TR-19 Cyclotron

The TR-19 Cyclotron, built by Advanced Cyclotron Systems Inc. Vancouver, Canada, is a versatile, fully automated device that vertically accelerates negative ions (H^-) from an external source to an energy of 14-19 MeV. (variable). TR-19 is equipped with two proton extraction ports by stripping hydrogen ions of pyrolytic carbon sheets, which can operate simultaneously, providing the proton beam with a total current up to 300 μA. With a double irradiation capacity TR19 can provide the necessary medical radioisotopes for PET (Positron Emission Tomography) at national level, while maintaining the potential for further development. With the help of this accelerator 15 Ci of ¹⁸F / hour of irradiation can be obtained; simultaneous dual irradiation and a wide range of radioisotopes for PET imaging (¹⁸F, ¹¹C, ¹⁵O, ¹³N, ¹²⁴I, ⁶⁴Cu, etc.).

3 MV Tandetron

The 3 MV Tandetron accelerator, manufactured by High Voltage Engineering Europa B.V., was installed and commissioned in 2012, being dedicated especially to applied research. This installation is fully equipped to perform studies of materials with accelerated ion beams (IBA - Ion Beam Analysis), ion implants (IIB - Ion Implantation Beamline) and radiation resistance tests for various types of advanced materials, as well as measurements of effective reaction sections (CSM -Cross-Section Measurements), of interest in nuclear astrophysics.

1 MV Tandetron

Accelerator Mass Spectrometry (AMS) is the most accurate method of analyzing isotopic ratios. Using a particle accelerator, usually a tandem type, an AMS spectrometer can identify the investigated isotopic species ion by ion. Tandem electrostatic accelerators are preferred for this application due to the possibility of removing a good part of the unwanted molecular interferences, through the Coulomb explosions that take place during the phenomenon of stripping of negative ions. Thus the sensitivity of the AMS method can reach a rare isotope / abundant isotope ratio of 10^-15 or in other words an atom can be identified among others one billion billion, which means a huge advantage for applications in various fields of research: medicine, paleogeomorphology, geology, archeology, atmospheric physics, paleoclimatology, nuclear astrophysics, environmental radiocontamination, etc.

An ECR source for ion implantation

The heavy ion source RECRIS (Romanian ECR Ion Source) operates on the basis of the cyclotronic electronic resonance (ECR) phenomenon. In ECR type sources, the deep ionization of the gas atoms present in the plasma chamber is obtained by successive collisions with relatively high energy electrons, obtained by stochastic heating in an ECR type plasma, formed by resonant energy absorption from an electromagnetic field. of very high frequency and confined by the superposition of strong axial and radial magnetic fields with special configurations.
