	A 4-8 MeV relativistic electron cooling system for the HESR storage ring, which is part of the future GSI facility FAIR, is needed to further boost the luminosity even with strong heating effects of high-density internal targets. In addition, the upgrade to 8 MeV of the relativistic electron cooler is essential for the future Electron Nucleon Collider (ENC at FAIR) project. Using the experience of the 2 MeV electron cooler at COSY, which has the highest energy of all coolers that were made based on the idea of magnetized cooling and transport of the electron beam up to now, a new concept for powering the solenoids at high voltage is proposed.

	For effective implementation of modern methods of X-raying required equipment complexes with increased requirements to the generator X-rays compared to conventional devices used in radiography. These requirements basically boil down to the fact that the radiation source along with small dimensions should provide at least 0.5 m from the target minimum exposure dose of about 10 mR for 1 with the appliance with a minimum area of the radiating surface of the target. These parameters are obtained by using X-rays generator based on high-current diode accelerating tube (AT) operating in the pulse-periodic regime at current amplitude of the accelerated electrons in the tube Im ~ 1 kA, pulse duration 1-10 ns and a maximum energy of electrons reaching several hundred keV The report presents the development of compact AT, which improved definition x-ray image is ensured by using a diode system with a coaxial geometry acceleration of electrons to the anode electrode internal target and explosive emission cathode.

	As a result of analysis conducted a transients of the 400 kV column intermediate electrode potential have been determined as one of the main processes responsible for change of beam phase-space portrait orientation during 200 mks, 50 Hz proton injector high voltage accelerating pulse. Beam transport simulation shows high sensitivity of the beam phase-space portrait orientation to variation of the intermediate electrode potential. It has been found that significant variation of this potential takes place due to transition process during a pulse in the capacitor-resistor voltage water divider of the accelerating tube. The divider capacities matching procedure has been performed. The beam emittance measurements results have shown that within the accuracy of observation the beam transverse phase-space portrait orientation remains constant during injector pulse with the accelerating tube voltage divider being compensated.

	Funding: Ministry of Education and Science of Russia (project RFMEFI57614X0181) At BINP for development of boron neutron capture therapy it is proposed and constructed the tandem accelerator with vacuum insulation, which is characterized by rapid acceleration of charged particles. Problems of high-voltage strength gaps due to the large stored energy and strong electrostatic lens are solved. It is obtained a stationary 1.6 mA 2 MeV proton beam having 0.1% energy monochromaticity and 0.5% current stability. It is clarified, that further increase of the proton current in the stable mode without breakdowns is limited by the accompanying current in the high-voltage gaps. It is proposed to make vacuum conditions better in the input of the accelerator using additional cryopump, to modernize argon stripping target by its tilting or shifting and to use differential pumping inside the high-voltage electrode. Obtaining of the 3 mA 2.5 MeV proton beam will allow us to conduct boron neutron capture therapy.
