Abstract

Two types of first-order gradiometers equipped with 50 mm diameter pickup coils were made out of an REBaCuO High-T_c superconducting (HTS) flexible tape. The HTS tapes were formed into the HTS gradiometers by ``cut-and-wind'' method without cable jointing.

The HTS gradiometers were examined at 77 K for magnetic sensitivity to a gradient field applied by an external coil. The axial-type HTS gradiometer eliminated the magnetic field output of the device induced by a uniform field, and enhanced the magnetic field output induced by a gradient field on the axis of the pickup coil. The planar-type HTS gradiometer made it possible to detect a 20 mm diameter steel cylinder placed beside the pickup coil in a uniform field of 100 µT by detecting the spatial field gradient in the vicinity of a ferromagnetic object.

使用一阶梯度仪测量梯度磁场，梯度仪配备直径 50 毫米的拾取线圈，线圈由 2G 高锝超导带制成

用 REBaCuO 高锝超导（HTS）柔性带制作了两种配备 50 毫米直径拾波线圈的一阶梯度仪。HTS 梯度仪在 77 K 下进行了检测，以确定其对外部线圈施加的梯度场的磁灵敏度。轴向型 HTS 梯度仪消除了由均匀磁场引起的设备磁场输出，增强了由拾取线圈轴上的梯度磁场引起的磁场输出。平面型 HTS 梯度仪通过检测铁磁性物体附近的空间场梯度，可以在 100 µT 的均匀磁场中检测放置在拾取线圈旁边的直径为 20 毫米的钢筒。

期刊介绍： Physica C (Superconductivity and its Applications) publishes peer-reviewed papers on novel developments in the field of superconductivity. Topics include discovery of new superconducting materials and elucidation of their mechanisms, physics of vortex matter, enhancement of critical properties of superconductors, identification of novel properties and processing methods that improve their performance and promote new routes to applications of superconductivity. The main goal of the journal is to publish: 1. Papers that substantially increase the understanding of the fundamental aspects and mechanisms of superconductivity and vortex matter through theoretical and experimental methods. 2. Papers that report on novel physical properties and processing of materials that substantially enhance their critical performance. 3. Papers that promote new or improved routes to applications of superconductivity and/or superconducting materials, and proof-of-concept novel proto-type superconducting devices. The editors of the journal will select papers that are well written and based on thorough research that provide truly novel insights.
