RF and Surface Properties of Superconducting Samples [PDF]

open access: yes, 2011
The surface resistance Rs of superconducting cavities can be obtained from the unloaded quality factor Q0. Since Rs varies strongly over the cavity surface its value must be interpreted as averaged over the whole cavity surface.

Thermal quadrupole method with internal heat sources [PDF]

open access: yes, 2012
A new method based on the thermal quadrupoles technique for heat transfer modelling in multilayered slabs with heat sources is proposed. Classical thermal quadrupoles use hyperbolic functions and numerical problems occur according to the argument value ...
