In high-frequency pulsed magnets, such as kickers in particle accelerators, it is essential to reduce eddy currents that could be induced in the magnet core during excitation not to distort and attenuate the magnetic field pulse. A novel iron laminat

A new THz/IR/UV photon source at Jefferson Lab is the first of a new generation of light sources based on an Energy-Recovered, (superconducting) Linac (ERL). The machine has a 160 MeV electron beam and an average current of 10 mA in 75 MHz repetition

We are proposing non-destructive assay system of nuclear materials with laser Compton scattering combined with an energy-recovery linac and a laser. To construct this system for nuclear safeguards and security purpose, it is important to make the acc

The optical resonator geometry of the JAERI ERL-FEL is optimized to ensure high-power operation. The FEL power strongly depends on the performance of the optical resonator including output efficiency, round-trip loss, and interaction mode volume. The

The field of an FEL oscillator at zero detuning length of an optical cavity ( δL =0) is characteristic of self-amplified spontaneous emission (SASE) FEL. For both cases, the field is composed of the precedent incoherent and subsequent coherent state

An energy-recovery linac (ERL) for a high-power free-electron laser (FEL) has been designed and constructed at Japan Atomic Energy Research Institute (JAERI). The construction of the ERL was completed and first energy-recovery operation and first FEL

The sustained saturation in an free-electron laser (FEL) oscillator at perfect synchronism of an optical cavity (dL ¼ 0) was experimentally verified despite the well-known lethargy effect (Phys. Rev. Lett. 86 (2001) 5707). Formation of an FEL field
