   1. Is it possible to have spin flipping in the electron ring similar to the ion ring?
   2. For the waiting time of 72.07 us, part of this time is for the Pockels Cell flipping which is nominal at 70 us. In the future, the Pockels cell flipping time will be improved to 12 us. How would this affect the injection scheme?

Questions to Vasiliy and Fanglei:
  1. Is it possible to have spin flipping in the electron ring similar to the ion ring?
  2. Instead of filling two helicity trains (+ gap - gap) in the electron ring, each 1540 bunches, is it possible to fill the ring with four helicity trains each 770 bunches? (e.g., + gap - gap + gap - gap)
