为适应不同测量系统的需要，对基座长度较小(4~6 mm)的平面薄膜DC-SQUID梯度仪进行了优化。这些平面DC-SQUID梯度仪在非屏蔽环境中的场梯度噪声优于5pT/cm/SPL Radic/(Hz)(在1 Hz，77K)。讨论了这些系统的其他组件，如电子设备、低温恒温器、扫描设备和数据分析软件。作为大学和对超导应用感兴趣的小公司开始合作的例子，展示了用于无损评估的工业系统和用于心肌梗死的床边调查的临床系统。
Planar thin film DC-SQUID gradiometers with small base length (4...6 mm) were optimized for application in different measurement systems. The field gradient noise of these planar DC-SQUID gradiometers in unshielded environment is better than 5 pT/cm/spl radic/(Hz) (at 1 Hz, 77 K). Other components of these systems like electronics, cryostats, scanning equipment, and data analysis software are discussed. An industrial system for nondestructive evaluation and a clinical system for bedside investigations on cardiac infarction are demonstrated as examples of starting cooperation between university and small companies interested in application of superconductivity.
