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)

+'''Notes from this meeting:'''
+* Bubble Chamber:
+# 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 C<sub>4</sub>F<sub>10</sub> is still of interest:
+# Test Bremsstrahlung beam and Penfold-leiss unfolding
+# Measure sensitivity to gammas (of interest to dark matter search, now at 10<sup>-10</sup>)
+# Measure <sup>19</sup>F(γ,α)<sup>15</sup>N cross section at low energy (E<sub>electron</sub> = 4 - 7 MeV)
+* JLab Schedule:
+# At 2K from June 20<sup>th</sup> to September 30<sup>th</sup>
+# Now we have a clear path forward for obtaining pressure vessel approval
