In some experiments and applications there is need for large-area photosensitive detectors to operate at cryogenic temperatures. Nowadays, vacuum PMs are usually used for this purpose. We have developed special designs of planar photosensitive gaseous detectors able to operate at cryogenic temperatures. Such detectors are much cheaper PMs and are almost insensitive to magnetic fields. Results o...

Cryogenic treated high carbon high chromium alloy cold tool steels (D-3) are used in production of high performance dies, punches, blanking and punching tools, extrusion tools, etc. cryogenic treatment is a process of keeping the specimen in cold environment to increase its wear resistance and relieving its residual stresses. Due to its high hardness Wire Electric Discharge Machine (WEDM) seems...

Proteins are known to undergo a dynamical transition at around 200 K but the underlying mechanism, physical origin, and relationship to water are controversial. Here we report an observation of a protein dynamical transition as low as 110 K. This unexpected protein dynamical transition precisely correlated with the cryogenic phase transition of water from a high-density amorphous to a low-densi...

This paper discusses current plans and issues for exploration that involve the use of cryogenic transfer. The benefits of cryogenic transfer to exploration missions are examined. The current state of the art of transfer technology is reviewed. Mission concepts of operation for exploration are presented, and used to qualitatively discuss the performance benefits of transfer. The paper looks at t...

This paper describes data of an integrated process, cryogenic energy storage system combined with liquefied natural gas (LNG) regasification process. The data in this paper is associated with the article entitled "Conceptual Design and Exergy Analysis of Combined Cryogenic Energy Storage and LNG Regasification Processes: Cold and Power Integration" (Lee et al., 2017) [1]. The data includes the ...

In this work, the hypothesis of taking into account a specific thermoEMF to determine degree hardening cutting tool by cryogenic is put forward, which most convenient and important value from point view information content. As result studies improving mechanical characteristics instrumental materials treatment, values absolute thermo emf were revealed depending on temperature three obtained tar...

The MicroBooNE detector, to be located on axis in the Booster Neutrino Beamline (BNB) at the Fermi National Accelerator Laboratory (Fermilab), consists of two main components: a large liquid argon time projection chamber (LArTPC), and a light collection system. Thirty 8inch diameter Hamamatsu R5912-02mod cryogenic photomultiplier tubes (PMTs) will detect the scintillation light generated in the...

Abstract The influence of cryogenic and time (10, 24, 36, 48, 72 h) on the hardness, surface roughness, corrosion resistance properties AA5083-H111 alloy in 3.5 wt.% NaCl solution have been investigated. hardness property was analysed via Brinell measurement, measured electrochemically, while morphological studies were undertaken using SEM (scanning electron microscopy) atomic force microscopy ...

In the field of mechanical engineering, engineers are always looking for ways to improve the properties of materials. Cryogenic treatment of tooling steels is a proven technology to increase wear resistance and extend intervals between component replacements. The main idea of this paper is to apply Taguchi method to optimize cutting parameters in turning operation using cryogenic treated (CT) a...
