1000 Filled LN2 cold trap.
  • PSD data was again taken for each ionization channel using the same fan setup as on 2012/06/04.
  • Data was taken for the following configurations:
    • At Rest: The fan was turned off
    • Fan - No Contact: The fan was on, but not in direct contact with the needle valve.
    • Fan - Contact - 0 Ohms: The fan was on, in contact with the needle valve, and was powered with the aluminum-foil-wrapped, 9V battery.
    • Fan - Contact - 1.5 Ohms: The fan was on, in contact with the needle valve, and was powered with the aluminum-foil-wrapped, 9V battery with a 1.5Ohm resistor in series.
  • Figure 1 shows the PSD data taken for each ionization channel.
