Experimental Particle and Astro-Particle Physics Seminar

Stefanos Leontsinis (Universitaet Zuerich (CH))


Depleted monolithic active pixel sensors (DMAPS) have emerged as an attractive alternative to the established hybrid technology for high energy physics experiments due to their low material, low cost and reduced production complexity. Intensive R&D in recent years has resulted in several DMAPS development lines that provide fast charge collection and high radiation tolerance by exploiting modern CMOS technologies.

TJ-Monopix is a small collection electrode, full-scale DMAPS prototype for high radiation environments such as the HL-LHC. It is manufactured in a modified 180 nm CMOS imaging process and features a fast, standalone “column-drain” readout architecture. Small pixel size (33x33 μm2) is combined with low noise (<10 e-) and low analog power consumption (1μW/pixel) due to the very small sensor capacitance. This talk will cover design aspects and challenges in the development of TJ-Monopix as well as laboratory and test-beam measurement results that demonstrate detection efficiency up to 97% after irradiation to 10^15 neq/cm2 non Ionizing energy loss (NIEL) fluence.
