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. [...]

Diffractive shadowing of coherent polarization radiation

We report on the study of shadowing of electromagnetic fields radiated in the Terahertz (THz) region from two consecutive sources of coherent diffraction and transition radiation. In these conditions, the formation length is predicted to be $\leq$ 100 m, and shadowing effects should result in an almost complete suppression of radiated fields within distances of the order of tens of centimeters.

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.

Noninvasive bunch length measurements exploiting Cherenkov diffraction radiation

We present the observation and the detailed investigation of coherent Cherenkov diffraction radiation (CChDR) in terms of spectral-angular characteristics. Electromagnetic simulations have been performed to optimize the design of a prismatic dielectric radiator and the performance of a detection system with the aim of providing longitudinal beam diagnostics.

Recent results using incoherent Cherenkov Diffraction Radiation for non-invasive beam diagnostics

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.
