Upgrade of the PreProcessor system for the ATLAS level-1 calorimeter trigger
The ATLAS Level-1 Calorimeter Trigger is a hardware-based pipelined system designed to identify high-PT objects in the ATLAS calorimeters within a fixed latency of 2.5 us. It consists of three subsystems: the PreProcessor which conditions and digitises analogue signals and two digital processors. Th...

| Summary: | The ATLAS Level-1 Calorimeter Trigger is a hardware-based pipelined system designed to identify high-PT objects in the ATLAS calorimeters within a fixed latency of 2.5 us. It consists of three subsystems: the PreProcessor which conditions and digitises analogue signals and two digital processors. The majority of the PreProcessor's tasks are performed on a dense Multi-Chip Module(MCM) consisting of FADCs, a time-adjustment and digital processing ASICs, and LVDS serialisers designed and implemented in ten year old technologies. An MCM substitute, based on today's components (dual channel FADCs and FPGA), is being developed to enhance the flexibility of the digital processing and to profit from state-of-the-art electronics. The development and first test results are presented. |
