Description
The IceCube Neutrino Observatory consists of two detector components: a cubic-kilometer in-ice neutrino detector and the IceTop surface array for high-energy cosmic rays. The proposed next-generation neutrino observatory, IceCube-Gen2, will increase the in-ice instrumented volume and add an additional in-ice radio detector for high-energy neutrinos. Furthermore, it will feature an entirely new surface array comprising approximately 160 surface stations covering $8\,$km$^2$, each equipped with eight scintillators for charged particle detection and three antennas for cosmic ray radio emission to enhance the physics reach. The surface radio readout of each station will receive triggers not only from local coincidences of the scintillators, but also from signals in other IceCube and IceCube-Gen2 detectors, requiring sufficient buffer depth of several seconds.
To achieve this buffer time, while aiming at $40\,$W electrical power budget per station, an Adaptive Readout for GSps Operation (ARGO) board is developed, which uses a multi-FPGA approach with LPDDR5 memory for radio buffering. Radio front-end and scintillator readout are realized with optional daughter boards to provide an experiment-agnostic mainboard that could also be used in other air-shower experiments.
In this contribution we will present the concept of the ARGO board and its current development status.
