The Compressed Baryonic Matter(CBM) experiment in the upcoming Facility for Antiproton and Ion Research(FAIR), designed to take data in nuclear collisions at very high interaction rates of up to 10 MHz, will employ a free-streaming data acquisition with self-triggered readout electronics, without any hardware trigger. A simulation framework with a realistic digitization of the detectors in the muon chamber (MuCh) subsystem in CBM has been developed to provide a realistic simulation of the time-stamped data stream. In this article, we describe the implementation of the free-streaming detector simulation and the basic data related effects on the detector with respect to the interaction rate.

即将到来的反质子和离子研究设施 (FAIR) 中的压缩重子物质 (CBM) 实验旨在以高达 10 MHz 的非常高的相互作用速率获取核碰撞中的数据，将采用自由流数据采集与自触发读出电子设备，无需任何硬件触发器。已经开发了一个模拟框架，该框架具有 CBM 中 μ 室 (MuCh) 子系统中探测器的真实数字化，以提供时间戳数据流的真实模拟。在本文中，我们描述了自由流检测器模拟的实现以及在交互率方面对检测器的基本数据相关影响。
