چکیده
Abstract A prototype of the CMOS pixel sensor named Supix -1 has been fabricated and tested in order to investigate feasibility a pixelated tracker for proposed Higgs factory, namely, Circular Electron-Positron Collider (CEPC). The sensor, taped out with 180 nm Image Sensor (CIS) process, consists nine different arrays varying pitches, diode sizes geometries study particle detection performance enlarged pixels. test was carried 55 Fe radioactive source. Two soft X-ray peaks observed were used calibrate charge voltage factor sensor. pixel-wise equivalent noise charge, collection efficiency signal-to-noise ratio evaluated. reconstruction method clustering pixels signal developed cluster-wise studied as well. results show that area large 21 × 84 μm have satisfactory level performance, meeting general requirements This contribution demonstrates using CIS technology, can be tracking upcoming collider detectors akin CEPC.

Active Pixel Sensor Architectures in Standard CMOS Technology for Charged-Particle Detection
The adoption of active pixel sensors (APS), based on an “active” read-out scheme implemented at the pixel level, has been recently proposed for charged-particle detection purposes [1, 2]. Very good performances have been obtained, in particular by exploiting some peculiar features of the actual fabrication technology (i.e., the presence of a relatively deep and low-doped epitaxial layer). In th...
