Walaupun penyepaduan skala yang lebih besar meningkatkan kepraktisan litar Josephson superkonduktor, beberapa masalah teknikal mula timbul semasa kemajuannya. Salah satu masalah ialah pertambahan arus melalui satah tanah (ground current). Arus tanah yang berlebihan menghasilkan medan magnet tambahan dan mengurangkan margin operasi litar, kerana peranti Josephson superkonduktor sangat sensitif kepada medan magnet. Dalam kertas ini, kami menilai taburan semasa dalam satah tanah superkonduktor melalui kedua-dua eksperimen dan pengiraan berangka. Kami juga mengesahkan dua kaedah untuk menekan arus tanah. Satu ialah struktur slot dalam satah tanah, dan satu lagi ialah penjajaran titik pengekstrakan semasa. Penindasan arus tanah dinilai secara kuantitatif.

Abstract: Although larger scale integration enhances the practicability of superconducting Josephson circuits, several technical problems begin to emerge during its progress. One of the problems is the increase of current through a ground plane (ground current). Excess ground current produces additional magnetic field and reduces operation margins of the circuits, because superconducting Josephson devices are very sensitive to magnetic field. In this paper, we evaluate current distribution in a superconducting ground plane by means of both experiments and numerical calculation. We also verify two methods for suppressing the ground current. One is a slot structure in the ground plane, and the other is alignment of the current-extraction point. Suppression of the ground current is quantitatively evaluated.
