New pixel detector concept DuTiP for Belle II upgrade and the ILC with an SOI technology

2020 
Abstract Belle II detector upgrade is being discussed aiming to collect five times larger integrated luminosity of 250 ab − 1 . The beam background level is expected five times higher than current design, thus a new pixel vertex detector with faster readout should be developed. We have invented a new pixel detector concept DuTiP for the Belle II upgrade which can be also used for the International Linear Collider (ILC) with small modifications. To realize the DuTiP concept, an SOI technology is chosen as a baseline with a pixel size of 35 μ m × 35 μ m . The DuTiP concept and its application to a monolithic pixel detector in an SOI technology are explained.
