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)
  3. For the waiting time of 72.07 µs, part of this time (70 µs) is to allow for the Pockels Cell flipping. In the future, the Pockels Cell flipping time will be improved to 12 µs. How would this affect the injection scheme?
  4. Is it possible to have transversely polarized electrons at interaction point (IP)?
