FEL 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 کاملPhotoinjector design for the LCLs
The design of the Linac Coherent Light Source assumes that a low-emittance, 1 nC, 10 ps beam will be available for injection into the 15GeV linac. The proposed rf photocathode injector that will meet this requirement is based on a 1.6cell S-band rf gun equipped with an emittance-compensating solenoid. The booster accelerator with a gradient of 25MV/m is positioned at the beam waist coinciding w...
متن کاملDynamic Collimation for Linear Colliders
Experience with the SLC has indicated that backgrounds caused by the tails of the transverse beam distribution will be a serious problem for a next generation linear collider. Mechanical scrapers may not provide the best solution, because they may be damaged by the tiny, intense beams, and dso because they may induce wakeiIeld kicks large enough to cause emittance dilution. In this paper, we pr...
متن کاملSpontaneous Radiation Background Calculation for Lcls∗
The intensity of undulator radiation, not amplified by the FEL interaction, can be larger than the maximum FEL signal in the case of an X-ray FEL. In the commissioning of a SASE FEL it is essential to extract an amplified signal early to diagnose eventual misalignment of undulator modules or errors in the undulator field strength. We developed a numerical code to calculate the radiation pattern...
متن کاملBeam Collimation during Lumbar Spine Radiography: A Retrospective Study
Introduction: Collimating the primary beam to the area of diagnostic interest (ADI) has been strongly recommended as an effective method to reduce patient’s radiation dose and to improve image quality during radiology practice. Lack or inadequate collimation results in excessive radiation dose to patients and deterioration image quality.Objective: To assess the quality of beam collimation dur...
