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