Characterisation of a multi-anode ACHINOS sensor for Spherical Proportional Counters — •Itxaso Beatriz Antolín, Konstantinos Nikolopoulos, Ioannis Manthos, Isabella Oceano, and Theodoros Avgitas — University of Hamburg, Hamburg, Germany

The Spherical Proportional Counter (SPC) is a gaseous detector that combines intrinsic low capacitance with high gain, enabling energy detection thresholds down to the single ionization electron level. These features make the SPC a promising technology for searches for low-mass dark matter. In this talk the characterisation of a multi-anode ACHINOS sensor, consisting of 11 individually readout anodes, is presented. Moreover, the latest developments in SPC readout are discussed.
