An integrated readout system for parallel-plate avalanche counter and multi-wire drift chamber at HIAF-HIRIBL

A newly developed, highly-integrated multi-channel front-end readout system – FEAM-256 – is presented for use with position-sensitive gaseous detectors, including parallel-plate avalanche counters (PPACs) and multi-wire drift chambers (MWDCs). The system’s position resolution was characterized using both an $\alpha$ source and cosmic-ray muons. Intrinsic position resolutions of 320 $\mu$m for the PPAC, and 424 $\mu$m for the MWDC were achieved. Designed specifically for integration into the data-acquisition infrastructure at the High-Rigidity radioactive Ion Beam Line (HIRIBL) of China’s High Intensity heavy-ion Accelerator Facility (HIAF), FEAM-256 enables seamless incorporation of PPAC and MWDC detectors into the HIRIBL experimental setup.
