate at the fundamental wavelength ranging from 0.15 to 100 micrometers. Furthermore, we will outline experiments to generate harmonic in the extreme ultraviolet radiation.
