The LATR comprises unique equipment and infrastructures in Portugal. During the year 2008, and within the framework of the re-equipment programme, several researchers and technicians of the Unit were pretty much involved in the upgrading and installation of new experimental equipment or facilities.

In addition, the research activities covering different topics in Advanced Materials, Environment, Health and Biomedical Sciences followed the approved time schedule and were supported exclusively by external funded projects. Along with scientific achievements, the post graduated formation was maintained with the engagement of graduated students in the research activities, leading to MSc and PhD theses. The strategic collaborations with Institutions and Universities worldwide were strengthened and were fundamental to maintain the high scientific production of the Unit.

1. Research Activity Groups

It comprises the following research groups:

Ion Beam Laboratory

 Nuclear Instrumentation
   Radiation Technologies

2. Equipment and Devices

Main equipment operated are the following:

  • Ion Beam Laboratory (IBL) equipped with a 2,5 MV Van de Graaff accelerator with a nuclear microprobe which comprehends an external beam,  a 3 MV Tandem accelerator with a AMS Line and a 210 kV high fluence ion implanter. Major activities are in the fields of advanced materials,  environment and biomedicine sciences and nuclear physics.
  • High Resolution High Temperature X-Ray Diffraction Laboratory (MA3T) host a high-temperature double crystal X-ray diffractometer (Hotbird) and a high resolution difractometer. Major activities are centered on the study of multiple quantum wells and quantum dots structures (QD).
  • Radioactive Isotopes Solid State Laboratory, located at Isolde/CERN, is equipped with two goniometers and position sensitive detectors for emission channeling studies. A hyperfine emission interactions setup is also available and major activities are in materials science research (see also IS453; IS481; IS487).
  • Neutron Diffraction Laboratory, installed in the Portuguese Research Reactor (RPI), comprises two diffractometers (ETV, DIDE) and one spectrometer (EPA) which are under development. Foreseen applications are in the field of crystallography and magnetic structures.
  • Nuclear Instruments Laboratory develops nuclear instrumentation. The activity extends also to modelling and simulation of gamma, electron and neutron fields and of low temperature gas discharges.
  • Characterization Polymer Laboratory study the copolymerization, reticulation and others effects induced by gamma radiation, in order to improve the properties and biocompatibility of new materials to be used for biomedical and environmental applications.
  • Radiation Technology Laboratory comprises a research Cobalt-60 facility* with a semi-industrial dimension,  a clean controlled environment laboratory LETAL (Laboratório de Ensaios Tecnológicos em Áreas Limpas) and an ionizing radiation facility IRIS  (Instalação de Radiações IonizanteS). The research activity is centered on the study of the impact of radiation on water treatment and biological products.
