Stacks of superconducting tape can be used as composite bulk superconductors for both trapped field magnets and for magnetic levitation. Little previous work has been done on quantifying the levitation force behavior between stacks of tape and permanent magnets. This paper reports the axial levitation force properties of superconducting tape wound into pancake coils to act as a composite bulk c...

We have integrated a system of 16 RISC CPUs to help reconstruct and analyze a 1.3 Terabyte data set of 400 million high energy physics interactions. These new CPUs provided an affordable means of processing a very large data set. The data was generated using a hadron beam and a fixed target at Fermilab Experiment 769. Signals were recorded on tape from particles created in or decaying near the ...

21M.380 12/3/09 Turbo-Sonic Whopper The Turbo-Sonic Whopper (TSW) is an instrument which has been designed in the spirit of technology based musical creation. With a majority of its parts being constructed from found materials, the TSW is truly a piece of experimental music technology. The inspiration for the TSW comes from Nicholas Collins’ book Handmade Electronic Music as well as from variou...

The mechanics of the "tape" over a flat-head is investigated. It has been recently shown that a thin, flexible tape, traveling over a flat recording head under tension contacts the head over the central area of the head. This phenomenon is due to the selfacting, subambient foil bearing effect. In this paper, as a first order of approximation, a simplified system is analyzed; where a uniform sub...

Tape storage drives use lithographically deposited anisotropic magnetoresistive (AMR) sensors to read magnetic transitions written on tape. The read-back signal and the reliability of an AMR sensor are both affected by sensor temperature. Because current passes through the sensor, it is subject to joule heating, dependent on both the geometry of the sensor and the thermal conductivities of its ...

Tape casting technics were used to realize a screen with continuous change in characteristics. Different hexaferrite compositions owned by the Ba3C02-~Zn~Fe24041 (Z) family were synthetized by coprecipitation method and calcined at 1200 "C in air. Then a slurry containing this powder is slip casted using tape casting. The tapes are dried under magnetic fied in order to orient the magnetic plate...
