Production and use of high-grade silicon-diode temperature sensors

Description: With todays tight budgets and increasing costs, helium refrigeration system engineers must design for increased cycle efficiency and shave the refrigerators excess capacity to reduce capital costs and operating expenses. For a project such as ISABELLE this task is noteworthy since the load is not one easily calculable dewar but 1100 magnets supplied by long transfer lines, inteconnecting links and multitudes of lead pots. Realizing the consequences, ISA's cryogenic group has been measuring heat… more

High energy hadron colliders

Description: The more novel and important design considerations and features of high energy hadron colliders (pp or p anti p) are discussed. The paper does not attempt to be sufficient for making a complete design, but contains enough references to other papers necessary for doing so. Formulas are generally given without derivation, and notations are not consistent from section to section. For most formulas the derivation is transparent although the mathematics may be lengthy. Whenever obscure, an explanati… more

Upgraded coil configuration for ISABELLE magnets

Description: Achievement of the design field of 5 T in the ISABELLE dipole magnets is turning out to be more arduous than expected and several avenues of improvement are being pursued. One possibility for improving training and peak field performance is discussed in this paper. It has been recognized that the inert spacers with their adjacent active turns in the cosine magnet windings can be replaced by a double thickness braid operating at approximately half-current density in 46 of the 190 turns. Since th… more

Optimization of compact synchrotron optics for x-ray lithography

Description: The production of integrated circuits having sub-micron component dimensions has motivated the development of compact electron storage rings to provide synchrotron x-ray radiation. This paper presents considerations for optimizing the optics for small radius rings using superconducting dipole magnets. The key parameters are the sizes and angular divergences of the source points illuminating the different ports. Two ring designs are compared in terms of theoretical beam parameters achievable usi… more

Transient response of a thermal buffer: a study for ISABELLE

Description: Operation of the superconducting magnets in ISABELLE may necessitate rapid cooldown and warmup from ambient (300K) to liquid helium temperature (3K) to meet the requirements of the experimental program. Similarly, unprogrammed temperature excursions can also occur due to operator error or equipment malfunction. The coal bore tube of the magnets has a small mass relative to the more massive iron laminations and the stainless steel support tube. In addition the magnet coil, in thermal contact wit… more
