Development of a Pulsed Cable Test Facility for superconducting ohmic heating coils

Induction heating of aluminium billets using superconducting coils

It is proposed to apply high-temperature superconducting (HTS) tape in the coil windings for induction heaters for aluminium or copper extrusion billets. The potential for efficiency improvements is substantial, as conventional copper coil induction heaters rated for up to around 1 MW operate with an overall efficiency of typically only 50–60%. The efficiency of a HTS induction heater depends v...

Radiation Shielding for Superconducting RF Cavity Test Facility at A0

The results of Monte Carlo radiation shielding study performed with the MARS15 code for the vertical test facility at the A0 north cave enclosure at Fermilab are presented and discussed.

Quantification of metal release from stainless steel electrodes during conventional and pulsed ohmic heating

Asymptotic stability for a symmetric parabolic problem modeling Ohmic heating

We consider the asymptotic behavior of the solution of the non-local parabolic equation ut = (κ (u))rr + (κ (u))r r + f (u) (a+2πb ∫ 1 0 f (u)r dr) 2 , for 0 < r < 1, t > 0, with a homogeneous Dirichlet boundary condition. The equation is the so-called Ohmic-heating model, which comes from thermal electricity in this paper, u and f (u) represent the temperature of the conductor and the electric...

Experience with Superconducting Cavity Operation in the Tesla Test Facility

A description of the TESLA Test Facility, which has been set up at DESY by the TESLA Collaboration, will be given. Measurements of the superconducting 9-cell cavities in vertical and horizontal test cryostats will be presented, as well as the experience with the first two accelerator modules in the TTF linac. Future cavity R&D efforts will be described.
