An experiment to study strong electromagnetic fields at RHIC

Description: We present a description of an experiment which can be used to search for effects of strong electromagnetic fields on the production of e{sup +}e{sup {minus}} pairs in the elastic scattering of two heavy ions at RHIC. A very brief discussion of other possible studies of electromagnetic phenomena at RHIC is also presented.

The design of the RF cavity for the heavy ion storage ring for atomic physics

Description: An rf cavity and drive system have been designed for the proposed Heavy Ion Storage Ring for Atomic Physics,'' HISTRAP, at Oak Ridge. A peak accelerating voltage of 2.5 kV per turn is required with a continuous tuning range from 200 kHz through 2.7 MHz. A single-gap, half-wave resonant configuration is used with biased ferrite tuning. The cavity structure is completely outside of the beam line/vacuum enclosure except for a single rf window that serves as an accelerating gap. Physical separation… more

Ecr (Electron Cyclotron Resonance) Source for the HHIRF (Holifield Heavy Ion Research Facility) Tandem Accelerator

Description: Electron Cyclotron Resonance, ECR, ion source technology has developed rapidly since the original pioneering work of R. Geller and his group at Grenoble in the early 1970s. These ion sources are capable of producing intense beams of highly charged positive ions and are used extensively for cyclotron injection, linac injection, and atomic physics research. In this paper, the advantages of using an ECR heavy-ion source in the terminal of the Holifield Heavy Ion Research Facility (HHIRF) 25-MV tan… more

High-resolution heavy-ion-induced x-ray satellite emission study of implanted sulfur as a probe of co-implanted oxygen in an oxide substrate

Description: Using high-resolution measurements, the relative fluorescence yields of the sulfur K{sub {alpha}}L{sup n} x-ray satellite lines produced by 24 MeV Si{sup q+} ion irradiation of a series of quartz glass targets co-implanted to equal doses and depths of sulfur and oxygen have been obtained and compared to the yields from a series of quartz glass targets implanted to the same depth with sulfur only. The data exhibit lower yields in the higher-order KL{sup n} satellite lines for the co-implanted ox… more
