Linac-Beam Characterizations at 600 MeV Using Optical Transition Radiation Diagnostics
Selected optical diagnostics stations were upgraded in anticipation of low-emittance, bright electron beams from a thermionic rf gun or a photoelectric rf gun on the Advanced Photon Source (APS) injector linac. The upgrades include the installation of optical transition radiation (OTR) screens, transport lines, and cameras for use in transverse beam size measurements and longitudinal profile me...
متن کاملBeam 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 کاملConsiderations on the Diffraction Limitations to the Spatial Resolution of Optical Transition Radiation
The interest in using optical transition radiation (OTR) in high energy (multiGeV) beam diagnostics has motivated theoretical and experimental investigations on the limitations brought by diffraction on the attainable resolution. This paper presents calculations of the diffraction effects in an optical set-up using OTR. The OTR diffraction pattern in a telescopic system is calculated taking int...
متن کاملResolution power of optical transition radiation: Theoretical considerations
The spatial resolution power of Optical Transition Radiation (OTR), applied to beam pro®le measurements at high Lorentz factor c, is studied taking into account diraction and self-diraction eects. Microscopic and macroscopic points of view about the dierent geometrical natures of the forward and backward OTR sources are presented. Properties of the impact parameter pro®le I(b) of the OTR em...
متن کاملApplication of Optical Diffraction Radiation to a Non-invasive Low-emittance High-brightness Beam Diagnostics
A simple approach for the beam size mesurements with optical diffraction radiation from a slit target is presented. The estimations show that it is possible to measure the beam size with a resolution of about ~1μm. We developed a new approach for calculating diffraction radiation characteristics from a rectangular finite size target with a rectangular opening in it to be able to estimate the in...
