Radiation technology facilities based on electron beam accelerators at the branch of the Federal State Unitary Enterprise (FSUE) "Karpov Institute of Physical Chemistry": manufactured products and promising developments.
At present five EB accelerator-based technological facilities are operated at the Karpov Institute to solve the following tasks: manufacture of various commercial products (foamed polyethylene, pipeline insulation, pipe products for electrical engineering, composite materials), scientific re- search and development of promising radiation-chemical technologies.

Status of BINP proton tandem-accelerator for explosive detection by NRA method and for boron neutron-capture therapy.
Status of original 2.0 MeV, 10 mA proton tandem-accelerator with vacuum insulation is pre- sented. The accelerator is intended to be used in facilities generating resonance gamma rays for explosives detection and epithermal neutrons for boron neutron-capture therapy of brain tumors. Steady-state sectioned rectifier from industrial ELV-type electron accelerator is used as a high voltage source for the accelerator. A dc high-current negative ion source has been developed for injection into the tandem. In the tandem accelerator there is set of nested potential electrodes with openings which form a channel for accelerated negative ion beam and subsequently for pro- ton beam after stripping gas target. The electrodes are fixed on a high voltage feedthrough insu- lator though which required potentials are applied to them from the rectifier by means of resistor voltage divider. In the paper the first experimental results obtained with vacuum insulated tan- dem accelerator are also given. Keywords: vacuum insulation tandem accelerator, gamma reso- nance absorption, boron neutron capture therapy.
