It is now calculated the system of parallel transfer PP electron beam in the channel 30 MeV. Part of the PP from the accelerator to the original window exists. To create only corresponding to manufacture PP stands to set them already made magnet and the target chamber, and a vacuum chamber to produce the output in the target window. Turning accelerator injector mode for generator Nestor initiated several improvements to enhance stability of the beam. The beam in the accelerator output has dimensions of 5 mm. across. The experiments showed the correctness of the installation of magnets and lenses injection channel. The measurements of the angular distributions of the fragments photofission 238U in the doorway and the giant resonance. The data of the angular distributions of the fragments photofission. The curves drawn through the points obtained in the experiment were adjusted according to the formula that describes the shape of the angular distribution. Fitted curves are in good agreement with the results of our experiment. The energy dependence of the anisotropy of the angular distribution of the fission fragments was obtained. It was found that with increasing energy gamma - ray anisotropy decreases, and the angular distribution of fission debris tends to be isotropic. The project of the gas helium target for the experiment as part of an international collaboration with TUNL. It created a prototype 10-ball spectrometer neutron activation type, and conducted its tests in neutron flux with e, ?, n -convector installed on the linear electron accelerator. Derived from ?, n-reactions neutron spectrum at the position close to the maximum expected, but it found the situation with considerable accuracy. Detected operating range of energy spectrometer 3 o 10-5 to 10 MeV. For different balls spectrometer found the values of neutron detection efficiency. Accordingly, the minimum measured neutron flux density, which may measure spectrometer. It is shown that by using a gamma spectrometer detector totally insensitive to background gamma radiation.
