A 2,5 MV Van de Graaff accelerator with three
experimental beam lines, with all the relevant ion
beam techniques available: RBS, PIXE, NRA, Channeling,
ERDA and NRB with (p, g).

An Oxford Microbeams® type nuclear microprobe with
a lateral resolution of 1,5 mm. It is possible to
perform PIXE, RBS, STIM (Scanning
Transmission Ion Microscopy), CSTIM (Channeled
STIM), IBIC (Ion Beam Induced Charge) and IBIL (Ion Beam Induced Luminescence) type of analysis, in normal
conditions and external beam.

An 210 kV Ion implanter with a chamber allowing the
implantation of an area of 20x20 cm². It is possible to carry
on implantation samples in the temperatures range of 77 K
up to 1273 K, in a controlled way. The connection of the
implantor to the RBS chamber of the van the Graaff
Accelerator, allows in situ analysis.

A 3 MV Tandem accelerator, equipped with an
accelerator mass spectroscopy (AMS) system with
a lateral resolution of 30 mm.
 

The Hotbird is a multipurpose instrument with
applications ranging from the phase identification
and determination of residual stresses on polycrystalline
alloys to two-dimensional mapping of Bragg peaks
in single crystalline materials. This instrument can
perform diffraction experiments from room temperature
up to 1400 ºC allowing in situ studies. These
high temperature experiments are very useful
and also very rare.

D8 diffractrometer from Bruker AXS is a versatile
equipment for materials characterization. Its
applicability extends from high resolution X-ray
diffraction/reflection measurements of single
crystals and advanced quantum heterostructures
to high-intensity powder diffraction of polycrystalline
materials. Important structural information from 3D
heterostructures such as strain in high quality
superlattices layers of combined crystals, 2D embedded
quantum wells in a matrix, 1D quantum wires, 0D quantum
dots and grain size/strain of powders are accessible
in this powerful equipment.
