Description
The Centro de Micro-Análisis de Materiales (CMAM) is one of the two research centres with an ion accelerator in Spain. It belongs to the Universidad Autónoma de Madrid (UAM) and the building that hosts the laboratory is at the university campus.
The equipment of the facility consists on an electrostatic ion accelerator with a maximum terminal voltage of 5 MV and six beam-lines dedicated to various application areas such as the analysis and modification of materials, the study of the nuclear reactions or archaeometry studies. The accelerator, built by High Voltage Engineering Europe (HVEE), is of the tandem type with a Cockroft-Walton acceleration system. It is provided with two sources: a plasma source for gaseous substances and a sputtering source for obtaining any element from H to U from a solid target.
The accelerator feeds up six beam-lines after the bending magnet at different angles: the standard multi-purpose line which ends in the internal micro-beam line, the time of flight line, the implantation line, the external micro-beam line and the nuclear physics line. For a more detailed description of each line, see Ref. [1]. There are two lines where the beam can be extracted from vacuum to air: the implantation line (IMP) and the external micro-beam line (EuB). Until now, the first has been devoted to the implantation or irradiation in large areas for material modification. The second has been focused onto archaeometry studies. Now, a new project has started to use this two lines for proton-therapy preclinical studies.
What will be presented at the conference is the characteritzation of the pulsed beam in air obtained in the IMP line. The main aim of this beam-line is to perform homogeneous implantations or irradiations in large areas (up to several cm$^2$). For this purpose, the line has a HVEE electrostatic scanner consisting of four plates for vertical and horizontal beam deflection and the corresponding power supplies. This system is capable of scanning Hydrogen of 10 MeV at a size of 100×100 mm$^2$. Until recently, this system, called RASTER, has been used merely for scanning and irradiating large areas. However, it can open the door to obtaining external pulsed beams for pre-clinical studies on proton-therapy in the FLASH regime.
