Can I read Ac-losses of superconducting Bi-2223 tapes with two different time constants on EtoBox?
Ac-losses of superconducting Bi-2223 tapes with two different time constants by Curt Schmidt; Ludovit Krempasky is a Engineering article available to read on EtoBox.
What is Ac-losses of superconducting Bi-2223 tapes with two different time constants about?
Ac-loss and time constant measurements were performed with Bi-2223 tape conductors in Ag matrix at 4.2 K and at 77 K. The frequency dependence of the loss curve shows the expected maximum at xs 1⁄4 1. In some cases the loss curve goes through a minimum in the higher frequency range and then increases again, with a possible second maximum. It is shown that this second increase is explained by eddy currents in the silver matrix, which are described by a second time constant # ( s. Both time constants, s and # can be seen in time constant measurements. The full theoretical description of time constant and loss measurements is given using a slab model. The agreement with the measurements is very good in parallel field orientation where the slab model is a good approach, and it is still a valuable approach in perpendicular field.
Who reads Ac-losses of superconducting Bi-2223 tapes with two different time constants?
