Polhe3 meeting 20120418

• progress
  • after checking optics, Boris polarization is still low and dropping. see [1]
  • finished AFP loss test for Cell Gravy. see details [2]

• todo
  • • Use the Moss cell to check system again.
      • masing effect for Moss cell ( polarization ~ 20%), details see [3] and [4]
      • set up the gradient coil
      • test different currents and thresholds
      • test the new method to destroy target chamber polarization for diffusion model.
    • if system OK. we will do following (2 weeks):temperature optimization and diffusion test (225~240, may add point 220)
      • temperature stabilized ~ 4 hours
      • spin up ~ 24 hours
      • do EPR
      • do internal temperature test (do NMR laser on - off - on)~ 1 hour
      • do AFP loss with laser on, check immediately
      • do diffusion model ~ 4 hours
      • wait for another 3~6 hours, or we can put it in diffusion test.
      • do AFP loss with laser off, check immediately
      • do hot spin-down ~ 12 hours
      • do one cold spin down for this cell after finishing all temperature tests ~18 hours
