  Storage ring of LEPTA facility was commissioned in September 2004 and was under development up to now. The positron injector has been constructed in 2005-2010, and beam transfer channel – in 2011. By the end of August 2011 experiments on electron and positron injection into the ring have been started. The last results are presented in this report: studies of e+/e dynamics in trap, e+ beam in the ring, LEPTA upgrade (vacuum, e+ source with cryocooler), Channel for PAS.

  Electron cooling system (ECS) of the NICA collider is designed to form the required parameters of the ion beam at energy of the experiment in the range of 1 - 4.5 GeV/amu that requires energy cooling electrons from 0.5 to 2.5 MeV. To achieve the required energy of the electrons all elements of ECS are placed in tanks filled with sulfur hexafluoride (SF6) under pressure of 6 atm. For testing items ECS elements the test bench "Recuperator" is used. This paper presents the results of testing the prototype elements of the ECS and the first results of technical design of ECS.
