The high-luminosity upgrade of the LHC (HL-LHC) imposes new requirements on the detectors. With the availability of highly resistive silicon in commercial CMOS processes, there are ongoing efforts to build depleted monolithic active pixel sensors (DMAPS) for high energy particle detectors. TJ-MonoPix is a prototype of such a pixel sensor in 180 nm TowerJazz technology. It is designed for usage in high-radiation environments such as the HL-LHC. The pixels with a small collection electrode design and pixel pitch of 36 um * 40 um are read out using a column-drain readout architecture.
In this talk, results from measurements with radioactive sources and in test beams will be presented. Furthermore, an overview of the ongoing work towards a future chip in this CMOS technology will be shown.
