A Positron Source for JLAB

Year 1

  1. Install positron beam line.
  2. Check positron productions efficiency simulations for 10-20 MeV electrons on Tungsten Target
  3. Investigate differences between simulation and data, most likely need another week of beam to change configuration

Year 2

  1. Measure production efficiency for different Tungsten converter target thicknesses (100 microns -> 1mm in 100 micron steps)
  2. Measure positron emmitance and compare to simulation predictions
  3. Measure brightness as a function of quad setting (quads change emmitance)
  4. measure positron output as a function of beam current
  5. Begin designing tungsten converter capable of handling high heat load
  6. CEBAF can accept particles into acceleration stage as long as [math]\frac{\Delta E}{E} \leq 10^{-3}[/math]
  7. Electrons are injected at 500 MeV (1 GeV) for a 6 GeV (12 GeV) CEBAF. Currently [math]\frac{\Delta E}{E} \leq 10^{-5}[/math]

Year 3

  1. Test design configuration from Genetic Algorithm at the IAC
  2. measure tungsten converter target performance as function of IAC beam current
  3. IAC beam is x 40 less power than what will be needed at JLAB

Parts list

  1. FC $5k 400 W max power
