C-09: Accelerators and detectors
Poster presentation (105min)
The challenge of cooldown the huge cold mass up to 1400 tons (dominated by iron) to 4.5 K is addressed as one of the most important features for Super-FRS cryogenics at FAIR. For such large cold mass the precooling with LN2 is necessary due to the reason that approximately ~80% of the cool down load is from 300K to 80K. The capacity of the LN2 precooler at 80 K as well as the 4.5 K cooling...

Poster presentation (105min)
Regenerator, a most important part of pulse tube refrigerator (PTR), must be carefully designed especially when working at high frequency and ultra-low temperature. In process of selecting regenerator materials, much attention is paid on the heat capacity of regenerator materials, while thermal conductivity is always omitted. In this paper, an effort will be made on explaining how thermal...

Poster presentation (105min)
The accumulated oxygen in liquid hydrogen is a big risk for storage. The oxygen and nitrogen molecules will be cooled down from gas to solid when air enters the liquid hydrogen. The intermolecular attractive force can influence the accumulation of oxygen and nitrogen molecules. The contents of molecule clusters can be different from each other. This paper studies the accumulation of air in...

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...

C-14: New devices and novel concepts
Poster presentation (105min)
As a highly effective two-phase cooling technique, a cryogenic heat pipe can transport several orders of magnitude larger heat loads than heat conduction of solids such as copper, and it has been used widely for cooling of superconducting magnets, electronic devices and harvesting energy. Among the different types of heat pipes, the cryogenic pulsating heat pipe is a new-type heat pipe which...

C-06: Heat transfer and thermo-physical properties of solids and fluids
Poster presentation (105min)
To maintain the temperature and pressure in liquid oxygen tanks, the cryogenic tanks must be thermally insulated to prevent or minimize heat transfer from the ambient environment. Frost will form on the wall of the cryogenic tanks if the liquid oxygen tanks have been left bare. The frost layer, which has low thermal conductivity and obvious heat insulation effect, is a porous media consisting...

Poster presentation (105min)
Using graphite as matrix material and copper alloy as infiltration material, we prepared a copper-graphite composite by press impregnation method. Some physical properties of the composite, such as hardness, thermal conductivity coefficient, linear coefficient of expansion, density and porosity, have been tested and compared with the matrix material. The micrographs obtained by the...

Evaporation rate is an important technological parameter to evaluate the performance of a multilayer cryogenic vessel, especially for storing liquid hydrogen due to the low boiling point of the hydrogen. When the nitrogen is used to as the test fluid to evaluate the evaporation rate of the multilayer liquid hydrogen vessel especially for the larger volume vessel which can not directly use the...

ABSTRACT: The function of the cryogenic condenser is to liquefy nitrogen gas or gases like oxygen, methane etc. It has been possible to develop successfully such a critical low temperature condenser from electrolytic grade copper bar having diameter 150mm and length 300 mm. Fabrication is very complicated as its contain160 slots of 0.5 mm length and depth 56 mm which is maintained within 70...

Due to their firm structure, reliable performance and long-life, differential pressure flowmeters are still widely applied in the field of cryogenic fluid flow meter. However, cryogenic fluids comprise of lower saturation temperature and less vaporization latent heat. They are prone to cavitate in the process of throttling flow. In the present paper, liquid hydrogen is taken as the test fluid...

Self-pressurization transfer is used widely for transferring liquid hydrogen, where a fraction of the liquid in the storage vessel is vaporized and superheated throughout the vaporizer by exchanging heat with ambient air, and returned to pressurize the ullage volume of the storage vessel to expel the liquid hydrogen. In this paper the pressurization performance of the self-pressurization...
