0.4 V, voltage between source and drain -6 V, voltage between source and second gate -5.5 V. On changing the bias voltage on the first gate over the range 0.3 to 1.8 V the amplification coefficient of the fets changed, but this did not affect the level of the flicker noise of the transistors.

For EDS-type magnetically levitated trains, magnetic shielding of stray fields produced by superconducting magnets is an important task. We seek the optimal thickness distribution (configuration) of magnetic material, which is the lightest and keeps the magnetic field at tolerable levels in the vehi
A simple qualitative model is proposed to explain the fast initial change of the magnetic field of superconducting magnets which operate in the persistent mode. Using this model the additional component of the transport current which is induced by the decaying screening currents can be represented.
