Objectif Research has been conducted towards the development of orrays of detectors for the observation of high energy gamma-rays produced in tagged photon induced nuclear reactions.Initial work was directed towards investigating possible materials for use in detecting high energy gamma-rays. However, it was latter decided to develop a combined pion proton detector (PIP). The detector comprises a Delta E layer and 4 E layers. The Delta E layer is made up of 4 1 mm sheets of plastic scintillator mounted vertically and viewed by fantail light guides at each end. Vertical position measurements of entrant particles are made by recording time differences from the signals observed at each end. The 4 E layers are made of 19 substantial blocks with thicknesses up to 17.5 cm each. A total thickness of 68 cm is achieved which is capable of stopping 180 MeV plons and 400 MeV protons. Horizontal position measurements are again achieved using time difference signals from each end of the blocks.The detector has been tested using a large neutron time of flight array and signals are compared to simulated data. Results are encouraging and it can be concluded that PIP is virtually complete and works well.A prototype was made available on 14/10/92 Champ scientifique natural sciencesphysical sciencestheoretical physicsparticle physicsphotons Programme(s) FP1-STIMULATION 1C - Plan (EEC) to stimulate European scientific and technical cooperation and interchange, 1985-1988 Thème(s) Data not available Appel à propositions Data not available Régime de financement CSC - Cost-sharing contracts Coordinateur University of Edinburgh Contribution de l’UE Aucune donnée Adresse Old College South Bridge EH1 1HN Edinburgh Royaume-Uni Voir sur la carte Coût total Aucune donnée Participants (1) Trier par ordre alphabétique Trier par contribution de l’UE Tout développer Tout réduire JOHANNES GUTENBERG UNIVERSITAET MAINZ Allemagne Contribution de l’UE Aucune donnée Adresse Staudinger Weg 7 55099 MAINZ Voir sur la carte Coût total Aucune donnée
