Abstract:
Superconducting tunnel junctions (STJs) can be used as radiation detectors that combine the high energy resolution of cryogenic sensors with the high speed of nonthermal devices. STJ detectors were initially developed for x-ray astronomy and materials science and have more recently found applications in nuclear and particle physics. This tutorial describes the basic physics of STJ detectors and their operation as an introduction to the field.

01:28Types Of Superconductors
A superconductor is a substance that offers zero resistance to the electric current when it drops below a critical temperature. Zero resistance is not the only interesting phenomenon as materials reach their transition temperatures. A second effect is the exclusion of magnetic fields. This is known as the Meissner effect. A light, permanent magnet placed over a superconducting sample will levitate in a stable position above the superconductor. High-speed trains that levitate on strong...
01:24Superconductor
A substance that reaches superconductivity, a state in which magnetic fields cannot penetrate, and there is no electrical resistance, is referred to as a superconductor. In 1911, Heike Kamerlingh Onnes of Leiden University, a Dutch physicist, observed a relation between the temperature and the resistance of the element mercury. The mercury sample was then cooled in liquid helium to study the linear dependence of resistance on temperature. It was observed that, as the temperature decreased, the...
