PHOTON: A program for synchrotron radiation dose calculations

Description: A computer program, PHOTON, has been developed to calculate radiation levels associated with a general synchrotron beamline arrangement. PHOTON calculates the transmitted an scattered spectra as the synchrotron beam passes through sequential filters. The Compton component of this scattered radiation can then be passed through a series of materials composing a shielding wall. This radiation can then be used to calculate a dose in a medium outside of the shielding wall. Program input is such that… more

Test results from 1. 8-m SSC (Superconducting Super Collider) model dipoles

Description: We report results from the first four in a series of 1.8 m-long dipoles built as part of the Superconducting Super Collider (SSC) R and D program. Except for length, these models have the features of the SSC design, which is based on a two-layer costheta coil with 4 cm aperture. As compared to 17 m, the SSC design length, these 1.8 m magnets are a faster and more economical way of testing changes in field shape, the ratio of copper to superconductor, cable support at the coil center and ends, a… more

Cable-in-conduit conductor optimization for fusion magnet applications

Description: Careful design of the toroidal-field (TF) and poloidal-field (PF) coils in a tokamak machine using cable-in-conduit conductors (CICC) can result in quite high overall winding-pack current densities - even with the high nuclear heat loads that may be imposed in operating a fusion reactor - and thereby help reduce the overall machine size. In our design process, we systematically examined the operational environment of a magnet, e.g., mechanical stresses, current, field, heat load, coolant temper… more

High performance inboard shield design for the compact TIBER-II test reactor: Appendix A-2

Description: The compactness of the TIBER-II reactor has placed a premium on the design of a high performance inboard shield to protect the inner legs of the toroidal field (TF) coils. The available space for shield is constrained to 48 cm and the use of tungsten is mandatory to protect the magnet against the 1.53 MW/m/sup 2/ neutron wall loading. The primary requirement for the shield is to limit the fast neutron fluence to 10/sup 19/ n/cm/sup 2/. In an optimization study, the performance of various candid… more

Correction of the field in the SSC dipoles using superconductor on the wedges

Description: The SSC colliding beam storage ring requires superconducting magnets capable of producing a magnetic field of 6.6 T which has very high accuracy. For many of the multipoles, that multipole must be reduced (at a radius of 1 centimeter) to the order of 0.2 parts in 10,000. This field accuracy is dictated by the physics of storing very small high-current proton beams at energies ranging from 1 TeV to 20 TeV. Magnetization of the superconductor can cause sextupole field errors of up to 6 parts in 1… more
