Arrangement for generating electrical impulses on superconductor loops

The invention relates to an arrangement for generating. ^ Ting of electrical pulses on superconductor loops, preferably for measuring arrangements for navigation purposes in aircraft and space vehicles, whereby the position and the change in position are determined using the Sagnac effect willo

So far, such arrangements are not known for the purposes mentioned become.

The object of the invention is to provide a way of electrical or to generate electromagnetic pulses on a superconductor loop and thereby run time measurements of electrical pulses that are propagate on a superconductor at approximately the speed of light, to be able to carry out, ^ this object is achieved by the invention in that in a superconductor loop of preferably type II superconductor an intermediate piece of preferably type I superconductor is installed, its with Ends provided with insulation layers, on the one hand, carry signal input layers and, on the other hand, current take-off layers, which are provided by a signal transmitter are controlled and an auxiliary coil is arranged to generate a normally conductive state within an intermediate region.

Quartz It is further proposed that the intermediate _{piece consists of a lead or tin layer vapor-deposited on z e} B _e /, into which the ends of the superconductor loop are vapor-deposited and the signal input layers as well as the current collection layers on the intermediate piece are isolated from the intermediate piece by vapor-deposited insulator layers, are vaporized.

Furthermore, the invention further provides that the signal generator also provides the control pulses for the magnetic field EL of the auxiliary coil and the current collection layers are connected to a measuring device ₀

The invention is described below and show the drawing

FIG _e 2 is a timing diagram of pulses input gear.

For the erfinduncscemäfte arrangement is suitable _e for signal generation are the Zvischenstüclc 20 by insulator layers 21,22,23, for example a vapor-deposited on quartz lead or tin layer, into which the ends of the superconducting loop are preferably evaporated 10 and the electric contact is produced 24 isolated, two parallel input layers 30, 31 lying parallel to the intermediate piece 20 A, which are connected to a signal transmitter 32. This signal generator 32 generates a current pulse I in the signal input layers 30, 31, which optionally also consist of a superconductor of type I or of type II. This current I generates magnetic fields H ₁ and H_. These in turn generate the super currents I. and I _, each of which is opposite to the magnetic fields H and H in such a way that the resulting magnetic field on the surface disappears within the London penetration depth. In this process, the requirement must be met that H. and H "smaller than the * critical field H of the type I superconductor adapter 20, or in the case of V _er "

Use of a type II or III superconductor spacer _{20 H 1 and JBL_}

are then advantageously smaller than H ₁ ", To avoid the interference of the two supercurrents I ₁ and I", an auxiliary coil 33 ψ in an area of the intermediate piece 20 generates a magnetic field H_ that is greater than H in a type I superconductor or is greater than H "in a Type II or III superconductor. Type III superconductors are understood to be those which show the “pinning effect”.

Through the field H ₁ . normal conduction is thus generated in the intermediate region 34, thus preventing the interference of the current pulses which are now processed on the superconductor as shown in FIG. At a sufficient distance of the current pulses from the intermediate section 20, the magnetic field H will now be - turned off to the current pulses I. and I ₂ to enable passage through the measuring section after circulation through the superconductor 10. The signal generator 32 also supplies the control pulses for the magnetic field H, .. To measure the arrival of the current pulses in the so-called measuring path '
