| Popis: | 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. |
