About the Book
"A superconductor is a material that can conduct electricity or transport electrons from one atom to another with no resistance. Superconductors are already used in many fields: electricity, medical applications, electronics and even trains. They are used in laboratories, especially in particle accelerators, in astrophysics with the use of bolometers, in ultrasensitive magnetic detectors called SQUIDs, and in superconducting coils to produce very strong magnetic fields. Heavily dopped semiconductor can become superconducting as Ge or Si. Nor the nobel metals (Cu,Ag,Au) neither the alcalins (Li, Na, K, Rb, Cs, Fr) present a superconducting phase transition at least above a few milikelvins. In general, good conductors are not good superconductors (meaning that they do not have high critical temperatures). The number of conducting electrons in a metal is of the order of 1022 per cm3. In a semiconductor at room temperature these are of the order of 1015 and in a heavily dopped semiconductor this number (in the same units) is around 1018. Superconductors are used in magnets that bend and focus the particle beam, as well as in detectors that separate the collision fragments in the target area. The magnets typically operate at high fields (around 5 tesla); the higher the operating fields, the higher the particle energies that can be achieved, and the smaller the size of the accelerator needed. Superconducting magnets are essential because they have low losses and enable higher magnetic fields; without them, power requirements and construction costs would be prohibitive. The low operating temperature of LTS magnets also helps to minimize scattering of the beam. The traditional use of superconductors has been in scientific research where high magnetic field electromagnets are required. The cost of keeping the superconductor cool are much smaller than the cost of operating normal electromagnets, which dissipate heat and have high power requirements. One such application of powerful electromagnets is in high energy physics where beams of protons and other particles are accelerated to almost light speeds and collided with each other so that more fundamental particles are produced.
Two-Volume ‘Brig’s Handbook of Methods & Research in Superconductors - Materials, Properties and Applications’ describes the fundamental electrical and structural properties of the superconductors as well as the methods researching those properties. Most of the material presented in this book is the result of authors’ own research that has been carried out over a long period of time.
Two-Volume ‘Brig’s Handbook of Methods & Research in Superconductors - Materials, Properties and Applications’ deals with both the experiment and the theory. Superconducting and normal-state properties are studied by several methods. The authors presented investigations of traditional and new materials. The superconducting order parameter symmetry is discussed and consequences of its actual non-conventional symmetry are studied. This handbook will certainly encourage further experimental and theoretical research in new theories and new superconducting materials. The handbook, covers the advanced techniques and concepts of superconductivity, is intended for a wide range of readers."
