Thermal design and analysis of superconductors for the toroidal field coils of TNS. [NbTi]

Description: The toroidal field coils in two of the four TNS field coil design options are superconducting. NbTi superconductors are used in the low field design option and Nb/sub 3/Sn superconductors are used in the high field design option. The preliminary conceptual design parameters of the coils and the superconductors have been developed. The selected coil shape is the pure tension D-configuration. The superconductors are the multifilamentary, cabled design and are cooled by forced flow supercritical h… more

Analytical studies of advanced high-field designs: 20-tesla large-bore superconducting magnets

Description: Several emerging technologies have been combined in a conceptual design study demonstrating the feasibility of producing ultrahigh magnetic fields from large-bore superconducting solenoid magnets. Several designs have been produced that approach peak fields of 20-T in 2.0-m diameter inner bores. The analytical expressions comprising the main features of CONDUCTOR and ADVMAGNET, the two computer programs used in the design of these advanced magnets, are also discussed. These magnets and design t… more

Performance of the MFTF magnet cryogenic power leads

Description: The cryogenic power lead system for the MFTF superconducting magnets has been acceptance tested and operated with the magnets. This system, which includes 5-m-long superconducting buses, 1.5-m-long vapor-cooled transition leads, external warm buses, and a cryostack, can conduct up to 6000 A (dc) and operate adiabatically for long periods. We present both design details and performance data; our MFTF version is an example of a reliable lead system for large superconducting magnets contained in a… more

A 5-cm dipole for the SSC-DE-1

Description: A 5cm SSC superconducting dipole that develops 6.6 tesla at 5790 A is proposed. The two layer magnet has 12% more transfer function than the present design as a result of using thin collars and close in'' iron. The thin collars provide precise positioning of the coils; they also provide minimum prestress (perhaps 2000 psi) as aid for magnet assembly. A welded skin around the iron provides the final prestress and shapes and the coil geometry. A prestressed aluminum bar placed between the vertica… more

DC CICC retrofit magnet. Quarterly progress report, July 1992

Description: The coil system presented here for the MHD retrofit magnet incorporates many features of the latest in superconducting magnet technology and finite element modeling to create an efficient and viable design concept. At the core of the design is the niobium titanium (NbTi) superconducting Cable-in-Conduit Conductor (CICC). Engineered to create moderately high magnetic fields (up to 8 T) with essentially no power loss, this specific CICC design provides good load carrying capacity, operating margi… more

The HILDA program

Description: Although this report is called a program document, it is not simply a user`s guide to running HILDA nor is it a programmer`s guide to maintaining and updating HILDA. It is a guide to HILDA as a program and as a model for designing and costing a heavy ion fusion (HIF) driver. HILDA represents the work and ideas of many people; as does the model upon which it is based. The project was initiated by Denis Keefe, the leader of the LBL HIFAR project. He suggested the name HILDA, which is an acronym f… more

Analysis of Voltage Signals from Superconducting Accelerator Magnets

Description: We present two techniques used in the analysis of voltage tap data collected during recent tests of superconducting magnets developed by the Superconducting Magnet Program at Lawrence Berkeley National Laboratory. The first technique was used on a quadrupole to provide information about quench origins that could not be obtained using the time-of-flight method. The second technique illustrates the use of data from transient flux imbalances occurring during magnet ramping to diagnose changes in t… more

Toroidal magnetic detector for high resolution measurement of muon momenta

Description: A muon detector system including central and end air-core superconducting toroids and muon detectors enclosing a central calorimeter/detector are described in this paper. Muon detectors are positioned outside of toroids and all muon trajectory measurements are made in a nonmagnetic environment. Internal support for each magnet structure is provided by sheets, located at frequent and regularly spaced azimuthal planes, which interconnect the structural walls of the toroidal magnets. In a preferre… more

D0 Solenoid Upgrade Project: Thermal Contraction Analysis for the D0 Solenoid Chimney

Description: This engineering note documents the thermal contraction analysis that was done for the D-Zero solenoid chimney. The analysis was done as support of the 'Design Report of the 2 Tesla Superconducting Solenoid for the Fermilab DO Detector upgrade.' The cryogenic LHE and LN2 lines were analyzed for combined pressure, thermal movement, and dead weight. The tubing was stress analyzed per ASME code for Pressure Piping, standard ANSI AS:ME B31.3, for eight combinations ofthermal loading. A commercial p… more

Consecutive quenches and the safety leads

Description: The safety leads of the Energy Saver were designed to handle occasional quenches. In order to save capital investment in another system of plumbing they involve no gas cooling. In their design optimization was sought on the ratio of load capability (for a single quench) to steady state heat leak into the liquid helium environment. Reference 1 describes the design considerations and tests on a prototype made out of constanta. The actual production models are made out of 304 Stainless Steel rods … more

Engineering Parameters for Four Ignition TNS Tokamak Reactor Systems

Description: The ORNL/Westinghouse program for The Next Step (TNS) tokamak beyond TFTR has examined a large number of potential configurations for D-T burning ignition tokamak systems. An objective of this work has been to quantify the trade-offs associated with the assumption of certain plasma physics criteria and toroidal field coil technologies. Four tokamak system point designs are described, each representative of the TF coil technologies considered, to illustrate the engineering features associated wi… more

A Technique for Epoxy Free Winding and Assembly of COS θ Coils for Accelerator Magnets

Description: Traditional methods of magnet construction (wet winding) use molded coil subassemblies bonded together with epoxy impregnated fiberglass tape. This is a highly labor intensive process involving redundant operations for each of the four coils. The epoxy free winding technique (dry winding) eliminates the epoxy curing steps and also allows all four coils to be wound on 3 common winding mandrel, thereby reducing winding stations and handling. The tooling required for dry winding is a radical depar… more
