摘要: 中国科学院兰州近代物理研究所实验冷却储存环CSRe上的肖特基谐振腔的数据获取远控系统已搭建完成。该系统为核素质量与寿命测量平台的重要组成部分。其主要包含了两个构建在图形化界面上的数据获取控制程序和数据监测程序。该系统提供了多种功能,以快捷地辅助调整实验设置。系统充分利用了频谱仪及数据记录仪的自身功能,并借助独立触发系统与远程电源开关,补足了成品数据记录仪的硬件缺失,得以成功实现自动获取大数据量数据文件的设计目标。除满足了核素质量与寿命的测量需求之外,该系统也可用于其他以CSRe上肖特基谐振腔为测量设备的实验。Abstract: A remote control system of data acquisition for the Schottky resonator at Experimental Cooler Storage Ring(CSRe) in Lanzhou has been assembled as a part of the experimental platform for nuclear mass and lifetime measurements. It is the combination of a data acquisition program and a data monitor program, both of which are exhibited in graphical user interface(GUI). It provides a number of key features to assist the users for adjusting the acquisition settings according to the experimental requirements. It is also characterized by the full utilization of a spectrum analyzer and an IQ recorder. The automatic acquisition of data files in both large size and large amount can be realized with the supplementation of an independent trigger system and a remote button pusher to overcome the intrinsic defect of the IQ recorder. It fulfills the requirements by the nuclear mass and lifetime measurements as well as other beam experiments using the Schottky resonator as the main detector at the CSRe.

Figure 3. (color online) Control flow of the DAQ system. The program is executed in two threads. The modules for the interface are deployed in the main GUI thread, e.g. the judgments presented by rhombuses, the parameters setting presented by trapezoid. The processing modules, which are presented by rectangles, occupy the other DAQ thread to run the particular operations as well as the main thread to update the GUI elements showing the devices’ statuses.
Figure 4. (color online) The structure of a processing module is set in two threads. The signal from one thread will be sent instantaneously to the accompanied slot function in the other thread, which shares the same color with the signal, once the particular operation is finished. Then the slot function is called to update the GUI elements. Being executed in different threads avoids interruption between operations.
Figure 7. (color online) The structure of the button pusher. It is fixed between two handlers of the IQ recorder with a steel bar. One step motor is controlled by the ULN2003A driver board through the program on a raspberry pi to manipulate the motion of PVC cam component, which consists of an eccentric gear and a pushing rod. An additional power supply is used for the step motor.
Figure 8. (color online) The GUI of the button pusher with two display modes. The left is the normal mode, which includes two operations, turning on and turning off the power button of the IQ recorder. The right is the debug mode, which only appears after pressing a special hotkey and is used for calibrating the position of the rod.

It is the combination of a data acquisition program and a data monitor program, both of which are exhibited in graphical user interface(GUI). It provides a number of key features to assist the users for adjusting the acquisition settings according to the experimental requirements. It is also characterized by the full utilization of a spectrum analyzer and an IQ recorder. The automatic acquisition of data files in both large size and large amount can be realized with the supplementation of an independent trigger system and a remote button pusher to overcome the intrinsic defect of the IQ recorder. It fulfills the requirements by the nuclear mass and lifetime measurements as well as other beam experiments using the Schottky resonator as the main detector at the CSRe.
