Inspired by the 1964 James Bond classic, we have built the Coldfinger. It is a crafted piece of copper that mounts at the coldest point of a dilution fridge. This is where the sample lives. It has an elongated shape because it needs to enter into the bore of a superconducting magnet, which is typically 2 or 3 inches in diameter.
The Coldfinger has PCB-based filters to cool down electrons that come from room temperature in order to explore our devices.
The Coldfinger was produced by our excellent machine shop and electronic shop at Pitt.
