Description
Neutron activation analysis (NAA) is a highly sensitive method of chemical analysis with neutrons. The FRM II provides flux values of up to 10^14 /cm^2s in selected irradiation positions near the reactor core. The high degree of thermalization is optimal for analysis, as corrections due to interfering reactions are usually negligible. The irradiated samples can be transported via a rabbit system from the FRM II to a laboratory in the Radiochemistry Munich (RCM) building, where three counting stations are available. Their electronics (spectrometers) have recently been upgraded so that advanced features, e.g. list mode, can be implemented.
The detection limits are low, in certain cases they even reach the ppq range. The capabilities of the PGAA and NAA instruments complement each other. The advantages and limitations are described in detail on the poster. The NAA instrument is not dependent on status of the cold source.
