Tristan, an electron‐positron collider at KEK, the National Laboratory for High Energy Physics at Tsukuba, Japan, achieved collisions with 25 GeV in each beam in mid‐November. At that time the maximum luminosity was 2.6×1029/cm2 sec. This center‐of‐mass energy of 50 GeV makes Tristan the world record holder for electron‐positron collisions, at least until the SLAC Linear Collider starts colliding‐beam trials, scheduled to begin next month. SLC will have 50 GeV in each beam.
