| MOPPH012 | The Conceptual Design of the 4GLS XUV-FEL | 63 |
|
||
| The Conceptual Design Report for the 4th Generation Light Source (4GLS) at Daresbury Laboratory in the UK was published in Spring 2006. A key component of the proposal is an XUV-FEL amplifier directly seeded by a High Harmonic source and operating in the photon energy range 8-100eV. Numerical modelling shows the FEL may generate ~50fs (FWHM) pulses of variably-polarised, temporally-coherent radiation with peak powers in the range 2-8 GW. | ||

| Using High Harmonics (HH) as a seed for free electron lasers is currently under consideration in a number of proposed facilities. An HH seed source is independent of machine dynamics, and allows for extensive manipulation of the seed pulse using well-established techniques of ultrafast laser physics. These allow for rapid tuning, and may enable the extension of chirped pulse amplification and even pulse shaping for coherent control to short wavelengths. In addition, there are advantages in terms of noise and synchronization. There are a number of issues involved in the implementation of HH seeding: energy, tunability, coherence, temporal structure, etc. We discuss these issues and their application in the 4GLS XUV-FEL | ||

4GLS is a facility proposed for the Daresbury Laboratory in the UK* which will offer users a suite of high brightness synchronised sources from THz frequencies into the XUV. In the current design, photon energies from 8-100eV will be generated in a variable polarisation FEL amplifier directly seeded by a High Harmonic Gain system. The reasoning behind this choice will be discussed and characterisation of the sources based on the present design presented.
