[222 E. Main Street, South Corner]
Photograph of the front and east side of a single-story, side-gabled stone building, viewed from the street and partially obscured by utility poles and potted trees on the sidewalk. An entrance is near the right side of the building, with several steps in front; a second entrance is partially visible behind a bay window near the left side of the image. A bench and a trash can are on the sidewalk outside the building, near the left side of the image, and a fire hydrant is visible at the curb near the center. At the right side of the image, there is a driveway and an extended wooden roof.

240-kA switch with potential application in electromagnetic-launch systems
Electromagnetic (EM) launchers have severe switching requirements. Switching demands for railgun systems, for instance, inlcude current conduction from hundreds of kA to a few MA, conduction times of a ms to a few s, standoff voltages as high as a few tens of kV, to rcovery voltages of 1 to 10 kV after conduction, opening and closing duty, and repetitive operation up to about 50 Hz. These demands, particularly for repetitive opening duty, are far beyond the capability of most current switches and switching concepts. This paper will review the performance of rod array triggered vacuum gap (RATVG) switches and discuss their potential for solving switching problems in EM launcher systems. A new mode of operation for the RATVG switch is proposed. Fundamental considerations for the operation of opening switches and their associated transfer circuits are presented. Methods of recovering the railgun's inductive energy to enable efficient repetitive operation are discussed and new circuits with such capability are proposed.

344 cm x 86 cm low mass vacuum window
The LBL Heavy Ion Spectrometer System (HISS) superconducting magnet contains a 1 m x 3.45 m x 2 m vacuum tank in its gap. A full aperture thin window was needed to minimize background as the products of nuclear collisions move from upstream targets to downstream detectors. Six windows were built and tested in the development process. The final window's unsupported area is 3m/sup 2/ with a 25 cm inward deflection. The design consists of a .11 mm Nylon/aluminum/polypropylene laminate as a gas seal and .55 mm woven aramid fiber for strength. Total mass is 80 milligrams per cm/sup 2/. Development depended heavily on past experience and testing. Safety considerations are discussed.

650 mm long liquid hydrogen target for use in a high intensity electron beam
This paper describes a 650 mm long liquid hydrogen target constructed for use in the high intensity electron beam at the Stanford Linear Accelerator Center. The main design problem was to construct a target that would permit the heat deposited by the electron beam to be removed rapidly without boiling the hydrogen so as to maintain constant target density for optimum data taking. Design requirements, construction details and operating experience are discussed.
