Integrating Novel Cryogenic Research Tools in the Nanoscale Workstation

Posted 10 March, 2016

As the team here at Montana Instruments gears up for next week’s APS March Meeting in Baltimore, we wanted to take a minute to reflect on some of the accomplishments our customers have made in the field of low temperature research. One of those groups, the researchers at the UC Santa Barbara Jayich Lab, have continued to explore new frontiers through the development of novel cryogenic tools. They’ve done it again, adding another key technology to the world of optical cryostats.

The photo below shows the Montana Instruments Nanoscale Workstation with an integrated three axis Helmoltz coil superconducting magnet. The magnet provides fields of 1000 gauss in each of the three axes, or 0.5 Tesla vertically. Postdoctoral Associate Matthew Pelliccione reports:

“We are using Keithley power supplies with custom circuitry for field stability and diode protection in the event of a quench. By far the most difficult part of the installation was designing and testing the high Tc leads so an acceptable amount of heat was sunk both at the radiation shield and the platform. We are running 10 A on each coil when the field is maximized, so 30 A total current into the fridge…I now have it working nicely and can apply up to 1000 G fields along an arbitrary direction, and up to 5000 G along Z.”

Principal Investigator, Ania Jayich, is well known for her work in magnetometry and spin-phonon coupling in resonators.

This system is built around the Nanoscale Workstation, which is our largest sized base sample platform. It offers an inside diameter of ø197mm with an expansive cold breadboard platform of ø175mm, providing researchers the flexibility to integrate a variety of components and experimental setups.
