Cryo 2 cold box and LHe storage Compressor hall Warm Gas Storage, LHe Storage • total mass of helium 8,230.8 kg • 2,000 kg will be stored as LHe • 6,230.8 kg will be stored as warm gas • 1 l helium are 125g • 2,000 kg 2,000/0.125=16,000 l • 6,239.8 kg GHe correspond to 2,232.34 m3at 35° C and 18 bar Basement part of CC, 26 * 100 m3 = 2,600 m3 There is space for 4 more tanks Holger Kollmus, CSCY

  26. Design Study on the Cryogenic Supply • The aim of this study was to propose a cryogenic infrastructure that can provide the required • needs in term of cool down time, redundancy and highest efficiency within the different operating • modes. The Studies were placed at ALAT and Linde KT. • Proposal on the cryogenic supply system for SIS100, SuperFRS and HADES/CBM experiments • Evaluation of various plant configurations for Cryo 1 (SuperFRS) • Evaluation of various plant configurations for Cryo 2 (SIS100) • Evaluation of a one plant solution: Cryo 0 • Evaluation of suitable compressor stations with regard to investment costs and high availability • Usage of Kaeser compressors? • All proposed plant configurations shall be compared with respect to reliability, operation and • investment costs (LN2 cooling?) • Elaboration of the expected minimal pressures on the cold end low pressure side • Estimate for the manpower required by GSI to follow-up during the design, installation and • commissioning phase • Estimation of the required space for the refrigerators and compressor systems • Provision of budget prices and delivery time for the refrigerators and the compressor systems Holger Kollmus, CSCY

  27. Refrigerator Options LN2 Version 1 SuperFRS SIS100 • Independent operation of SIS100 and SuperFRS • DB2 <-> DB3 not necessary or could be a cheap 4K supply, RT return line

  28. LN2 Version 4 Cryo 0 • Dependencies in SIS100 and SuperFRS cooling • DB2 <-> DB3 has to be a full featured/expensive transfer line • No Kaeser compressors

  29. Conclusion of the Studies • Both suppliers are in favor for two independent plants • Both suppliers recommend not to exceed 25 kW for a single plant • One plant solution + cool-down and warm-up unit (CWU) for the SuperFRS is a new option (due to the reduced heat loads)! • The 4K plant and the CWU could be from different suppliers • ALAT is proposing the independent shield cooling by a Turbo Brayton Cycle machine, which is not offered by LKT • Both considered options with and without permanent LN2 • significant investment cost reduction using LN2 only for SuperFRS plant (Kaeser compressors!) • Both studies confirm a suction pressure not lower than 1.22 bar • From both studies the available space for the refrigerator(s) and the cool-down and warm-up unit is still sufficient, allow the maintenance and later upgrade for SIS300

  30. Conclusion II, Cool-down and Warm-up Unit • Due to the cold mass of the SuperFRS of approximately 1300 t a dedicated pre-cooler with a heat capacity of 70 to 80 kW at 80 to 100 K is required. Since the warm-up of the SuperFRS magnets has to be performed independent of the SIS100 operation, this pre- cooler has to overtake in addition the warm-up in case of a single plant solution • The cooling is realized by a LN2 heat exchanger. During cool-down approximately one truck of LN2 per day over a range of three to four weeks is necessary • The cool-down and warm-up unit is switched off during normal operation but is usable for SuperFRS emergency cooling at 80 K with LN2

  33. Summary • Series Test Facility close to finalization • HeSu is running according to design specification • State of the art refurbishment of old plants successful • Studies on the cryogenic supply have been performed • Different cryo plant configurations are presently investigated • Decision for a one plant design
