  This article presents the readout electronics of a novel beam monitoring
system for ion research facility accelerator. The readout electronics are
divided into Front-end Card (FEC) and Readout Control Unit (RCU). FEC uses
Topmetal II minus to processes the energy of the hitting particles and convert
it into a voltage signal. The main function of RCU is to digitize the analog
output signal of FEC and format the raw data. On the other hand, the RCU also
processes the control commands from the host and distributes the commands
according to the mapping. The readout electronic has been characterized and
calibrated in the laboratory, and have been installed with the detector.
Implementation and testing of readout electronics have been discussed.
