Facilities of the Centre
NEC 5U Pelletron accelerator with RIEF funded upgrade to make it one of the brightest accelerators in the world for nuclear microprobe operation ($2,000,000+)
Two MeV ion microprobe beam lines and associated instrumentation ($1,000,000 each)
Dilor confocal Raman spectrometer ($500,000) Joel UHV AFM ($700,000) Distributed computer network of one DEC Alpha workstation
and more than 20 satellite workstations and PC's ($100,000). Pulsed Laser Deposition System ($1,000,000) This combination of instruments is unique worldwide for one
research Centre!

Conclusions
Structural characterisation:– Spatial resolution of for conventional IBA 0.4 m– Elemental sensitivity with PIXE 10 ppm – Depth resolution with RBS 50 nm – Lattice location studies with ion channeling
Electrical characterisation– Spatial resolution for IBIC 0.1 m– Mapping of charge trapping an recombination centres
Sub-trace optically active colour centres with luminescence 3D density and elemental mapping with tomography Stay tuned for further developments......
