I suspect Feng and/or Xiangdong will reach out to you soon to discuss. So I agree, sending the email sooner rather than later is a good idea.<span class="x_Apple-converted-space"> </span><br class="">

both on the physics, and on the potential to create university bridge positions. At the moment, we’ve had discussions with participants at ANL, JLab/Hampton/WM, Temple, UConn.<br class="">
