GTAF装置的获取系统以Acqiris公司生产的DC271A型FlashADC数字采集卡为基础,通过对40路BaF2探测器的全脉冲波形进行数字化采集,来实现数据的获取和在线实验的实时监控。图1为FlashADC获取到的γ射线和α射线的脉冲波形。图2为60Co与本底和不同幅度阈值下60Co的能谱图。图1γ射线(a)和α射线(b)的脉冲波形图2 60Co与本底的能谱图(a)和不同幅度阈值下60Co的能谱图(b)
The acquisition system of GTAF device is based on DC271A FlashADC digital acquisition card produced by Acqiris Company. Through digital acquisition of full pulse waveform of 40-channel BaF2 detector, data acquisition and real-time monitoring of online experiment are realized. Fig.1 shows the pulse waveforms of γ-rays and α-rays obtained by FlashADC. Figure 2 shows the energy spectrum of 60Co at 60Co with background and different amplitude thresholds.
