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.

Recent results using incoherent Cherenkov Diffraction Radiation for non-invasive beam diagnostics / Bergamaschi, Michele (CERN) ; Aryshev, Alexander (KEK, Tsukuba) ; Karataev, Pavel (JAI, UK ; Royal Holloway, U. of London) ; Kieffer, Robert (CERN) ; Lefèvre, Thibaut (CERN) ; Lekomtsev, Konstantin (JAI, UK ; Royal Holloway, U. of London) ; Mazzoni, Stefano (CERN) ; Potylitsyn, Alexander (Tomsk Polytechnic U.) ; Schloegelhofer, Andreas (TU Vienna)
When a relativistic charged particle travels at a short distance from the surface of dielectric material Cherenkov Diffraction Radiation (ChDR) is produced inside the dielectric. Recent observation of incoherent ChDR in the visible spectrum has opened the possibility of using this radiation for non-invasive beam size and position measurements. [...]

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.

Coherent Diffraction Radiation Longitudinal Beam Profile Monitor for CTF3 / Micheler, Maximilian (Royal Holloway, U. of London) ; Blair, Grahame A. (Royal Holloway, U. of London) ; Boorman, Gary (Royal Holloway, U. of London) ; Karataev, Pavel (Royal Holloway, U. of London) ; Lekomtsev, Konstantin (Royal Holloway, U. of London) ; Molloy, Stephen (Royal Holloway, U. of London) ; Corsini, Roberto (CERN) ; Dabrowski, Anne (CERN) ; Lefevre, Thibaut (CERN)
A setup for the investigation of Coherent Diffraction Radiation (CDR) from a conducting screen as a tool for noninvasive longitudinal electron beam profile diagnostics has been designed and installed in the Combiner Ring Measurement (CRM) line of the CLIC Test Facility (CTF3, CERN). In this report the status of the monitor development and results on the interferometric measurements of CDR spectra are presented [...]
