STAR-DETECTOR FOR /$pi$ to the minus/ MESONS

Technical Report ·
OSTI ID:4197497
In contrast to many other particles, stopping pi /sup -/ mesons effectively produce stars with large energy release. These phenomena were utilized for selected detection of pi meson. The star-detector of pi mesons consists of a telescope of two scintillation counters set in coincidence. The first counter is an ordinary counter with 100% efficicncy for passing particles. The second counter works at a comparatively low voltage supply, hence it detects the large light impulses only. A typical range curve for 160 Mev pi /sup -/ mesons in carbon is given (W.D.M.)
