High resolution RPC's for large TOF systems

Mostrar otras versiones (1)

Here we report on a particular type of RPC that presents up to 99% efficiency for minimum ionizing particles and a very good time resolution, below 50 ps s for the most optimized construction. Our 9 cm2 cells, made with glass and metal electrodes that form accurately spaced gaps of a few hundred mic...

Sumario:Here we report on a particular type of RPC that presents up to 99% efficiency for minimum ionizing particles and a very good time resolution, below 50 ps s for the most optimized construction. Our 9 cm2 cells, made with glass and metal electrodes that form accurately spaced gaps of a few hundred micrometers, are operated at atmospheric pressure in non-flammable gases and can be economically produced in large quantities, opening perspectives for the construction of large area time of flight systems.
