-Superconducting transmission line magnet test system for an injector accelerator of a staged VLHC proton-proton colliding beam accelerator has been built and operated at Fermilab. The 1.5 m long, twin-aperture, combined function dipole magnet of 2 Tesla field is excited by a single turn 100 kA transmission line superconductor. The 100 kA dc current is generated using dc-dc switching converters powered by a bulk 240 kW supply. A pair of horizontally placed conventional leads facilitates transfer of this current to the magnet transmission line superconductor operating at liquid helium temperature. Fabrication of magnet components and magnet assembly work are described. The magnet test system and its operation are presented, and the performance is summarized.

“…With the AISI 1008, 1mm thick laminated steel for the VLHC Stage 1 magnet, the deviation at 90 kA current (also 2 T field) was about 40%. With the help of correction holes in the magnet poles, however, a very highquality magnetic field was achieved [6]. Based on this experience we expect that with some effort an even higher accelerator quality B-field can be achieved with the proposed window frame magnetic design for the fast cycling magnet.…”

Abstract-Recently proposed synchrotrons, SF-SPS at CERN and DSF-MR at Fermilab, would operate with a 0.5 Hz cycle (or 2 second time period) while accelerating protons to 480 GeV. We examine possibilities of superconducting magnet technology that would allow for an accelerator quality magnetic field sweep of 2 T/s. For superconducting magnets the cryogenic cooling power demand due to AC losses in the superconductor leads to a high operational cost. We outline a novel magnet technology based on HTS superconductors that may allow to reduce AC losses in the magnet coil possibly up to an order of magnitude as compared to similar applications based on LTS type superconductors.

“…The concept of transmission line superconducting accelerator magnets was first developed for the VLHC Stage 1 accelerator [13], and a short prototype of the VLHC-LF magnet was successfully built and tested [14,15]. This magnet has been also proposed recently for the Low Energy Ring [16] at the LHC.…”

Dual fast-cycling superconducting synchrotron at Fermilab and a possible path to the future of high energy particle physics

J. Inst.

We briefly outline shorter and longer term physics motivation for constructing a dual, fast-cycling superconducting synchrotron accelerator (DSFMR -Dual Super-Ferric Main Ring) in the Tevatron tunnel at Fermilab. We discuss using this accelerator as a high-intensity dual neutrino beam source for the long-baseline neutrino oscillation search experiments, and also as a fast, dual pre-injector accelerator for the VLHC (Very Large Hadron Collider).During the past decade developments in the neutrino physics combined with progress in the cosmological models of dark matter and dark energy suggest that neutrinos play a fundamental role in our universe. It has been determined through solar, atmospheric, reactor and accelerator experiments that neutrinos change flavor (oscillate) while passing through matter. This implies that at least two neutrino species have a non-zero mass [1], thus being in a striking contradiction to the Standard Model (SM), and therefore suggesting existence of the physics Beyond the Standard Model (BSM). In addition, the possibility of neutrinos having a small mass may provide a bridge (via e.g. a see-saw mechanism) to the GUT (Grand Unified Theory -physics models where at energies above 10 14 GeV the electromagnetic, weak nuclear and strong nuclear forces are fused into a single field) theories including the origin of mass in the universe. As a consequence of this new situation a need for the resolution to the neutrino physics has risen to a level that is not just complimentary to other high-energy particle physics programs but turns out to be absolutely necessary to further understanding of the microscopic structure and workings of the universe.In neutrino physics phenomenology neutrinos with physical flavors, ν α (α = e, µ, τ), are assumed to be linear super-positions, through a unitarity matrix, of neutrino fields with definitive masses ν i (i = 1, 2, 3). A common parameterization for this matrix uses mixing angles,
