Abstract

A new micro-NRA set-up for boron analysis has been developed at the Debrecen scanning nuclear microprobe facility. It consists of four large area PIN silicon photodiodes in an optimised geometrical arrangement providing 1.87 sr solid angle. The new set-up was calibrated for boron in the low concentration region with NIST type glass standards and also with a macusanite glass standard. The calculated MDL value for boron was 5 μg/g for 1 μC accumulated charge in a glassy matrix. The capability of this set-up for precise concentration measurement is demonstrated via the analysis of geological obsidian samples.
