Procedure for Conducting Polarized Electron Reflection Measurements at One Beam Energy

1. Either an ascending or a descending order was chosen for incident beam currents $F$. If the procedure being described here had been performed previously, then the order chosen was opposite to that chosen in the preceding performance of the procedure. Otherwise, an order was chosen at random.
2. The electron gun beam current was varied, in the chosen order, in $2\,\mathrm{\mu{}A}$ steps between $2\,\mathrm{\mu{}A}$ and $6\,\mathrm{\mu{}A}$.
3. At each of the beam currents, a series of electron arrival rate measurements was taken, according to the procedure in appendix A.4.
