Abstract Targeting a peak luminosity of 6 × 10 35 cm -2 s -1 , the Belle II experiment at SuperKEKB in Japan is considering an upgrade its interaction region. This involves vertex detector, which will be replaced by new fully pixelated detector (VTX). A monolithic CMOS pixel sensor named OBELIX (Optimized BELle pIXel) proposed to used VTX. Based on existing TJ-Monopix2 chip initially developed for ATLAS Inner Tracker (ITk) upgrade, designed 180 nm process with improved matrix and additional...
Abstract The Belle II collaboration has initiated a program to upgrade its detector in order address the challenges set by increase of SuperKEKB collider luminosity, targeting 6×10 35 cm 2 s -1 . A monolithic CMOS pixel sensor named OBELIX (Optimized BELle pIXel) is proposed equip 5 detection layers upgrading current vertex detector. Based on existing TJ-Monopix2, currently designed 180 nm process.
Monolithic pixel detectors combine readout electronics and sensor in a single entity of silicon, which simplifies the production procedure lowers material budget compared to conventional hybrid detector concepts. Benefiting from advances commercial CMOS processes towards large biasing voltage capabilities increasing availability high-resistivity substrates, depleted monolithic active sensors (DMAPS) can cope with high-rate high-radiation environments faced modern high-energy physics...
