The Compressed Baryonic Matter experiment (CBM) operating at high heavy-ion interaction rates of up to 10 MHz excludes conventional, latency-limited trigger architectures. Instead, CBM opted for a trigger-less streaming readout. To be able to operate the experiment at highest interaction rates, despite beam intensity fluctuations introduced by the slow extraction of the SIS 100 synchrotron, a time-based throttling mechanism is investigated. To achieve a high number of complete readout events, different throttling strategies are compared and the throttling algorithms and parameters are optimized.

CBM实验中无触发流式DAQ系统的节流策略与优化

在高达10 MHz的高重离子相互作用速率下运行的压缩重子物质实验（CBM）不包括传统的，受时延限制的触发体系结构。相反，CBM选择了无触发流式读取。为了能够以最高的交互速率进行实验，尽管SIS 100同步加速器的缓慢提取引起了光束强度的波动，但仍研究了基于时间的节流机制。为了获得大量的完整读出事件，比较了不同的节流策略，并对节流算法和参数进行了优化。
