In order to obtain high gain m a free electron laser a high-quality electron beam with high peak current is required . It is well-known that a microtron is able to produce a high-quality beam having low etntttance and small energy spread (1%0). Because a circular nucrotron has a linuted high-current capability a race-track design is adopted for providing(More)
Very short, high-charge bunches will be used in the next generation light sources. For example, bunch compression chicanes will be often required in order to produce very high-peak-current beams to be used in X-ray SASEFELs. However, the production and utilization of such bunches may face considerable difficulties due to radiative collective effects:(More)
Coherent synchrotron radiation (CSR) is a well known phenomenon that originates from coherent superposition of electromagnetic waves by ultrarelativistic electrons. CSR longitudinal effects during the passage of a Gaussian beam from a straight to a circular path have often been studied in a regime in which they are energy independent. Nevertheless, the(More)
At NSC KIPT the opportunity of creating the installation with subcritical reactor, driven by the electron accelerator, is examined. For obtaining the maximal stream of neutrons from neutron-producing target at minimal density of energy emission, the electron energy should lay in the range 100Ä200 MeV, and the size of target should be maximal. The other(More)
In the "TEU-FEL" project of the University of Twenty, The Netherlands, an FEL will be built which consists of a photocathode linac which will accelerate the electrons up to 6 MeV, a race-track microtron which will accelerate the electrons up to 25 MeV, a hybrid undulator, an electron bending system, and an optical cavity . The project will be carried out in(More)
During the past years, the experience gained with the TESLA Test Facility FEL resulted in several changes of its design. In addition, as the FEL is developed further to become a user facility during 2003, more details of future development of the FEL and the complete experimental hall for the users is taking shape. In this contribution, some of the aspects(More)
Nonlinear space-charge effects play an important role in emittance growth in the production of kA electron bunches with a bunch length much smaller than the bunch diameter. We propose a scheme employing the radial third-order component of an electrostatic acceleration field, to fully compensate the nonlinear space-charge effects. This results in minimal(More)
