Miscellany

The Atomic Energy Commission is reported to have allocated $250,000 for studies of the feasibility of high‐energy synchrotron focusing by alternating‐gradient magnetic and electric fields, a technique that is hoped to make possible the construction of accelerators with energies conceivably ranging upwards as high as 100 Bev. The studies will be carried out by groups at Brookhaven National Laboratory, Princeton University, and at Harvard and the Massachusetts Institute of Technology. The theoretical basis for alternating‐gradient focusing was described in the paper by Ernest D. Courant, M. Stanley Livingston, and Hartland S. Snyder, Phys. Rev. 88, l190 (1952).
