SQUIDs for a Toolbox of Sensors

By: Caitlin Hayes,  Cornell Research

A large, cube-shaped metal frame reaches almost to the ceiling. The frame supports, at its center, four canisters, one inside the next, that insulate a central chamber that drops down to 7.5 millikelvin, or roughly -460°F.

In that coldest chamber resides a sensor called a Superconducting QUantum Interference Device, otherwise known as SQUID. “So that’s also our lab mascot,” says Katja C. Nowack, Physics. Her lab is building two scanning probe microscopes (SPM), each with a SQUID at its heart.
