Very first test results obtained from an intrinsic single crystal CVD diamond detector are described and compared to those measured with polycrystalline CVD-diamond and HPHT Ib diamond sensors. The data are discussed in the context of the requirement

In this paper we study the emission of 8Begs, B and N fragments in the interaction of 16O ions with 59Co, 93Nb and 197Au at incident energies varying from 6 to 25 MeV/nucleon. The spectra of these fragments, as well as those of C fragments studied in

The ongoing need for single crystal diamond of high quality in physics research and application, has been amply demonstrated. This need cannot be satisfied by access to natural diamonds. In recent years much progress has been made in the synthesis of

Two different reaction mechanisms (which both occur at very short interaction times) contribute to the emission of intermediate mass fragments in reactions induced by a light nucleus such as 16 O. They are the binary fragmentation of the projectile a

Damage profiles in diamond after irradiation with 75 keV carbon ions at implantation temperatures ranging between 77 and 600 K were determined by ion channeling analysis in a backscattering geometry. Critical damage energies for irreversible transiti

The defect that has almost exclusively occupied attention has been that associated with nitrogen. With the advent of quantitative nuclear analytical techniques it has become evident that, in natural diamond, hydrogen and oxygen are also major impurit

For several years now, the ESRF, the University of the Witwatersrand and Messrs. De Beers Industrial Diamonds (Pty) Ltd. through their Diamond Research Laboratory, have pursued a development programme to assess and improve the quality of synthetic di

The spectra of 8Begs fragments emitted in the interaction of 100, 200, 300 and 400 MeV 12C with 59Co, 93Nb and 197Au have been measured and analysed. Our analysis suggests that, before breaking up, 12C may suffer a considerable energy loss which incr
