Shvedunov² ¹Lebedev Physical Institute of Russian Academy of Sciences, Moscow, Russia ²Skobeltsyn Institute of Nuclear Physics, Lomonosov Moscow State University, Moscow, Russia Abstract The design of 55 MeV Race-Track Microtron (RTM) with pulse current up to 50 mA has been completed and now accelerator is under construction. We present the general scheme of this microtron, the basic results of computer simulation, the parameters of the RTM components and describe engineering design and status of the machine. ª – corresponding author |

PARTIALLY COHERENT EM RADIATION OF AN ELECTRON BUNCH |

M.A. Gorbunovª, A.N. Lebedev Lebedev Physical Institute of Russian Academy of Sciences, Moscow, Russia Abstract Peculiarities of electromagnetic radiation of a spatially non-uniform bunch of electron radiators are considered starting with a general discussion of their temporal and spatial coherence. The obtained spectral-angular characteristics permit to define a coherent part of the total radiation losses of the bunch. Their dependencies on the radiators density within the bunch, including a case of low particles number per one wavelength, permit to estimate the ultimate limit of possible coherent effects in rarified beams. The presented 3D visualization reveals radiators interference and permits to exclude a "useful" part of coherent radiation within a narrow angle along the particles relativistic velocity. ª – corresponding author |
