Tandem 3MV Accelerator
![tandem](/images/instalaciones/tandem.jpg)
Ions are produced by three ion sources. The first one is based on radiofrequency techniques (Alphatross) and generates negative ions from gases (H, He, N, ...). There is also a caesium sputtering source (SNICS) which produces negative ions from solid samples. The most recent one is a Duoplasmatron source, which is very reliable and provides a high-brightness beam. The sources are connected by ports to an injection magnet that selects the desired ion mass.
In the two-pellet chain tandem accelerator, the selected ions are accelerated with a maximum terminal voltage of 3 MV. The beam line, which is situated after the accelerator, includes several instruments for focusing, steering and monitoring the beam. At the line end, the beam can pass directly to the 0° line or it can be deflected by the switcher magnet towards one of the five beam lines.
Photons and particles are detected using standard detectors: SiLi and LEGe from Canberra, an Ortec HPGe, a NaI(Tl) detector and ion-implanted silicon detectors.
