MTA Atomki has installed the new Tandetron accelerator in May 2014 made by High Voltage Engineering Europa BV. In January 2015 a Duoplasmatron ionsource with the injector magnet, then a simple temporary switching magnet was installed. The Tandetron accelerator needs negative ion input and then produces high energy positive ion beam (in this case protons). The preliminary arrangement immediately allowed to start developing an external beam setup and a target chamber for nuclear astrophysics. The first scientific result made in this target chamber was presented at the European Nuclear Physics Conference EuNPC2015 in Groningen, the Netherlands and it was awarded the 'Best poster prize'.
