Run Plan

  • Chamber is filled with natural N2O


  • Cross sections:

The cross sections are shown in the following figure:

  • Expected rates:

The expected rates are calculated with 3 cm cell thickness and thin radiator.

  • The expected rates are shown in the following figure:

  • The expected rates from oxygen isotopes are shown in the following figure:

  • Run Plan:
  1. Start with beam at 6.5 MeV (kinetic)
  2. Increase beam K.E. by 0.1 MeV steps all the way to 8.5 MeV
  3. Reproduce the overall rate shown above
  4. At K.E. of 8.5 MeV, increase the chamber threshold by increasing the pressure. Suppress the 14N(γ,p)13C events.
