Measurement of thermodynamic temperature between 5 K and 24.5 K with single-pressure refractive-index gas thermometry

We describe measurements of thermodynamic temperature in the range 5 K to 24.5561 K (the triple point of neon) using single-pressure refractive-index gas thermometry (SPRIGT) with 4He. In the wake of



Realization of an ultra-high precision temperature control in a cryogen-free cryostat.

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.

Resonance frequency measurement with accuracy and stability at the 10−12 level in a copper microwave cavity below 26 K by experimental optimization

Single-pressure refractive index gas thermometry (SPRIGT) is a novel primary thermometry technique, developed jointly by the Technical Institute of Physics and Chemistry (TIPC) of the Chinese Academy

Novel Nonrotational Piston Gauge with Weight Balance Mechanism for the Measurement of Small Differential Pressures

Piston gauges are well-known standard instruments in the field of pressure metrology. But it is difficult to use them for small differential pressure measurements, because the pressure must be

Characterization of a compact 200 MPa controlled clearance piston gauge as a primary pressure standard using the Heydemann and Welch method

Controlled clearance piston gauges are used as primary pressure standards at many national metrology institutes. The National Institute of Standards and Technology, in collaboration with the National

A Gas Pressure Scale Based on Primary Standard Piston Gauges

The National Institute of Standards and Technology (NIST) has redefined its gas pressure scale, up to 17 MPa, based on two primary standard piston gauges, and agreement in all cases to better than the expanded (k = 2) uncertainty of the difference between NIST and the other NMIs.
