Physics and Engineering students build microscope

The Scanning SQUID Microscope is being constructed in the Physics Research Lab in the Greathouse Science Building.

Professor Fred Cawthorne is currently leading a team of students in the construction of a Scanning SQUID Microscope (SSM).


Using a very sensitive magnetic field detector called a SQUID (Superconducting Quantum Interference Device), the microscope is used to create a magnetic image that allows one to “see through” solid material and to locate defects, or short circuits, in circuits.


Much of this work is supported through a collaboration with Neocera, LLC., a company that makes a commercial SSM.
