New Beam Position Detectors for NA61/SHINE experiment

The NA61/SHINE experiment at the CERN SPS is undergoing a major upgrade during the CERN Long Shutdown 2 period (2019-2021). The upgrade is essential to fulfill the requirements of the new open charm and neutrino programs. In these programs the NA61/SHINE will operate with the data acquisition rate increased by a factor of 10, which requires an upgrade of current Beam Position Detectors (BPDs). New detectors should monitor beam particle positions with a frequency up to 10$^{5}$ Hz.This paper presents an overview of the new BPD design, as well as discusses current state of development and prototype production of BPD, including: mechanical design, front-end electronics design and integration with experiment’s data aquisition system.
