摘要：
A new facility for prompt gamma-ray activation analysis (PGAA) will be installed at the end of one of the cold neutron guides of the spallation neutron source, SINQ, at the PSI. One interesting feature of the proposed PGAA is the use of a neutron focusing lens which will permit two-dimensional scanning of samples and spectroscopy of isotopes having small capture cross sections. With some precautions, sensitivities on the order of a few ppm can be obtained for hydrogen.
