Nuclear Microprobe

Technical Data:

Home made, based on a HVEC KN-3000 type Van de Graaff accelerator with proton beam energy up to 2.5 MeV and energy stability of DE / E = 10-3. The focusing elements of the microprobe (two doublets of magnetic quadrupole lenses) were manufactured in the Micro Analytical Research Centre (MARC, Melbourne, Australia)
Energy of protons up to 2.5 MeV
Beam spot diameter: about 7 microns at beam current of 100 pA (sufficient for measurements using micro-PIXE or micro-RBS techniques), about 1 nA at beam spot of 10 microns
Measurement chamber characteristic:
X-ray Si(Li) detector, particle detector, two PIN diode particle detectors for off-axis STIM technique, channeltron for secondary electrons detection, charge collection from sample and from the Faraday cup, CCD camera (side view using a tilt mirror) with 120x objective, sample holder for 4 samples plus callibration sample, variable attenuation filter

Application:

Environmental studies, bio-medical research, material engineering.
