Cherenkov Diffraction Radiation as a tool for beam diagnostics
/ Lefèvre, Thibaut (CERN) ; Alves, Diogo (CERN) ; Apollonio, Marco (Diamond Light Source) ; Aryshev, Alexander (KEK, Tsukuba) ; Bergamaschi, Michele (CERN) ; Billing, Michael (Cornell U., CLASSE) ; Bleko, Vitol'd (Tomsk Polytechnic U.) ; Bobb, Lorraine (Diamond Light Source) ; Bordlemay Padilla, Yadira (Cornell U., CLASSE) ; Conway, Joseph (Cornell U., CLASSE) et al.
During the last three years, the emission of Cherenkov Diffraction Radiation (ChDR), appearing when a relativistic charged particle moves in the vicinity of a dielectric medium, has been investigated with the aim of providing non-invasive beam diagnostics. ChDR has very interesting properties, with a large number of photons emitted in a narrow and well-defined solid angle, providing excellent conditions for detection with very little background. [...]

Recent Results on Non-invasive Beam Size Measurement Methods Based on Polarization Currents
/ Mazzoni, Stefano (CERN) ; Aryshev, Alexander (KEK, Tsukuba) ; Bergamaschi, Michele (CERN) ; Billing, Michael (Cornell U.) ; Bleko, Vitol'd (Tomsk Polytechnic U.) ; Bobb, Lorraine (Diamond Light Source) ; Conway, Joseph (Cornell U.) ; Forster, Michael (Cornell U.) ; Fuentes, Yadira (Cornell U.) ; Jones, Owain Rhodri (CERN) et al.
We present recent results on non-invasive beam profile measurement techniques based on Diffraction Radiation (DR) and Cherenkov Diffraction Radiation (ChDR). Both methods exploit the analysis of broadband electromagnetic radiation resulting from polarization currents produced in, or at the boundary of, a medium in close proximity of a charged particle beam.

Non-invasive Beam Diagnostics with Cherenkov Diffraction Radiation
/ Lefèvre, Thibaut (CERN) ; Bartnik, Laurel (Cornell U.) ; Bergamaschi, Michele (CERN) ; Billing, Michael (Cornell U.) ; Bleko, Vitol'd (Tomsk Polytechnic U.) ; Bobb, Lorraine (Diamond Light Source) ; Padilla Fuentes, Yadira (Cornell U.) ; Conway, Joseph (Cornell U.) ; Forster, Michael (Cornell U.) ; Jones, Owain Rhodri (CERN) et al.
Based on recent measurements of incoherent Cherenkov Diffraction Radiation (ChDR) performed on the Cornell Electron Storage Ring, we present here a concept for the centering of charged particle beams when passing close to dielectric material. This would find applications as beam instrumentation in dielectric capillary tubes, typically used in novel accelerating technologies, as well as in collimators using bent crystals for high-energy, high-intensity hadron beams, such as the Large Hadron Collid-er or Future Circular Collider.

Cherenkov Diffraction Radiation From Long Dielectric Material: An Intense Source of Photons in the NIR-THz Range
/ Lefèvre, Thibaut (CERN) ; Bergamaschi, Michele (CERN) ; Billing, Michael (Cornell U., CLASSE) ; Bobb, Lorraine (Garsington, Oxfordshire) ; Conway, Joseph (Cornell U., CLASSE) ; Jones, Owain Rhodri (CERN) ; Karataev, Pavel (Royal Holloway, U. of London) ; Kieffer, Robert (CERN) ; Mazzoni, Stefano (CERN) ; Shanks, James (Cornell U., CLASSE)
This paper presents the design on the Cornell Electron Storage Ring (CESR) of an experimental set-up to meas-ure incoherent Diffraction Cherenkov Radiation (DChR) produced in a 2 cm long SiO2 radiator by a 2.1 GeV elec-tron beam. The electron beam is circulating at a distance of few mm from the edge of the radiator and the DChR photon output power is expected to be significantly higher than the diffraction radiation power emitted from a metal-lic slit of similar aperture.

Development of a Versatile OTR-ODR Station for Future Linear Colliders

In order to study the feasibility of Optical Transition (OTR) and Diffraction (ODR) Radiation based profile measurement for the future electron-positron linear colliders (ILC, CLIC) a new dedicated instrument is under development at CERN to be installed in KEK-ATF2 beam line in fall 2015. To optimize sensitivity to micron and sub-micron beam sizes, we plan to observe ODR/OTR in the visible-UV wavelength range, down to approximately 150 nm. [...]

ZEMAX Simulations for an Optical System for a Diffraction Radiation Monitor at CesrTA

Diffraction Radiation (DR) is produced when a relativistic charged particle moves in the vicinity of a medium. The target atoms are polarized by the electric field of the charged particle, which then oscillate thus emitting radiation with a very broad spectrum. [...]

Transition Radiation (TR) and Diffraction Radiation (DR) are produced when a relativistic charged particle moves through a medium or in the vicinity of a medium respectively. The target atoms are polarised by the electric field of the charged particle, which then oscillate thus emitting radiation with a very broad spectrum. [...]

Electron Cloud at Low Emittance in CesrTA
/ Palmer, Mark (Cornell U., CLASSE) ; Alexander, James (Cornell U., CLASSE) ; Billing, Michael (Cornell U., CLASSE) ; Calvey, Joseph (Cornell U., CLASSE) ; Conolly, Christopher (Cornell U., CLASSE) ; Crittenden, James (Cornell U., CLASSE) ; Dobbins, John (Cornell U., CLASSE) ; Dugan, Gerald (Cornell U., CLASSE) ; Eggert, Nicholas (Cornell U., CLASSE) ; Fontes, Ernest (Cornell U., CLASSE) et al.
The Cornell Electron Storage Ring (CESR) has been reconfigured as a test accelerator (CesrTA) for a program of electron cloud (EC) research at ultra low emittance. The instrumentation in the ring has been upgraded with local diagnostics for measurement of cloud density and with improved beam diagnostics for the characterization of both the low emittance performance and the beam dynamics of high intensity bunch trains interacting with the cloud [...]
