282. Upgrade of the cryogenic infrastructure of SM18, CERN main test facility for superconducting magnets and RF cavities

Dr Antonio Perin (CERN)

12/07/2017, 14:00

Contributed Oral Presentation

SM18 is CERN main facility for testing superconducting accelerator magnets and superconducting RF cavities. Its cryogenic infrastructure will have to be significantly upgraded in the coming years, starting in 2019, to meet the testing requirements for the LHC High Luminosity project and for the R&D program for superconducting magnets and RF equipment until 2023 and beyond. This article...

139. Real-Time Helium Inventory Monitoring of JLab Cryogenic Systems

Dr Nusair Hasan (Thomas Jefferson National Accelerator Facility)

12/07/2017, 14:30

Contributed Oral Presentation

There are five cryogenic plants at Jefferson Lab which support the LINAC, experiment hall end-stations and test facility. The majority of JLab’s helium inventory, which is around 10 tons, is allocated in the LINAC cryo-modules, with the majority of the balance of helium distributed at the cryogenic plant level mainly as stored gas and liquid for stable operation. Due to the organic evolution...

113. Applicability of ASST-A Helium Refrigeration System for JLab End Station Refrigerator Upgrade

Dr Nusair Hasan (Thomas Jefferson National Accelerator Facility)

12/07/2017, 14:45

Contributed Oral Presentation

The MØLLER experiment at Jefferson Lab (JLab) is a high power (5 kW) LH2 target scheduled to be operational in the 12 GeV era. At present, cryogenic loads and targets at three of JLab’s four experimental halls are supported by the End Station Refrigerator (ESR) - a CTI/Helix 1.5 kW 4.5 K refrigerator. It is not capable of supporting the high power target load and a capacity upgrade of the ESR...

433. 4K Helium Refrigerators for Commercial Superconducting Accelerators

Joseph Yancey (Niowave Inc.)

12/07/2017, 15:00

Contributed Oral Presentation

At Niowave, Inc., superconducting electron accelerators are being built to tackle America's high-tech challenges in fields as diverse as health care and national security. To operate these accelerators, we have collaborated with Linde Cryogenics to develop the refrigeration infrastructure required. Niowave operates two standard model compact, mobile, standalone cryogenic systems. The larger...

223. Outsourcing strategy and tendering methodology for the operation and maintenance of CERN’s cryogenic facilities

Dr Luigi Serio (CERN)

12/07/2017, 15:15

Contributed Oral Presentation

CERN operates and maintains the world largest cryogenic infrastructure ranging from ageing but well maintained installations feeding detectors, test facilities and general services, to the state-of-the-art cryogenic system serving the flagship LHC machine complex. A study was conducted and a methodology proposed to outsource to industry the operation and maintenance of the whole cryogenic...

462. Model-based minimization algorithm of a supercritical helium loop consumption subject to operational constraints

Dr François BONNE (CEA/SBT), Christine Hoa (CEA SBT)

12/07/2017, 15:30

Contributed Oral Presentation

Supercritical helium loops at 4.2 K are the baseline cooling of tokamaks superconducting magnets (JT-60SA, ITER, DEMO, etc.). This loops work with cryogenic circulators that force a supercritical helium flow through the superconducting magnets in order that the temperature stay below the working range all along their length. This paper shows that a supercritical helium loop associated with a...
