Meeting Time: 12:00 pm CDT

Connection Details:

We will use Big Blue Button. Instructions below.

1. Go to the following website: http://shemp.physics.smu.edu/physics/index.jsp
2. Enter your name in the box 'Full Name'. This is how your name will be displayed for everyone to see.
3. Select 'Virtual Room - AARM Conference Room' from the pull down session menu.
4. Enter the pswd for the conference.
5. Hit the 'Join' button.

Ideas:

• Effectiveness of plate-out reduction when materials are stored under purge (JC).
• Experiments to test plate-out in an electric field (JC)
• Effectiveness of various cleaning techniques (which ones?) (JC)
• Plate-out rate determination, standardization, and characterization (JLO)
  • Use e-formed copper plates as a witness plate. Perform a hard etch to begin.
  • Expose plate to a known concentration of Rn in air under three cases: No flow, low flow, high flow.
  • After fixed period of time, remove plate and isolate.
  • Wait for everything to decay to Pb-210.
  • Etch to remove and capture Pb-210. This is the hard step we need to make quantitative.
  • Perform a MS measure to get the Pb-210 concentration.

Resources:

• PNNL:
• SMU: We currently have an XIA alpha particle counter, purge box and fume hood access. We are considering the purchase of a radon source for controlled exposures.
• Syracuse:
