CryoST CryoHeSu DRAFT Experiments 0.180 SIS 100 14.28 SIS 300 3.72 30.13 Series- and String-tests 2.50 Liquid Supply 0.10 (20-40lLHe/h) Only CryoHeSu is a pure liquefier. The other cryo-facilities have to share refrigeration power, liquefaction and shield cooling power. These numbers are given in Table 2.4.35. Table 2.4.35: Split of liquefaction-, refrigeration- and shield cooling power in Watt at 4K. refrigeration / [W] liquefaction shield cooling static dynamic / [W] / [W] Cryo 1 1.230 1.500 660 (5,7g/s @ 4K) 800 Cryo 2 12.000 1.4000 920 (84g/s @ 50K) 3230 CryoST 800 900 600 200 Based on these figures an overall refrigerating capacity of 37 kW is planned at a temperature of 4.4 K. The installed capacity contains a safety factor of 1.5 which has to be considered due to: • required margin for the plant regulation, • buffer to compensate performance decreases during operation, • buffer to balance design risks on the experimental side. In addition a redundant compressor will be added in order to increase the availability of the helium plant. 2.4.A4.2.3 The Model Refrigerator A model refrigerator has been designed to get information on component sizes, number of compressors, and flow rates in different operation modes. Provisional data on power consumption for the specification of utility systems and approximate sizes of components for the building layouts are calculated.

Using a safety factor of 1.5 for the refrigeration loads a power consumption of 8.85 MW is expected for the FAIR refrigerators. 2.4.A4.2.4 Compressor Stations Central Compressor Station The FAIR cryo system (Cryo 1 and Cryo 2) will have a central compressor station located in the building 17a. In this building 5 high- and 7 low pressure compressors will be installed, including one redundant compressor for each pressure level. Also the oil removal system and the gas management system will be installed there. An overhead crane allows all service and repair work at the compressors. Compressor stations for CryoST and CryoHeSu These Compressors should be placed near to the coldboxes. 2.4.A4.2.5 Helium Storage The FAIR system will contain 11 t of helium when in full operation. If the system (or part of it) is warmed up the helium inventory will be stored as gas or liquid (1 litre liquid helium at 4 K corresponds to approx. 700 litre gaseous helium at room temperature). In case of a quench of the superconducting magnets helium will be expulsed out of the quenching coils. This helium will be collected in a helium recovery system. The FAIR helium system will have 7 gas storage tanks of 250 m³ each with a maximum storage pressure of 23 bars. These tanks will store 6 t of helium as a warm gas and will be located outside the buildings. Helium, which is evaporated during shutdown periods, will be either pumped to the gas storage tanks or condensed and collected in dewars. Two dewars for liquid helium will be installed with a storage volume of 20 m³. They contain about 5 t of helium. They are connected to the refrigerators by vacuum insulated lines. One liquid storage dewar will be placed at the location of each refrigerator cold box and would serve as a calorimeter/accumulator for the refrigeration/liquefaction acceptance tests. The 5 t liquid storage capacity allows the accumulation of liquid helium in periods of low refrig- 183
