A triggerless DAQ for the Electron Ion Collider

The Electron-Ion Collider (EIC) is designed for a substantial progress in understanding the Quantum Chromo Dynamics (QCD). With an unprecedented luminosity and polarization of the beams, accelerating nuclei from H to U up to an energy in the center of mass of 140 GeV, EIC is the final tool to study parton distributions in nuclei, QCD at extreme parton density, spin and flavor structure of the nucleon and tests of the fundamental electro-weak symmetry. Given its wide program, the requirements posed to the experimental setups are highly challenging. In particular, the electron identification used to trigger the data acquisition, is one of the most important and crucial component of the whole experiment. We propose to study a triggerless data acquisition system for the EIC electromagnetic calorimeter, exploring the necessary algorithms to perform an on-line calibration/reconstruction and data filtering on a CPU-server and test the concept on an array of PbWO crystals read by SiPMs.
Streaming readout, requiring cutting-edge technology in data acquisition (front-end), data transmission/networking and CPU-based computing represents a breeding ground for tech development and transfer between academics and interested high-tech companies.
