论文摘要
AIDA-2020触发逻辑单元（TLU）已设计为灵活且易于配置的单元，可为测试梁中使用的设备提供触发和控制信号，并将其与光束望远镜集成在一起。 TLU（V1E）的最新迭代已在AIDA-2020项目中重新设计，以与光束设施中使用的硬件集成。与TLU的配置和通信是通过以太网执行的。它可以用作独立单元，也可以作为EUDAQ2数据采集框架的一部分部署，该框架可以连接到广泛的LHC读数系统。 TLU可以以1 MHz的持续颗粒速率运行，并且瞬时速率高达20 MHz。在当前的固件迭代中，该设备可以以1.5 ns的分辨率来戳记传入信号。 TLU的硬件，固件和软件设计是可以自由访问的，并且受益于经验丰富的用户的持续投入和升级。 TLU单元已经成功部署在Cern和Desy的光束线中。
The AIDA-2020 Trigger Logic Unit (TLU) has been designed to be a flexible and easily configurable unit to provide trigger and control signals to devices employed during test beams, integrating them with the beam telescope. The most recent iteration of the TLU (v1E) has been re-designed within the AIDA-2020 project to integrate with hardware used in beam facilities. Configuration and communication with the TLU are performed over Ethernet. It can be employed as a stand-alone unit or be deployed as part of the EUDAQ2 data acquisition framework, which allows it to connect to a wide range of LHC readout systems. The TLU can operate with a sustained particle rate of 1 MHz and with instantaneous rates up to 20 MHz. In the current firmware iteration, the unit can time-stamp incoming signals with a resolution of 1.5 ns. The hardware, firmware and software designs of the TLU are freely accessible and benefit from constant inputs and upgrades from experienced users. TLU units have already been deployed successfully in beam lines at CERN and DESY.
