NOTRE DAME UNIVERSITY HAS NEW ATOMIC GUN

An electrostatic type of high-voltage generator with which scientists hope to create the tiny elemental particles known as positrons has now been installed at the physics laboratories of the University of Notre Dame. Under the direction of Prof. G.B. Collins, two graduate students, R.J. Schager and A.L. Vitter, have built the giant apparatus shown on the front cover of this week’s Science News Letter.
