Elastic Recoil Detection of Hydrogen at IRMM
An experimental set-up for recoil spectrometry of hydrogen involving a stopper-foil, usually referred to as ERDA (elastic recoil detection analysis), has recently been implemented. The objective is to complement the resonant nuclear reaction analysis of hydrogen using the reaction hydrogen-1(nitrogen-15, alpha gamma)carbon-12, available on site, with a technique that is faster and more established although having the drawback of not as good depth resolution. A helium-4(+) beam of 2-4 MeV is utilised and the simultaneous detection of backscattered projectiles and hydrogen recoils is performed using 2 ion implanted silicon detectors. The data from various reference samples have been evaluated using several computer codes in order to unambiguously extract quantitative depth profiles.
