Benefiting from the reconfigurable hardware structure and digital pulse processing technology RNIS shakes off the restrictions of cumbersome crates and miscellaneous modules. It retains all the advantages of conventional nuclear instruments and is more flexible and portable. RNIS is primarily composed of a field programmable hardware board and relevant t）C software. Separate analog channels are designed to provide different functions, such as am- plifiers, ADC, fast discriminators and Schmitt discriminators for diverse experimental purposes. The high-perfornmnce field programnmble gate array could complete high-precision time interval measurement, histogram accumulation, counting, and coincidence anticoincidence measurement. To illustrate tile prospects of RNIS, a series of applications to the experiments are described in this paper. The first, for which RNIS was originally developed, involves nuclear energy spectrum mea- surement with a scintillation detector and photonmltiplier. The second experiment applies RNIS to a G-M tube counting experiment, and in tile third, it is applied to a quantum comnnmication experiment tllrough reconfiguration.展开更多
