The Accelerator System String Test (ASST) was a congressionally mandated milestone for the Superconducting Super Collider Laboratory (SSCL) to demonstrate powered operation of a half-cell of industrially-fabricated collider magnets before mass production ...

The ASST magnet string cryogenic refrigeration requirements were planned around an original design and a much smaller, backup, He refrigeration system. The ASST schedule required that the backup, or Plan B, helium refrigerator provide and meet all the req...

The Accelerator System String Test (ASST) was a congressionally mandated milestone for the Superconducting Super Collider Laboratory (SSCL) to demonstrate powered operation of a half-cell of industrially-fabricated collider magnets before mass production could begin. In this paper I describe the installation of the ...

The Accelerator Systems String Test (ASST) R&D Testing Facility has been established at the SSC Laboratory to test Collider and High Energy Booster (HEB) superconducting magnet strings. The facility is operational and has had two testing periods utilizing...

The Accelerator Systems String Test (ASST) R&D Testing Facility has been established at the SSC Laboratory to test Collider and High Energy Booster (HEB) superconducting magnet strings. The facility is operational and has had two testing periods utilizing a half cell of collider prototypical magnets with the ...

A prototype Superconducting Super Collider (SSC) 50 mm dipole magnet cryostat, DCA323, was instrumented at Fermilab and delivered to the SSC Laboratory for installation into the accelerator systems string test facility. In series with other magnets, the i...

= "hello"; Strings are immutable. � You can assign a different String object to a String variable, but you character of a string is at position 0. Immutable Strings String s1 = "hello"; String s2 = s1; s1 = "jello"; ...

An expander driven by waste heat fluid is operatively connected to a synchronous or induction generator. A brake/clutch controller selectively connects the power recovery string to an eddy current brake/flywheel in order to maintain line frequency and control speed during normal conditions and to minimize acceleration of the string ...

In this paper we describe the operation and testing of a string of magnets comprising a full cell of the Superconducting Super Collider (SSC). The full cell configuration composed of ten dipoles, two quadrupoles, and three spool pieces is the longest SSC magnet string ever tested. Although the tests of the full cell were undertaken after the SSC project ...

It seems likely that string theory has a landscape of vacua that includes very many metastable de Sitter spaces. However, as emphasized by Banks, Dine, and Gorbatov, no current framework exists for examining these metastable vacua in string theory. In this paper we attempt to correct this situation by introducing an eternally inflating background in which ...

This item is an annotated homework problem relating to Newton's Second Law for introductory physics students. The author explains the steps needed to find string tension in a pulley system when given distance, mass, and angle of incline. Free body diagrams and additional sequential explanations are then provided to find the ...

A portable, high speed, computer-based data logging system for field testing systems or components located some distance apart employs a plurality of spaced mass spectrometers and is particularly adapted for monitoring the vacuum integrity of a long string of a superconducting magnets such as used in high energy particle ...

Grand Unified Theories predict the existence of topological structures in the early universe. Some of the properties and consequences of having such topological structures in the early universe are examined here. The statistical properties of the system of strings produced at a phase transition in the early universe are studied using a Monte Carlo ...

... Setting up a cyclic matrix with this vector-string, one can describe the periodic system-signal by cyclic convolution of reticle-string and image-string. ...

Three similar helium refrigerator systems have been installed at the Superconducting Super Collider Laboratory (SSCL) N15 site; the ASST-A system, which will be used for the accelerator system's full cell string test; the N15-B system, which will be used ...
