Description
Silicon Micro-strip Detector (SMD) has been widely used in detecting charged particles. Using SMD as detector, and to measure the Linear Energy Transfer (LET) generated by the ionizing radiation in manned spacecraft, a prototype of LET spectrometer is designed. This paper presents the design of the data acquisition (DAQ) software for the LET spectrometer. To read out and preliminarily analyze the data, the DAQ software is consist of three modules, which are readout and control module, data real-time imaging module, and offline data analysis module. Multiple data tests are included in the DAQ software as a result of reliability requirement of the data. The DAQ software realizes the dual communication interface through the Ethernet interface of the back-end electronics, which are used to summarize the data generated from the three detectors of the prototype in the experiment, and the USB interface of the front-end electronics for debugging a single detector. Qt is used as the development tool for Windows platform, because of its excellent reliability and maintainability. Its cross-platform-ability is also important to operate in other platforms. Due to the small amount of data and high demand of efficiency, it is appropriate to choose C + + as the programming language. In the tests, the DAQ software shows good performance and fits the needs of application.
