Cible à hydrogène pour chambre BEBC

Track-sensitive target in BEBC being carried out rather independently with the aid of a betatron. Such targets combine the advantages of hydrogen and of heavy liquid bubble chambers. The tests have continued successfully with the target box suspended inside the bubble chamber. This sizeable "aquarium" made of Lexan, 2.4 m long, 1,4m wide and 0.8 m high will contain hydrogen or deuterium and be suspended in a neon-hydrogen mixture for high-energy neutrino or hadron experiments.
