“…Scintillator screens have been used for nearly a century and are the simplest and most convincing device when one has to thread a beam through any accelerator. The modern versions used in accelerator instrumentation applications [134] are typically based on an activated inorganic ceramic or crystal structures, such as chromium activated alumina (Al 2 O 3 ) or Cerium doped YAG (Y 3 Al 5 O 12 ). These screens are directly inserted into the beam's path and can stand high intensities and large amounts of integrated charge.…”

Magnets are at the core of both circular and linear accelerators. The main function of a magnet is to guide the charged particle beam by virtue of the Lorentz force, given by the following expression: F = q v × B, (8.1) where q is the electrical charge of the particle, v its velocity, and B the magnetic field induction. The trajectory of a particle in the field depends hence on the particle Coordinated by F. Bordry

“…Each layout has specific limitations for the applicability at upcoming X-ray free electron lasers: Layout (a) may lead to radiation damage in the detector and is difficult to implement in an ultrahigh vacuum system. In layouts (b) [19,20], (c) [11,21], and (d) [22] the horizontal resolution is limited to the scintillator thickness because points along the primary beam axis are imaged to different locations on the detector. The field of view is limited by the depth of field of the optical system.…”

A transverse profile imager for ultrabright electron beams is presented, which overcomes resolution issues in present designs by observing the Scheimpflug imaging condition as well as the Snell-Descartes law of refraction in the scintillating crystal. Coherent optical transition radiation emitted by highly compressed electron bunches on the surface of the crystal is directed away from the camera, allowing to use the monitor for profile measurements of electron bunches suitable for X-ray free electron lasers. The optical design has been verified by ray tracing simulations, and the angular dependency of the resolution has been verified experimentally. An instrument according to the presented design principles has been used in the SwissFEL Injector Test Facility, and different scintillator materials have been tested. Measurements in conjunction with a transverse deflecting radiofrequency structure and an array of quadrupole magnets demonstrate a normalized slice emittance of 25 nm in the core of a 30 fC electron beam at a pulse length of 10 ps and a particle energy of 230 MeV.

“…Charged particle interaction with matter often results in emission of light either due to classical electromagnetic processes [1] or electron transitions in atomic processes [2]. From acceleration of ultrarelativistic particles, direct synchrotron radiation can be observed.…”
