3MV Tandetron


The 1 MV Tandetron™ machine was installed in 2012 at the National Institute for Physics and Nuclear Engineering IFIN-HH, Bucharest Romania [1]. This facility represents the second Accelerator Mass Spectrometry (AMS) laboratory at IFIN-HH having the goal not only to continue, but mainly to enlarge the research area of this highly sensitive analysing method. The multi-element AMS was developed by HVEE to measure 14C, 10Be, and 26Al, and 129I. More recently the system was optimised for actinides measurements. The device from Bucharest is based on a 1 MV tandetron, with a Cockcroft–Walton type high power supply and two separated ion beam injectors at 120°. The existence of a bouncing system and of a fully automated control system of the ion beam transport and diagnose, makes possible a precise tuning of the entire analyzing system. It also permits a permanent monitoring of an AMS analyze. The AMS machine construction concept proved to be very efficient for removal of ion interferences in the analyzing experiments. The precision of carbon quantitative analysis was better than 4‰ and the background was found to be lower than 2 × 10^(−15).
