Description
Positron annihilation (PA) techniques became, by now, routinely used
nuclear techniques with applications which range from structural
investigations of materials to biological samples and medical applications in
PET. As at present, both PA spectroscopy and PET could profit from an
improvement in fast coincidence technique, it was investigated how far
could a fully digitized positron lifetime spectrometer ( with full event storage
capability for the simultaneous recording of time and energy information of
the gamma rays) offer advantages over a conventional setup employing fast
analog nuclear electronics. The additional information allows off-line analysis
which could be particularly useful in separating various annihilation
channels, like positronium contribution, recently recognized to offer a new
window of observation not only in PA spectroscopy but in PET applications as
well.
