Tandetron Accelerator with terminal voltage of 2 MV, designed by the High Voltage engineering Europa B. V has been operational at Piestany, Slovakia since November 2016. It is capable of deliver protons or deuterons beam with energy from 100 keV up to 4 MeV. It can also accelerate the alpha particle beam up to 6 MeV. Nuclear reaction 2D(d,n)3He will be mainly used for neutron production within the frame of current project at Piestany. The employment of gas cell appears to be most optimal, since it provides sufficient yield of neutrons. The state of art D2 gas target has been designed for neutron production after critically examining gas target facilities at ATOMKI, Debrecen [1] and PTB, Braunschweig [2]. The simulation of neutron production from gas target has been carried out by DROSG [3] code. Neutron shielding and safety calculations have been performed by MCNP code [4]. Further, it is planned to measure 20Ne(α,γ)24Mg cross-section at stellar environment using 2 MV Tandetron. For aforementioned proposed experiment, the implanted neon targets (20Ne and 22Ne) were produced using 200 kV ion implanter facility HZDR, Dresden, Germany. These targets have been recently characterized by using 6 MV Tandetron Facility at Trnava, Slovakia. The Nuclear Resonance Analysis (NRA), Proton-Induced X-ray Emission (PIXE) and Rutherford back scattering (RBS) methods were employed for the characterization of implanted neon targets.
