摘要： A High Temperature Superconducting (HTS) Superconducting Quantum Interference Device and methods for fabrication can include at least one bi-Superconducting Quantum Interference Device. The bi-SQUID can include an HTS substrate that can be formed with a step edge. A superconducting loop of YBCO can be deposited on the step edge to establish two Josephson Junctions. A superconducting path that bi-sects the superconducting loop path can also be deposited onto the substrate. In some embodiments, the bisecting path can cross the step edge twice, and the bisecting path can be ion milled at one of the crossing points to round the bisecting path and thereby remove the fourth Josephson Junction at the other crossing point. In still other embodiments, the bisecting path can be completely on the upper shelf (or the lower shelf), and the bisecting path can be ion damaged, ion damaged, or particle damaged, to establish the third Josephson Junction.

摘要： The present invention introduces a method, device and a computer program for removing artifacts present in individual channels of a multichannel measurement device. At first, a basis is generated defining an n-dimensional subspace of the N-dimensional signal space, where n is smaller than N, where using in the definition of the n-dimensional basis a physical model of a Signal Space Separation method, or a statistical model based on the statistics of recorded N-dimensional signals. Thereafter, a combined (n+m)-dimensional basis is formed by adding m signal vectors to the n-dimensional basis, each of these m signal vectors representing a signal present only in a single channel of the N-channel device. After this the recorded N-dimensional signal vector is decomposed into n+m components in the combined basis, and finally, components corresponding to the m added vectors in the combined basis are subtracted from the recorded N-dimensional signal vector.

摘要： An RF DC SQUID based magnetometer capable of sensing coherent magnetic fields up to 200 MHz and higher is developed which overcomes frequency limitations associated with noise signals due to transmission line delays between the SQUID circuit and readout electronics. The bandwidth limitations are overcome by superimposing the RF flux on the modulation flux to produce at the SQUID output a binary phase modulated RF voltage, which is processed to lock the static flux, and to control modulation regime by producing an AC bias for the RF flux. RF readout electronics based on a double lock-in technique (sequential demodulation of the RF SQUID voltage at the modulation flux frequency ωm and the RF flux frequency ωRF), yields a signal proportional to the product of amplitude and phase cosine of RF flux with linear dynamic range up to five orders in magnitude if compared to DC SQUID operated in traditional flux-locked loop regime.
