1- Bubble Chamber progress at Argonne:

Notes from this meeting:

Test Bremsstrahlung beam and Penfold-leiss unfolding
Measure sensitivity to gammas (of interest to dark matter search, now at 10^-10)
Measure ¹⁹F(γ,α)¹⁵N cross section at low energy (E_electron = 4 - 7 MeV)

 # Ready to fill with mercury and N<sub>2</sub>O - planned for next week
 # Need to do thermal modeling of temperature gradient across chamber
+# Argonne will build short stand for chamber to fit JLab beamline
-* Fluorine chamber is still of interest:
