Instrument control can improve measurement level of automation. In the actual control of the accelerator electron gun, we need to obtain a voltage with different amplitudes for the filament. Boost and voltage regulator modules should be used in the 220V AC input conditions. In order to adjust the filament voltage and stabilize the filament current more convenient, we developed a control software based on LabVIEW.

To solve the problem of spectrum acquisition in LIBS (Laser-Induced Breakdown Spectroscopy), a real-time data acquisition system was designed based on PSoC (Programmable System-On-Chip). First, the linear array CCD with electronic shutter function TCD1304DG has been used as detector .And then, the AD7621, a 16-bit analog-to-digital converter, was used to convert signal from the AFE (Analog Front End). After that, a high-integrated, low-power PSoC5LP was used as core controller, it works to complete the driver and data communication, including CCD , ADC, FIFO, the USB interface, etc. At last, a WIFI module has been added to the system for the convenience of users as well as follow-up research. The result through board-level testing indicates that the system in the spectrum acquisition is stable and accurate, and the indicators meet the LIBS project requirements.
