Linac Design for the LCLS Project at SLAC
نویسندگان
چکیده
The Linac Coherent Light Source (LCLS) at SLAC is being designed to produce intense, coherent 0.15-nm x-rays. These x-rays will be produced by a single pass of a 15-GeV bunched electron beam through a long undulator. Nominally, the bunches have a charge of 1 nC, normalized transverse emittances of less than 1.5π mm-mr and an rms bunch length of 20 μm. The electron beam will be produced using the last third of the SLAC 3-km linac in a manner compatible with simultaneous operation of the remainder of the linac for PEP-II. The linac design necessary to produce an electron beam with the required brightness for LCLS is discussed, and the specific linac modifications are described.

SLAC Linac RF Performance for LCLS
The Linac Coherent Light Source (LCLS) project at SLAC uses a dense 15 GeV electron beam passing through a long undulator to generate extremely bright xrays at 1.5 angstroms. The project requires electron bunches with a nominal peak current of 3.5kA and bunch lengths of 0.020mm (70fs). The bunch compression techniques used to achieve the high brightness impose challenging tolerances on the acce...
متن کاملThe Linac Coherent Light Source II (LCLS II) at SLAC
The Linac Coherent Light Source (LCLS) will be the world’s first free-electron laser at Ångström wavelengths (XFEL). It will be the first high brightness hard x-ray source with full transverse coherence. Its average brightness will exceed that of the brightest existing x-ray sources by a factor of 100 and its peak brightness will exceed them by a factor of ten billion. Its ultra-fast pulse stru...

The Linac Coherent Light Source (LCLS) project at the Stanford Linear Accelerator Center (SLAC) will produce intense, coherent 0.15 nm x-rays, with an expected peak brightness many orders of magnitude greater than existing x-ray sources and energy density as high as 4 x 10 watts/cm. These x-rays are produced by a single pass of a 15 GeV electron beam through a long undulator. The 15 GeV electro...
متن کاملFEL Simulations for the LCLS
A first Design Study Report has recently been completed [1] for the Linac Coherent Light Source (LCLS), a proposal to build an x-ray Free Electron Laser (FEL) at the Stanford Linear Accelerator Center (SLAC) as a single pass SASE (SelfAmplified Spontaneous Emission) amplifier. The proposal includes the use of a very low emittance electron beam accelerated up to 15 GeV by the last third of the S...
متن کاملThe LCLS X-ray FEL at SLAC
The design status and R&D plan of a 1.5 Å SASE-FEL at SLAC, called the Linac Coherent Light Source (LCLS), are described. The LCLS utilizes one third of the SLAC linac for the acceleration of electrons to about 15 GeV. The FEL radiation is produced in a long undulator and is directed to an experimental area for its utilization. The LCLS is designed to produce 300 fsec long radiation pulses at t...
