Beam Profile Measurement at 30 GeV Using Optical Transition Radiation
We present results of measurements of spot size and angular divergence of a 30 GeV electron beam though use of optical transition radiation (OTR). The OTR near field pattern and far field distribution are measured as a function of beam spot size and divergence at wavelengths of 441, 532, and 800 nm, for both the single and double foil configurations. Electron beam spot sizes of 50μm rms have be...
متن کاملOtr Polarization Effects in Beam-profile Monitors at the Fermilab A0 Photoinjector*
Optical transition radiation (OTR) imaging for transverse beam-size characterization is a well-established technique at many accelerators including the Fermilab A0 photoinjector (A0PI) facility. With low beam energies of 14-15 MeV and emittances of 3 mm mrad, one observes beam sizes of 0.8 to 1.5 mm (sigma). However, the use of 50-μm wide slits to sample the beam’s transverse phase spaces signi...
متن کاملBeam Transverse Profile Monitors for Ifmif-eveda
In the framework of the IFMIF-EVEDA project, a high deuteron beam intensity (125 mA 9 MeV) prototype accelerator will be built and tested at Rokkasho (Japan). CEA-Saclay group and CIEMAT-Madrid (Spain) are responsible for the beam instrumentation from the ion source to the beam dump. One of the most challenging diagnostic is the Beam Transverse Profile Monitor. Two kinds of monitor are investig...
متن کاملBeam Profile Monitors in the Nlcta *
The transverse current profile in the Next Linear Collider Test Accelerator (NLCTA) electron beam can be monitored at several locations along the beam line by means of profile monitors. These consist of insertable phosphor screens, light collection and transport systems, CID cameras, a frame-grabber, and PC and VAX based image analysis software. In addition to their usefulness in tuning and ste...
متن کاملOptical metasurfaces for polarization-controlled beam shaping.
We have developed multifunctional optical beam shapers based on plasmonic metasurfaces. The metasurfaces are composed of subwavelength-spaced polarization- and wavelength-selective optical nanoantennas that allow encoding several beam shapers on a single element. We demonstrate numerically and experimentally beam shapers that can be used to switch between arbitrary beam shapes. We specifically ...
