Ion Beam Laboratory(Unit of Physics and Accelerators)


Laboratory of Accelerators and Radiation Technologies

The Laboratory of Accelerators and Radiation Technologies (LATR), of the Nuclear and Technological Campus (CTN) has a long standing collaboration with research groups from the university and other research institutions, both national and international. Most of the IBL researchers are also members of the Nuclear Physics Centre (CFNUL) and this association was crucial for the development of the IBL.

2. Equipment and Devices

This infrastructure has 5 major equipment:

2,5 MeV van de Graaff Accelerator photo

Fig. 1 (left): 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).

Oxford type microprobe


Fig. 2 (right): 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.

Implantation chamber photo


Fig. 3 (left): 210 kV Ion implanter has 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.

Tandem accelerator.

Fig. 4 (right): 3 MV Tandem accelerator, equipped with an accelerator mass spectroscopy (AMS) system with a lateral resolution of 30 mm. The installation of a 14C dedicated line is foreseen [REEQ/814/CTM/2005].
