Thu-Po-3.2: Applications in Medical, Food, Power & Safety
- Caroline Fabre (CERN)
Recently, the increasing domestic power demand has led to an expansion of power facilities, resulting in a decrease in system impedance and subsequently causing an increase in fault currents. These fault currents surpass the interrupting capacity of conventional circuit breakers, leading to significant economic losses due to equipment malfunctions and damages. Although solutions like circuit...
In particle therapy of cancer, the radiation dose to tissues around the tumour can be reduced by employing a rotating gantry—a mechanical structure allowing the delivery of the beam to the patient from various angles. Gantries for ion therapy can benefit from the integration of superconducting magnets to minimize the size and weight of the machine. One significant challenge associated with the...
Freezing and cryopreservation are critical for maintaining the quality of organism, which has been widely used in food and medical industries. However, the generation of ice crystal during cryopreservation process can inevitably induce tissue injures and consequently damages the organism quality. Lowering the freezing point and accelerating the freezing rate are helpful to suppression the ice...
The Italian National Institute for Nuclear Physics (INFN) is currently involved in technological activities based on superconductivity. Two projects are running into the Test Facility for Large Superconducting Magnets and Superconducting Line at the Physics Department of the University of Salerno (Italy): both are devoted to the test and commissioning of superconducting devices, such as...
Due to merits of low loss, large capacity and compactness, concentric high temperature superconducting (HTS) cable has become an ideal solution to the of large-capacity power transmission in a narrow path. As the three phases in the concentric HTS cable are wounded one-by-one in the same former, the non-superconducting joints are concentrated in a short range. The same cooling method as the...
The current paper introduces the design and implementation of the Interlocks and Safety Functions implemented for operating the cryogenic system of the European Spallation Source (ESS) superconducting Linear Accelerator (LINAC), emphasizing the integration of individual cryomodules and valve boxes within a unified system controlled by a master CMDS (Cryomodules and Cryogenic distribution...
Abstract
Whole-body Cryotherapy (WBC) or cryostimulation stands as a prevalent and extensively employed recovery modality in the realms of sports and exercise medicine, especially post strenuous training and competitions. This practice involves brief exposures, usually lasting between 2 to 4 minutes, to extremely cold air, reaching temperatures of −110 °C and below. Individuals undergoing...
This paper studies, experimentally and analytically, on the characteristics of fly-wheel type uninterruptible power supply (FW-UPS) using high-temperature superconducting (HTS) induction machine (HTS-SIM). This study assumed that the SIM is iron-cored and composed of Cu wire stator windings and HTS rotor windings. The rotor windings consist of HTS wires embedded in iron rotor core and...
As part of the energy transition, the off-shore wind power market is booming with many very large-scale projects emerging or already in operation in Europe, Asia and America. Wind farms are commonly made up of several dozen turbines, the power of which has steadily increased in recent years, now exceeding more than 10 MW each, or soon even beyond.
Installed more than 150 meters above the...
Liquid Nitrogen/Fluorocarbon mixture would be an effective coolant and insulating medium of high-temperature superconducting (HTS) magnets and power devices, which may provide a cryogenic environment in the wide temperature range of 50 to 100K and serve as a liquid dielectric. In this paper, the gas-liquid-solid phase equilibrium, boiling heat transfer and insulation characteristics of the...
Helium cryogenic system has been widely used in large-scale scientific engineering fields utilizing superconducting technology, such as nuclear fusion, high-energy accelerator, and high-energy particle detector. Once suffering from vacuum insulation failure, magnet quenching, material defect, mechanical fatigue, external impact, electrical joint failure, etc., the protective devices and key...
The HL-LHC IT String, a test facility for the major components of the HL-LHC Inner Triplet, is currently in its construction and commissioning phases in a surface building at CERN. The primary motivation of the HL-LHC IT String is to study and validate the collective behavior of its different subsystems which include mainly: the inner triplet superconducting magnets and their correctors, a...
Abstract
Vacuum insulation is commonly used in cryogenic liquid storage, in the ground applications, because of its excellent insulation performance. However, the accidental loss of insulating vacuum might result in significant boil-off of the stored liquid. The loss of the stored liquid through boil-off not only impacts energy efficiency but also poses a serious safety concern. The hazards...
