Development of a high-speed Solenoid valve: investigation of Solenoids
IEEE Transactions on Industrial Electronics, 1995Co-Authors: T. Kajima, Y. KawamuraAbstract:The authors have developed a high-speed Solenoid valve with a 1 ms switching time to control diesel engines electronically. In this paper, the authors focused their attention on developing the Solenoid itself, investigating methods to be used for the fast operation of the Solenoid valve. First, by using a mathematical model, they quantitatively examined the effects of design particulars, such as the dimensions of the Solenoids and the number of turns of coil, on the switching time. According to the results obtained by the above examinations, they studied an effective method for fast switching. Next, they investigated appropriate and comprehensive methods that would satisfy given specifications under the various restrictions inherent in the Solenoid valve's operation. In the final stage, they manufactured Solenoid valves in accordance with the investigated methods, and evaluated their performance. >

Generalized plane strain analysis of superconducting Solenoids
Journal of Applied Physics, 1999Co-Authors: W. Denis Markiewicz, M.r. Vaghar, Iain R. Dixon, Hamid GarmestaniAbstract:A stress analysis of superconducting Solenoids is presented which includes a generalized plane strain (GPS) condition for the axial strain. The GPS condition is introduced on the assumption that the deformation of a Solenoid from a right circular cylinder is small. The GPS assumption results in an analytic solution for all three components of stress and strain in a Solenoid. The work is presented in the context of the historical development of stress analysis for Solenoids. The general stress equations for a magnetic Solenoid are formulated. The relationship between a right cylinder deformation and the generalized plane strain condition is examined for the physical conditions in the central region of a Solenoid magnet. The general analytic solutions of the stress equations are given for the cases of magnetic and thermal loading. The constant coefficients are determined for cases of common interest in Solenoid magnet design. The analytic results are compared with numerical analysis results for an example s...

Progress on the MICE Tracker Solenoids
IEEE Transactions on Applied Superconductivity, 2008Co-Authors: Michael A. Green, Steve VirostekAbstract:The first magnets for the muon ionization cooling experiment will be the tracker Solenoids that form the ends of the MICE cooling channel. The primary purpose of the tracker Solenoids is to provide a uniform 4 T field (to better than plusmn0.3 percent over a volume that is 1 meter long and 0.3 meters in diameter) spectrometer magnet field for the scintillating fiber detectors that are used to analyse the muons in the channel before and after ionization cooling. A secondary purpose for the tracker magnet is the matching of the muon beam between the rest of the MICE cooling channel and the uniform field spectrometer magnet. The tracker Solenoid is powered by three 300 amp power supplies. Additional tuning of the spectrometer is provided by a pair of 50 amp power supplies across the spectrometer magnet end coils. The tracker magnet will be cooled using a pair of 4 K pulse tube coolers that each provide 1.5 W of cooling at 4.2 K. Final design and construction of the tracker Solenoids began during the summer of 2006. This report describes the progress made on the construction of the tracker Solenoids.

Design parameters for gas-cooled electrical leads of the g-2 magnets
Cryogenics, 2005Co-Authors: L. X. Jia, L.j. Addessi, J. R. Cullen, A. J. Esper, R. E. Meier, C. Pai, Louis Snydstrup, Michael A. GreenAbstract:This report presents the design parameters for a pair of 5300 A gas-cooled electrical leads for the g-2 Solenoids and a pair of 2850 A leads for the inflector magnet. The lead design parameters are derived from a scale analysis of two one-dimensional, thermo-fluid-electro-quasi-coupled, and non-linear differential equations. The analysis may apply to general gas-cooled electrical lead design. As an illustration, these design parameters are applied to multi-tube gas-cooled leads that are proposed for the g-2 Solenoid magnet system. Multiple electrical current carrying tubes and multiple gas flow cooling channels will increase the lead current capacity and lead efficiency for enhanced heat transfer and low flow pressure drop.

Bent Solenoid simulations for the muon cooling experiment
Advances in cryogenic engineering, 1999Co-Authors: Michael A. Green, Y.m. Eyssa, S. Kenney, J.r. Miller, S. PrestemonAbstract:The muon collider captures pions using Solenoidal fields. The pion are converted to muons as they are bunched in an RF phase rotation system. Solenoids are used to focus the muons as their emitance is reduced during cooling. Bent Solenoids are used to sort muons by momentum. This report describes a bent Solenoid system that is part of a proposed muon cooling experiment. The superconducting Solenoid described in this report consists of a straight Solenoid that is 1.8 m long, a bent Solenoid that is 1.0 m to 1.3 m long and a second straight Solenoid that is 2.6 m long. The bent Solenoid bends the muons over an angle of 57.3 degrees (1 radian). The bent Solenoid has a minor coil radius (to the center of the coil) that is 0.24 m and a major radius (of the Solenoid axis) of 1.0 m. The central induction along the axis is 3.0 T There is a dipole that generates an induction of 0.51 T, perpendicular to the plane of the bend, when the induction on the bent Solenoid axis is 3.0 T.

The use of superconducting Solenoids in a muon collider
IEEE Transactions on Appiled Superconductivity, 1999Co-Authors: Michael A. Green, Y.m. Eyssa, J.r. Miller, Robert B. Palmer, Robert WeggelAbstract:Superconducting Solenoids are integral part of the proposed muon collider and Higgs factory. Superconducting Solenoids that produce inductions up to 15 T will be used to capture pions that are produced by a proton beam impinging on a target contained within the Solenoid. After the pions are captured they are phase rotated and allowed to decay to muons. The phase rotation and pion decay channel keeps the pions and muons captured in a 1.25 T rotation system. Superconducting Solenoids will also be integral part of the muon cooling system. Within the muon cooling channel, which is projected to be up to 300 meters long, Solenoidal fields up to 30 T are needed. This report presents the latest thoughts on how superconducting Solenoids will be used as part of the muon collider.
