SYSTEM FOR DETERMINING THE SPECIFIC HEAT OF LIQUID HELIUM AT DIFFERENT PRESSURES

Abstract

ABSTRACT A system (100) for determining the specific heat of liquid helium at different pressures, comprising: a pressure control module for varying and maintaining specific pressures; a temperature measurement module configured to accurately measure the temperature of the liquid helium; a heat input module to introduce a known amount of heat to the liquid helium; and a data analysis module for calculating the specific heat based on the temperature change resulting from the heat input. <>

Specification

Description:FIELD OF THE DISCLOSURE
[0001] This invention generally relates to a field of cryogenics and, in particular, to a method and system for determining the specific heat of liquid helium at different pressures.
BACKGROUND

[0002] The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.
[0003] Liquid helium, due to its unique properties, is widely used in various scientific and industrial applications, particularly in fields requiring extremely low temperatures, such as superconductivity, cryogenics, and low-temperature physics.
