Attended: Moskov, Sean. Justin, Mikhail, Jim, Hovanes, Eugene, Pavel, and Igor.

  • The transition fluence for void swelling in irradiated pure copper is the issue as Bogdan pointed out. First of all, thank you, Pavel, for sending us a nice overview [1]. Actually, the main source of the problem is (n, alpha) and (n,t) reactions and the bottom line is to prevent a transition fluence for void swelling in irradiated pure copper, we have to (1) keep the temperature of our Cu radiator below 200°C (2) use Cu with 2%Be and/or 3.5%Ti.
  • Hovanes will talk to Bogdan and this task.
  • Moskov will talk to accelerator folks about a beam test.
  • Eugene said that JLab Physics Division (Rolf) the Lab would be able to provide up to $2M for the KLF project.
  • Let us meet in a month, June 22nd.
  • Let us have a new KLF Collaboration meeting in September.
