Abstract

The MiniCactus sensors are demonstrator sensors designed in LFoundry LF15A 150 nm technology, intended to study the performance of non amplified High Voltage High Resistivity CMOS sensors for measurement of time of arrival of charged particles. This paper presents the context, design features and some of the first test-beam results obtained with the latest MiniCactus sensor version, MiniCactus V2. With a 175 micron thick sensor biased at -350 V, we have obtained a 60 ps time resolution on Minimum Ionizing Particles detected with a 500 micron by 500 micron pixel.
