چکیده
The Tera-eV Energy Superconducting Linear Accelerator (TESLA) is a 32 km long superconducting linear electron/positron collider of 500 GeV centre of mass energy (upgradeable to 800 GeV), presently in the planning phase at DESY [1,2]. About 21000 superconducting RF 9-cell cavities have to be cooled with superfluid helium at 2 K. The cavities are assembled in groups of 12 into about 16 m long cryo-modules. The roughly 1800 cryomodules are arranged in an underground accelerator tunnel in 12 about 2.5 km long cryo-units. Except for the 2 first cryo-units every 2 cryounits will be supplied from one refrigerator in a refrigerator hall above ground. The first two cryo-units have individual refrigerators in individual refrigerator

The Liquid Hydrogen System for the Mucool Test Area
A new MuCool test area (MTA) is under construction at Fermi National Accelerator Laboratory. This facility will house a cryo-system composed of a liquid hydrogen absorber enclosed in a 5 Tesla magnet. The total volume of liquid hydrogen in the system is 25 liters. Helium gas at 14 K is provided by an in-house refrigerator and will sub-cool the hydrogen system to 17 K. Liquid hydrogen temperatur...
متن کاملA magnetic resonance (MR) microscopy system using a microfluidically cryo-cooled planar coil.
We present the development of a microfluidically cryo-cooled planar coil for magnetic resonance (MR) microscopy. Cryogenically cooling radiofrequency (RF) coils for magnetic resonance imaging (MRI) can improve the signal to noise ratio (SNR) of the experiment. Conventional cryostats typically use a vacuum gap to keep samples to be imaged, especially biological samples, at or near room temperatu...
متن کاملT1 mapping in the rat myocardium at 7 tesla using a modified CINE inversion recovery sequence.
PURPOSE To evaluate the reproducibility and sensitivity of the modified CINE inversion recovery (mCINE-IR) acquisition on rats for measuring the myocardial T1 at 7 Tesla. MATERIALS AND METHODS The recently published mCINE-IR acquisition on humans was applied on rats for the first time, enabling the possibility of translational studies with an identical sequence. Simulations were used to study...
متن کاملStudy on Cryo-preservation of Theileria annulata Schizont Infected Cell Line Vaccine Strain S15
The purpose of this study was to examine the potential application of Sorbitol, Sucrose and Gelatin in combination with glycerol in order to Theileria annulata infected cell line cryo-preservation. The efficiency of the freezing methods was compared by assessing the viability and plating efficiency of cells after resuscitation, dilution and equilibration in cell culture medium. As a result, the...
متن کاملA Temperature-Stable Cryo-System for High-Temperature Superconducting MR In-Vivo Imaging
To perform a rat experiment using a high-temperature superconducting (HTS) surface resonator, a cryostat is essential to maintain the rat's temperature. In this work, a compact temperature-stable HTS cryo-system, keeping animal rectal temperature at 37.4°C for more than 3 hours, was successfully developed. With this HTS cryo-system, a 40-mm-diameter Bi2Sr2Ca2Cu3Ox (Bi-2223) surface resonator at...
