Description

Supernova neutrinos can easily be detected by a spherical gaseous TPC detector measuring very low-energy nuclear recoils. The expected rates are quite large for a neutron-rich target since the neutrino-nucleus neutral current interaction yields a coherent contribution of all neutrons. As a matter of fact for a typical supernova about 1000 events are expected using a spherical detector of radius 4 m with Xe gas at a pressure 10 atm

Abstract (Russian)

Нейтрино суперновых могут быть легко зарегистрированы с помощью сферического газового детектора, измеряющего ядра отдачи с очень низкой энергией. Ожидаемые скорости счета довольно велики в случае избыточно-нейтронной мишени, поскольку взаимодействие нейтрального тока нейтрино-ядро обеспечивает когерентный вклад в образованные нейтроны. Фактически ожидается, что для типичной сверхновой около 1000 событий будет достаточно использования одного такого сферического детектора радиусом 4 м при давлении Хе около 10 атм
