DAQ systems
FELIX is one of the main components of the new ATLAS TDAQ architecture. This DAQ system will be installed in all the ATLAS sub-detectors in Run 4.
At Nikhef, a setup has been assembled in lab N221 with the purpose of training before petal arrival. In this setup, shown below, Phase-I FELIX (FLX-712) is used. Due to the lack of petals at the time, the sensor is an old barrel module with one ABC chip and one HCC chip, but no sensing material and no AMAC chip (there is a wire bond in its place to provide power). The VLDB+ with the Nikhef adapter board substitutes the EoS board, since the module has no AMAC chip, there is no external connection between the VLDB+ and the Nikhef adapter board, but whenever we use a module with it, we will need to connect them through a mini-HDMI cable. The lpGBT on the VLDB+ is not efused.
For more information about this training setup, you can contact Andrea García Alonso ([[1]]).
