  The high voltage electron cooling system for the NICA collider is now under development in the Budker Institute of Nuclear Physics (Russia). The aim of the cooler is to increase ion beams intencity during accumulation and to decrease both longitudinal and transverse emmitances of colliding beams during experiment in order to increase luminosity. Status of its development and results of tests of the cooler elements are described in the article.

  The status of Dipole of CR FAIR are presented, also key points of Dipole construction briefly described. CR FAIR is a special storage ring where the main emphasis is placed on efficient collecting and stochastic pre-cooling of intense beams of stable ions, rare isotopes or antiprotons. This DIpole is iron-based electromagnet with straight pole, sector form is realized by cutting ends. The maximum field value is 1.6 T. The integrated over the length of the magnet field quality as a function of radius is dB*l/B*l = ±1*10-4 with 190 mm good field region as required from the beam dynamics simulations. This challenging field quality is necessary mainly for precise experiments with ion beam in ISO regime. The first prototype has been manufactured at the end of 2020. Further we describe features of the dipole, measurements of magnetic field and ways for achieving of required field quality.
