Development of a phoswich endcap
The signals from the two detectors are separated by the electronic chain
The energy signal of the slower detector (LaCl3) is gated with region B
Development of a phoswich endcap
The detector response to high energy pprotons (120-180 MeV, has then be analyzed at the The Svedberg laboratory in Upspala
