Nuclear electronics group in IMP is focused on researching and developing the instruments and the readoutsystems for the research of nuclear and particle physics, and the relevant interdisciplinary research. Some creativeworks have been done by the team in 2014.First, a front-end electronics (FEE) for a plastic scintillation array detector has been developed successfully,which has been used in a scientific satellite (engineering model) for space dark matter explore. There are 360channels included in the FEE, which can process the signals from dynodes of PMTs combined with the plasticscintillators in the detector. For each channel, the input dynamic range is from 120 fC to 12 pC, and the nonlinearityis better than 2%, the equivalent noise is less than 0.1 MIPs, and resolution is better than 0.8%. The dead timefor read out the data in FEE is less than 1.5 ms. Meanwhile, a data acquisition system (DAQ) employed for testperformance of the FEE in laboratory has been developed also.
