The cryogenic system for the KSTAR superconducting magnets has been commissioned. It consists of a cold box, distribution boxes (DB) and cryogenic transfer lines. The cold box and DB #1 provide 600 g/s of supercritical helium to cool the superconducting (SC) magnets, their SC bus-lines, and the magnet support structures. It also provides 17.5 g/s of liquid helium to the current leads and suppli...
Exploration of the benefit of cryotreatment for achieving improvement in corros ion rate of mild steel is a topic of current research interest. This study is concerned with the effect of deep cryogenic treatment at temperature of -193 0 C on the corrosion rate and mechanical properties. A series of corrosion rate tests have been carried out to cryotreated samples. The specimen were divided into...
A principal goal of the ongoing TESLA superconducting linac project is the production of affordable cryostats that still meet stringent requirements for alignment, vibration and heat leak. Each cryostat contains 8 superconducting RF cavities cooled to 1.8 K, a quadrupole magnet package cooled to 4.5 K, thermal shields cooled to 70 K and 4.5 K, active and passive magnetic shielding, cryogenic se...
Ti-6Al-4V α/β titanium alloy is used in biomedical applications to produce artificial joints due its excellent osseointegration property, high corrosion resistance, low density, and Elasticity modulus compatible with bone structure. Considering the usage area, expected have tensile properties wear resistance. In this study, aging treatment a combination of cryogenic were applied obtain Cryogeni...
Joule-Thomson cooling systems are used in refrigeration and liquefaction processes. There are extensive studies on Joule-Thomson cryogenic systems, but most of them coverage steady state conditions or lack from experimental data. In the present work, transient thermal behavior of Joule-Thomson cooling system including counter current helically coiled tube in tube heat exchanger, expansion valve...
