We describe the design of a planar undulator with unusually strong tapering, for the inverse FEL experiment (on the IFEL experiment at the UCLA Neptune Lab. Presented at the 2001 Particle Accelerator Conference, June 18–22, 2001, Chicago, Illinois)

New non-collinear schemes are suggested for transverse velocity modulation of electron beams and for the generation of coherent spontaneous radiation by these transversely modulated beams. It is shown that due to the non-collinearity some orders of m

A new kind of e-beam bunching enabling the production of coherent spontaneous emission (CSE) is proposed and considered. It is shown that an e-beam in passing through an undulator will induce CSE along with incoherent spontaneous radiation on the sam

A high-power,frequency-tunable electrostatic free-electron maser, being developed at the FOM Institute for Plasma Physics "Rijnhuizen," shows lasing at various frequencies. An output power of 730 kW at 206 GHz is generated by a 7.2-A, 1.77-MeV electr

We report measurements of very large output intensities corresponding to a gain larger than 10{sup 5} for a single pass free-electron laser operating in the self-amplified spontaneous emission (SASE) mode at 12 {mu}m . We also report the observation

Improvements of pulsed wire method are made with the purpose to make it applicable for accurate field measurements in long undulators. It is shown that the focusing strength of an undulator can be measured with rather high accuracy for both transvers

A description of a new 2 m undulator is presented which was specially designed and manufactured for a SASE mode FEL experiment. It is a one section two plane focusing permanent magnet construction. The uniform period length is 2.06 cm, total number o

A possible influence on the FEL dynamics of a locally induced phase jump between the FEL radiation and electron beam is considered. A numerical study has been made for the SASE mode FEL supposing that the phase jumps are introduced at different depth

A novel multicomponent undulator scheme is proposed which has new elements inserted between the undulator sections. Such elements induce some delay of a radiation wave packet with respect to the radiating electron. It is shown particularly that for t
