Channeling Effect in Polycrystalline Deuterium-Saturated CVD Diamond Target Bombarded by Deuterium Ion Beam

At the ion accelerator HELIS at the LPI, the neutron yield is investigated in DD reactions within a polycrystalline deuterium-saturated CVD diamond, during an irradiation of its surface by a deuterium ion beam with the energy less than 30 keV. The measurements of the neutron flux in the beam direction are performed in dependence on the target angle, \b{eta}, with respect to the beam axis. These measurements are performed using a multichannel detector based on He3 counters. A significant anisotropy in neutron yield is observed, it was higher by a factor of 3 at \b{eta}=0 compared to that at \b{eta} = +-45°. The possible reasons for the anisotropy, including ion channeling, are discussed.

Observation of neutron bursts produced by laboratory high-voltage atmospheric discharge

Data on the observation of neutron bursts in the process of high-voltage discharge in the air at an average electric field strength ~ 1 MV/m and discharge current ~ 10 kA are presented. Two independent methods (CR-39 track detectors and plastic scintillation detectors) registered neutrons within the range from thermal energies up to the energies above 10 MeV with the flux of >= 1E6 neutrons per shot into 4π solid angle.

Nuclear emulsion with molybdenum filling for observation of $ββ$ decay

The usage of nuclear emulsion with molybdenum filling for observation of $ββ$ decay are shown to be possible. Estimates for 1 kg of $^{100}$Mo with zero background give the sensitivity for the $0νββ$ decay of $^{100}$Mo at the level of $\sim 1.5\cdot 10^{24}$ y for 1 year of measurement.

Gas electron multiplier: performance and possibilities

The gas electron multiplier produced with the polyimide film 100 um thick. The maximum gas gain obtained with gas mixture Ar/CH4(91/9) was 5000. No decrease of gas gain with rates up to 2\cdot10^4 1/(mm^2 s) was observed. The possibility of operation of GEM with and without MSGC is discussed
