Laser-wire

Line: 10 to 10
 The performance of linear collider depends strongly on the control of the transverse particle beam size along the complete machine, for example to verify beam optics and to measure the transverse beam emittance. Some of the expected beam sizes are in the range between 500 nm and 10 Ám, where conventional wire scanners are at the limit of their resolution. To provide a non-invasive measurement we suggest to use a laser beam to probe the electron beam. The central idea is to use Compton scattering between electrons in the bunch and photons in the laser beam

Installed laser wire projects

A laser wire is a system which installed in ATF extraction line and at PETRA2. We are also developing fast laser scanners. There is a program of lens characterisation and performance study here.
