\begin{enumerate}

    \item What is a Josephson Junction?
    
    \item What is a Cooper Pair?

    \item How does the DC Josephson effect work? What is the AC Josephson effect? How are they useful?

    \item Why is it important to know the number 2e/h; what does it mean?

    \item How do you construct the Josephson Junction used in this experiment? (Hint 4 wire junction)

    \item Explain how you remove the junction assembly from the probe and put it back in. Which way do you turn the set screws?

    \item Did you notify a professor or GSI about filling the liquid helium tank one day before starting the lab?

\begin{enumerate}

    \item Show your photo of the DC effect with calibrated axis and photo of the AC effect, with calibrated axis, to a GSI. Also you present your measured corrected value for 2$e/h$, with uncertainty, to an instructor and ask for a signature.
