| TUPG62 | X-Ray Smith-Purcell Radiation for Non-Invasive Submicron Diagnostics of Electron Beams Having TeV Energy | 494 |
|
||
| We present the general theory of X-ray Smith-Purcell radiation from ultrarelativistic beams proceeding from our earlier results. The theory covers also the case of oblique incidence of the beam to the target, which leads to the conical effect in spatial distribution of Smith-Purcell radiation and allows one to count the divergence of the beam; also, the analytical description of the incoherent form-factor of the beam is given. | ||

| WEPG62 | Incoherent and Coherent Polarization Radiation as Instrument of the Transversal Beam Size Diagnostics | 792 |

Polarization radiation, which includes diffraction radiation (DR), transition radiation (TR), Smith-Purcell radiation, and others, can be a good instrument for beam diagnostics. All information about the beam size is contained in the so-called form-factor of the beam. The form-factor represents the sum of two parts corresponding to the coherent and incoherent radiation*. Contrary to the general opinion the incoherent part does not always equal unity*, **. In this report we give theoretical description of the incoherent and coherent parts of the form-factor both for Gaussian and uniform distribution of the ultrarelativistic particles in the bunch*, ***. The theory constructed describes also the case of beam skimming the target, which leads to mixing of DR and TR***. We show that the incoherent part depends on the transversal size of the beam, and dependence differs for different distributions. The role of the incoherent part of the form-factor of the bunch for different parameters is discussed.
