The silicon-strip vertex detector in the Belle II experiment is one of essential detectors to search for physics beyond the Standard Model. To read out all 223,744 readout strips of the double-sided silicon strip detectors in high beam background, 1748 APV25 chips are employed for the frontend electronics. Hence, flash analog-to-digital conversion with high-density inputs is required on the back-end electronics. We developed prototypes of the back-end electronics and successfully performed a full integration test at the DESY electron beam line. In this paper, we report on the development of the prototypes and results from the beam test.

Abstract
The silicon-strip vertex detector in the Belle II experiment is one of essential detectors to search for physics beyond the Standard Model. To read out all 223,744 readout strips of the double-sided silicon strip detectors in high beam background, 1748 APV25 chips are employed for the frontend electronics. Hence, flash analog-to-digital conversion with high-density inputs is required on the back-end electronics. We developed prototypes of the back-end electronics and successfully performed a full integration test at the DESY electron beam line. In this paper, we report on the development of the prototypes and results from the beam test.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
