Accelerator UELV-10-10-T-1 is equipped with special system of injection and magnetic buncher with the purpose of generation picoseconds the beam duration 50 ps with the current 150A at energy 10 MeV for studying fluorescence and radiation-physical researches. For maintenance of the magnetic bunching the accelerator works in the mode of the reserved energy when duration of the pulse of injection (2,5 nanoseconds) is much less than time of filling of a wave guide energy (100 nanoseconds). At a pulse microwave of capacity 10 MW the energy which has been saved up in the wave guide, makes about 2 J. It provides an opportunity of a cutting collimator separately chosen bunch after scan of "package" by a rotary magnet. After an output from the accelerator the package electrons from 3÷5 bunches acts in magnetic buncher consisting of two electromagnets. In buncher the beam is scanning as "fan", and then focused. At a current of the beam 30 A in the pulse duration 2,5 nanoseconds distinction on energy between the adjacent bunches makes of 300 keV, that provides an opportunity of the cutting collimator the separate chosen bunch after space scanning with a rotary magnet. At a magnetic bunching electrons in "head" of a bunch have the big energy and are transported on trajectories with the big radius than "tail" electrons. Thus "compression" of the bunch on time is attain and accordingly the charge of a bunch increases.
