SEM Images

SEM image of junction for the Josephson Bifurcation Amplifier (JBA)

The Cavity Bifurcation Amplifier (CBA). The top image shows the cavity resonator. The bottom right and left images are the in and out capacitors. The middle image is the junction at the center of the resonator.

Plassys E-Beam Deposition System

The PLASSYS can evaporate thin films of Al, Cu, Nb, Au, Ta, and Cr with a base pressure of 1x10 -8 mT. The sample holder has two main axes of rotation. It is housed in a load-locked chamber with an ion mill.

The Qlab group in 2003.

Post-doctoral fellows Frédéric Pierre (far left) and Chris Wilson (3rd from right) have since left for France and Sweden, respectively.
