“…For example, the expected heat load of Super-FRS (separating device) is 1770 W at 4 K, including a design factor of 1.5 [6]. Cooling capacity of the entire cryogenic system of accelerator is approximately 34.9 kW at 4 K [7].…”

Superconducting magnets in the SIS100 particle accelerator require the supply of liquid helium and electric current. Both are transported with by-pass lines designed at Wrocław University of Technology. Bus-bars used to transfer an electric current between the sections of the accelerator will be encased in a steel shell. Eddy currents are expected to appear in the shell during fast-ramp operation of magnets. Heat generation, which should be limited in any cryogenic system, will appear in the shell. In this work the amount of heat generated is assessed depending on the geometry of an assembly of the bus-bars and the shell. Numerical and analytical calculations are described. It was found that heat generation in the shell is relatively small when compared to other sources present in the accelerator and its value strongly depends on the geometry of the shell. The distribution of eddy currents and generated heat for different geometrical options are presented. Based on the results of the calculations the optimal design is proposed.

“…Cooldown of the 1,100 tons cold mass down to 4.5 K has been addressed as one of the great challenges for the Super-FRS cryogenics. For the iron dominated cold mass the advantage of using LN2 precooling at 80 K is obvious in order to have a reasonable cooldown time of three to four weeks down to 4.5 K operation temperature [6]. In the context of the last decades, Romanian's future energy system is uncertain.…”

Cryogenics was developed especially after 1990, when Romania's economy has become a free economy. Specialists in the field of cryogenics were only a few and Romanian contribution in research and development of Cryogenics were almost nonexistent. After 1990, development of the main industrial objectives of the country, required the construction and reconstruction of large and modern facilities cryogenic liquefaction of gases, such as ASU Galati GOX 60,000 Nm3 /h in 2010 or Hydrogen Factory - 15,000 Nm3 H2, Petrobrazi, Ploiesti, in 2014. Achieving these plants contribute to the development of scientific research, technological progress in improved editing and design schemes.
