Vibrational, thermal, and alignment considerations of the laser system for Baseball II-T

Designing the Baseball II-T laser system required addressing a number of mechanical parameters. Among them are low frequency floor vibrations, high acoustical noise levels, and large thermal fluctuations in the vicinity of the experiment. In addition, the 8-in. apertures from the 300-K environment of the laser system had to be compatible with the cryogenic environment of the superconducting Baseball magnet. This paper discusses these problems and describes their influence on the laser system design. (auth)
