Non-destructive Testing with a SQUID Magnetometer

Non-Destructive Testing

This book consists of a collection of 27 articles dealing with the subject of probabilistic engineering mechanics with special emphasis on the ensuing computational issues. The book has two parts. The first part is meant as a tutorial on the basic aspects of probabilistic mechanics, whereas the second part is an overview of some of the applications that rely on probabilistic concepts for their ...

Non-destructive Testing

This section contains a review of physical fundamentals and results of practical implementation of methods of nondestructive testing (NDT) and evaluation. It also presents relevant information on magnetic, electrical, eddy current, HF electromagnetic, infrared, optical, acoustic, radiographic, penetrant and other (such as vibration, leakage testing and integrated) methods of NDT and evaluation ...

Non-destructive Testing: Neutron Radiography

A scalarization-based method for multiple part-type scheduling of two-machine robotic systems with non-destructive testing technologies

This paper analyzes the performance of a robotic system with two machines in which machines are configured in a circular layout and produce non-identical parts repetitively. The non-destructive testing (NDT) is performed by a stationary robotic arm located in the center of the circle, or a cluster tool. The robotic arm integrates multiple tasks, mainly the NDT of the part and its transition bet...

Ultimate limitation of the SQUID magnetometer

The Superconducting QUantum Interference Device is used to detect weak biomagnetic signals since in the early seventies. In that time the measurement was based on point contact rf SQUIDs operated at 20 MHz, with to a flux noise of the order of 10-4 Φ 0/ √Hz . After finding methods to fabricate reliable thin-film devices, the dc SQUIDs started gradually replace the rf SQUIDs. [1] The dc SQUID wi...
