Um estudo da física de sistemas multiplicadores subcríticos acionados por aceleradores
(Universidade Federal de Santa MariaCentro de Ciências Naturais e Exatas, 2008-01-30)
In this work were reviewed the operation principles of subcritical multiplying systems powered by accelerators (ADS) from the point of view of the neutron transport. To do this it was necessary to characterize theoretically ...
Produção de partículas secundárias em reações de “spallation” induzidas por prótons
(Universidade Estadual Paulista (Unesp), 2012)
Cosmic radiation has been identi ed as one of the main hazard to crew, aircraft and sensitive equipments involved in long-term missions and even high-altitude commercial ights. Generally, shields are used in spatial units ...
New high-sensitivity searches for neutrons converting into antineutrons and/or sterile neutrons at the HIBEAM/NNBAR experiment at the European Spallation Source
(IOP Publishing, 2021-07)
The violation of baryon number, is an essential ingredient for the preferential creation of matter over antimatter needed to account for the observed baryon asymmetry in the Universe. However, such a process has yet to be ...
