This video accompanies the Josephson Junction Experiment, providing students with an introduction to the theory, apparatus, and procedures.
Superconducting phenomena are among the most fascinating features in physics, and the Josephson Effect is the most interesting of all. In 1962, Brian Josephson predicted that electron pairs could tunnel without resistance through an insulating barrier between two superconductors. Here we use a point contact between niobium wire with a thin oxide layer and a niobium screw at liquid helium temperatures. Both the DC and AC Josephson effects are observed and measured. A DC current can flow through the junction with no potential difference, but when a DC voltage is applied together with a small alternating voltage, the I-V curve shows a characteristic step structure. From this step structure the value of 2e/h can be calculated easily and accurately, an exciting consequence of the properties of the junction.
In this experiment you will learn some low temperature techniques and four wire measurements that are used in many research laboratories.

UC Berkeley incoming freshman attended a presentation addressing important issues faced by college students: sexual assault and harassment, mental health, and alcohol use.
David Suratt, Berkeley's associate dean of students, welcomed students with a challenge and an invitation: to become active participants in managing the dangers of sexual violence and harassment, mental-health problems and alcohol abuse, to take responsibility for their own well-being and that of the larger campus community.
