TL;DR: The first experimental results of temperature control for this cryostat were presented and the ultra-high precision temperature control in the range of 5-25 K has been fully realized, which was the temperature instability of 0.022 mK at 25 K, almost the best reporting result in the world and showed its great potential in SPRIGT.
Abstract: Single-pressure refractive-index gas thermometry (SPRIGT) is a new type primary thermometry jointly developed by TIPC of CAS in China and LNE-Cnam in France. To realize a competitive uncertainty of 0.25 mK for the thermodynamic temperature measurement, a cryogen-free cryostat with high-stability better than 0.2 mK should be designed. This paper presented the first experimental results of temperature control for this cryostat. To realize this objective, multi-layer radiation shields combined with a thermal-resistance method were used to isolate the thermal-noise from surroundings. Besides, a new temperature control method based on a gas-type heat switch and proportional-integral-derivative control method was proposed, which was applicable to different temperature ranges by changing the working modes of the heat switch. After optimizing, the ultra-high precision temperature control in the range of 5–25 K has been fully realized, which was the temperature instability (with standard deviation) of 0.021 mK at 5.0 K, 0.05 mK at 5.7 K, 0.042 mK at 7.4 K, 0.029 mK at 14.3 K, and 0.022 mK at 25 K with the sampling time of 0.8 s. This was almost the best reporting result in the world and showed its great potential in SPRIGT.

TL;DR: In this paper, a strawberry-like core-shell structured aluminum oxide/tannic acid-ferric ion/silver (Al2O3/TA-Fe3+/Ag) nanoparticles (NPs) were incorporated into nitrile butadiene rubber (NBR) matrix to obtain thermally conductive composites.

TL;DR: A new proper orthogonal decomposition reduced-order model for fluid flow and heat transfer processes in a fractured geothermal reservoir is proposed, developed by projecting the discrete matrix equations instead of the primary governing equations onto the low-dimensional space spanned by the pressure and temperature basis functions.

TL;DR: In this article, a 2.93 fb(-1) data sample of e(+)e(-) collisions, recorded at a center-of-mass energy of 3.773 GeV with the BESIII detector operated at the BEPCII collider, was analyzed.
Abstract: By analyzing a 2.93 fb(-1) data sample of e(+)e(-) collisions, recorded at a center-of-mass energy of 3.773 GeV with the BESIII detector operated at the BEPCII collider, we report the first observa ...
