Further Light-tight Analysis

• Confirmed cables are light-tight. (constant
  signal of 3.4 nA w/ and w/o lights but w/
  fluctuations of /- 0.3nA)
• But how much of that is from photoelectrons of
  ambient light and not noise.
• Dark Current (2nA 20nA), likely to be dark
  noise...but best to get value for approximate
  ambient light signal in p.e.
• Located Light-meter in Optics teaching labs
• Found PMT Gain Curves online

Mold Modifications

• Expect Jon to be done by end of next week.
• Create sample connectors to test mold design.
• Redo Light-tight test.
• Ship mold off to FNAL?
• Mass Production?
