Book Description
A beam propagation experiment is being prepared to test theoretical predictions about transverse instabilities in a heavy ion beam with large space-charge effects in a long quadrupole transport system. The 200 keV injector which has the features of variable current density and variable emittance has been constructed. The Cs+ pulsed drift tube injector model continues to operate for studies of beam optics, component testing in an intense ion-beam environment, and diagnostics development. The electron-beam probe has now yielded successful results on the time-resolved charge density of the Cs+ ion-beam. It has revealed the existence of a significant number of electrons surrounding the ion-beam. The theory of longitudinal instabilities has been advanced. Improvements to the EGUN and other beam-dynamics codes continue and have yielded valuable results. Transport of high-intensity beams in an A.G. octupole system is under active study.

Book Description
Highlights from this reporting period are as follows: (1) the 200 keV cesium ion injector for the Single Beam Transport Experiment has been operated extensively in development and measurement of the quadrupole matching system and beam emittance control. Construction of the complete transport system is well advanced; (2) beam diagnostic tools continue to be improved. The electron beam probe has been used extensively to study ion beams in varying stages of charge neutralization. Development of systems using scintillators and the EG and G Optical Multichannel Analyzer (OMA-2) continues; (3) the Long-Pulse Induction Module (LPIM) is in the final stages of construction. A two-core prototype test cell has been assembled and tested to nearly 106 pulses. Development of both the switch tube (ignitron) and pulse-forming network has proceeded rapidly and successfully; (4) silica-loaded polymer insulator development is continuing at a low level; and (5) theoretical studies of longitudinal beam bunch dynamics using I. Haber's computer simulation code, quadrupole and octupole transport channels and solenoid focussing channels using neutralized beams have received considerable emphasis during this time. The exploration of possible induction linac parameters for a High Temperature experiment (HTE) is continuing.
