The second bunch compressor chicane in the main beam line of the multi TeV linear collider CLIC is foreseen to compress the electron bunches from 250 μm to 30 μm. It is specified that the emittance growth in this chicane, which is mainly due to incoherent and coherent synchrotron radiation, should not exceed 30 nm·rad in the horizontal plane and 1 nm·rad in the vertical plane. To achieve these values the chicane layout and the optics functions have been optimized and the influence of shielding due to the vacuum chamber including resistive wall wake fields has been studied. A chicane layout and the corresponding electron beam parameters are presented, which allow to preserve the emittance within the specifications.

The Linac Coherent Light Source (LCLS) is a SASE x-ray Free-Electron Laser (FEL) based on the final kilometer of the Stanford Linear Accelerator. One of the most critical diagnostic devices is the bunch length monitor (BLM). We are planning to install BLM right after each compressor utilizing coherent radiation from the last bending magnet. We will calculate the signal strength, and simulate the signal propagation using well-accepted simulation tools in synchrotron radiation community in general, and THz radiation in particular. We will also discuss issues of optics layout, and detectors.
