Low Energy Accelerators





After the 20 years operation, the PNPI electrostatic accelerator and neutron generator continue to be ones of the most active facilities in investigations of materials by the nuclear physics methods. The simultaneous use of these methods (a proton induced X - ray emission, a Rutherford backscattering spectrometry and a nuclear action analysis) in the single installation allows to obtain unique, detail and precise information on a composition, a structure and properties of investigated sample from one experiment. These techniques permit to investigate thin films, near surface region of solids, thin wires one its destruction.
The main directions of investigations include:
research of high temperature superconductivity materials (films, crystals, ceramics),
investigation of fullerene containing materials,
research of metal nanoclusters in dielectric matrices of hydrogenated amorphous carbon -CH,
investigation of lithium diffusion mechanism and intercalation processes in nanoporous carbon materials,
aging investigations of straw drift-tubes, proposed for experiments on Large Hadron Collider (LHC) and Deutches Electronen Synchrotron (DESY).
