A Positive Spin

Beams with polarized particles greatly boost the physics output of high energy physics colliders. While it has been straightforward to make polarized electron beams, polarizing positrons is more difficult, especially in the case of linear colliders. The E-166 experiment has successfully demonstrated a technology to make a polarized beam of positrons for a future linear collider.
