Hydrogen - Dr. Jekyll and Mr. Hyde: A Motivation for the Hydrogen Workshop at Jefferson Lab

摘要

As shown by both its history and its present scientific and technological roles, hydrogen presents not only opportunities but distinct challenges. The opportunities, which once included aeronautics, now encompass semiconductors and electronics/opto-electronics in general. Transportation has returned along with the grand prospect of a "hydrogen economy" based on more recent advances in the technologies of H generation and use. Challenges presented by H have grown acute for accelerator builders, especially in the areas of superconducting accelerating structures, large vacuum systems, and cryogenic systems.
