Positronium annihilation detection using Cherenkov radiation

In this project different methods for the detection of the positronium annihilation were tested. Testing was done only with cosmic rays because there was no positron source available at the time. Cosmic rays were detected using Cherenkov radiation in quartz crystal to which photomultiplier tubes were attached. The results showed that it should be possible to use Cherenkov radiation for positronium annihilation detection but there are still some improvements that should be made.
