Temperature Control

Definition

Temperature control refers to the management of temperature within a specified range to ensure optimal performance and reliability of materials and devices, especially in superconducting applications. Effective temperature control is crucial for maintaining the superconducting state of materials, as even slight variations can lead to loss of superconductivity and affect the functionality of devices. It involves various techniques and strategies aimed at preventing thermal fluctuations that could compromise the integrity and performance of superconducting devices during their fabrication and operation.
