A Positron Source for JLAB
Year 1
- Check positron productions efficiency simulations for 10-20 MeV electrons on Tungsten Target
- Measure positron emmitance and compare to simulation predictions
- Repeat above measurements at different tilt angles
Year 2
- Use Genetic algorithm with Simulation predictions to optimize positron production
- Begin designing tungsten converter capable of handling high heat load
- CEBAF can accept particles into acceleration stage as long as [math]\displaystyle{ \frac{\Delta E}{E} \leq 10^{-3} }[/math]
- Electrons are injected at 500 MeV (1 GeV) for a 6 GeV (12 GeV) CEBAF. Currently [math]\displaystyle{ \frac{\Delta E}{E} \leq 10^{-5} }[/math]
Year 3
- Test design configuration from Genetic Algorithm at the IAC
- measure tungsten converter target performance as function of IAC beam current
- IAC beam is x 40 less power than what will be needed at JLAB
