	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.

	This paper presents the experimental and theoretical results of studying the unclosed shields made from LTS (low temperature superconductor) and HTS (high temperature superconductor) materials to obtain a homogeneous magnetic field in solenoids. There is a comparison of LTS and HTS shields,the construction peculiarities are described.

	The geometry of the induction electron accelerator, which will be used for high current acceleration, has been calculated. For the different currents values the optimum focusing magnetic field and has been obtained. Also a current in the compensative coil near the cathode has been calculated. The cathode electrode geometry was changing to achieve minimum beam oscillations during the acceleration.
