• Ho-Myung Chang (Hong Ik University)

32. Specification of ESS Accelerator Cryoplant

Dr xilong wang (European Spallation Source ESS AB)

09/07/2014, 16:00

C-01: Large scale refrigeration, liquefaction

Oral presentation (15min)

The European Spallation Source (ESS) is a neutron-scattering facility being built with extensive international collaboration at Lund, Sweden. The ESS accelerator will deliver protons with 5 MW of power to the target at 2.0 GeV, with a nominal current of 62.5 mA. The superconducting part of the accelerator is about 300 meters long and contains 43 cryomodules. The ESS accelerator cryoplant will...

C-01: Large scale refrigeration, liquefaction

Oral presentation (15min)

Helium plays a critical role in a wide array of product. It is used for a number of industrial and medical applications, including MRI scanners, semiconductors, fiber optic cable. The helium market is expected to grow steadily, by an average of +4% a year. With the largest proven helium reserves, Qatar decided to meet the world helium rising demand by building a second Helium Recovery Unit...

110. ENGINEERING, PROCUREMENT, AND COMMISSIONING OF THE NEW HELIUM LIQUEFACTION FACILITY FOR GAZPROM GAZENERGOSET IN ORENBURG, RUSSIA

Mr Klaus Ohlig (Linde Kryotechnik AG)

09/07/2014, 16:30

C-01: Large scale refrigeration, liquefaction

Oral presentation (15min)

In 2012, Linde Kryotechnik AG, Switzerland, received the contract for supply of a helium liquefaction plant with a capacity of 500 l/h for Gazprom Gazenergoset’s Orenburg facility in Russia. The plant will deliver liquid helium mainly to the Russian market and replaces existing helium liquefaction plants which have been operated by Cryor. Whereas Linde Kryotechnik AG was in charge of the...

323. Development of a Ground Operations Demonstration Unit for Liquid Hydrogen at Kennedy Space Center

Dr William Notardonato (NASA KSC)

09/07/2014, 16:45

C-01: Large scale refrigeration, liquefaction

Oral presentation (15min)

NASA operations for handling cryogens in ground support equipment have not changed substantially in 50 years, despite major technology advances in the field of cryogenics. NASA loses approximately 50% of the hydrogen purchased because of a continuous heat leak into ground and flight vessels, transient chilldown of warm cryogenic equipment, liquid bleeds, and vent losses. NASA KSC needs to...

92. Overview on AL.AT cryogenic solutions under 4.5K

Simon CRISPEL (Air Liquide Advanced Technologies)

09/07/2014, 17:00

C-01: Large scale refrigeration, liquefaction

Oral presentation (15min)

Through its history from 70’s, Air Liquide Advanced Technologies developed various cryogenic solutions (cold machines and cryogenic refrigeration) to support superconductivity applications. Thanks to a proven reliability pointed out in particular by the huge refrigeration architecture at LHC, CERN, very cold cryogenics has become “usual”. Reach very cold temperature more favorable to...

214. Cryogenic cooling of the cold neutron source at ESS

Mr John Jurns (European Spallation Source ESS AB)

09/07/2014, 17:15

C-01: Large scale refrigeration, liquefaction

Oral presentation (15min)

The European Spallation Source (ESS) neutron spallation project currently being designed will be built outside of Lund, Sweden. The ESS design includes three helium cryogenic plants, providing cryogenic cooling for the proton accelerator superconducting cavities, for the target cold neutron source, and for the ESS instrument suite. Supercritical hydrogen circulates through and cools the target...

69. JT-60SA: status of Cryogenic System and focus on Cryogenic Rotating Machines

Cecile Gondrand (Air Liquide Advanced Technologies)

09/07/2014, 17:30

C-01: Large scale refrigeration, liquefaction

Oral presentation (15min)

The Cryogenic System for JT-60SA must provide cold power to 5 circuits of the Tokamak: Toroidal Field coils (TF) and structures at 4.4K, Central Solenoid and Equilibrium Field coils (CS+EF) at 4.4K, cryopumps at 3.7K, thermal shields (TS) at 80K and current leads at 50K. The process choice was driven by the decision to feed the first two circuits (TF and CS+EF) using two supercritical helium...

42. CURRENT STATUS OF THE MODIFICATIONS OF THE FORMER HERA CRYOGENIC PLANT FOR THE XFEL FACILITY

Mr Hanspeter Wilhelm (Linde Kryotechnik AG)

09/07/2014, 17:45

C-01: Large scale refrigeration, liquefaction

Oral presentation (15min)

The Hadron-Electron-Ring-Accelerator (HERA) at the German Electron Synchrotron (DESY) in Hamburg, Germany, was in operation between 1990 and 2007. The required cooling capacity for the superconducting magnets was provided by a cryogenic system consisting of three identical helium refrigeration plants. Due to the implementation of the X-ray free electron laser European XFEL, the existing HERA...

41. DESIGN, PROJECT EXECUTION, CONSTRUCTION AND COMMISSIONING OF THE 1.8K SUPERFLUID HELIUM REFRIGERATION SYSTEM FOR SRF CRYOMODULE TESTING

Mr Philipp Treite (Linde Kryotechnik AG)

09/07/2014, 18:00

Oral presentation (15min)

The Fermilab Cryomodule Test Facility (CMTF) provides a test bed to measure the performance of superconducting radiofrequency (SRF) cryomodules (CM). These SRF components form the basic building blocks of future high intensity accelerators such as Project X, International Linear Collider (ILC), and a Muon Collider. Linde Kryotechnik AG and Linde Cryogenics have designed, constructed and...
