LARGE ANGLE SPECTROMETER.

THE SUPERHILAC IS A LINEAR ACCELERATOR USED FOR LOW ENERGY NUCLEAR SCIENCE RESEARCH AND IS ALSO THE INJECTOR FOR BEVA- LAC. BEAMS OF TWO DIFFERENT IONS CAN BE PRODUCED ON ALTER- NATE PULSES AND DELIVERED TO ONE OR TWO SUPERHILAC EXPERIMENTERS AND TO BEVALAC. FIVE MAJOR BEAM LINES ARE CURRENTLY IN OPERATION AT THE SUPERHILAC. AT THE BEVATRON, RESEARCH IS CONDUCTED IN MEDIUM TO HIGH ENERGY HEAVY ION NUCLEAR PHYSICS, PLUS CLINICAL TRIALS FOR HEAVY ION RADIOTHERAPY. EIGHT BEAM LINES ARE AVAILABLE AT THE BEVATRON/BEVALAC. MEASUREMENTS OF VARIOUS PHENOMENA SPECIFIC TO HEAD-ON COLLISIONS BETWEEN HEAVY IONS ARE BEING CONDUCTED AT THE LAWRENCE BERKELEY LABORATORY BEVALAC BY THE CHAMBERLAIN/NAGAMIYA GROUP, AN LBL-JAPANESE COLLABORATION. MULTI-WIRE PROPORTION-AL CHAMBERS BEFORE AND AFTER THE MAGNET DETERMINE THE TRACK OF FRAGMENTS EMITTED AT LARGE ANGLES. THE SPECTROMETER IS ROTATABLE BETWEEN ANGLES 0 DEGREES AND 180 DEGREES AND DETECTS PIONS AND LIGHT FRAGMENTS.
