The PiXeL detector (PXL) of the STAR experiment at RHIC is the first application of the state-of-the-art thin Monolithic Active Pixel Sensors (MAPS) technology in a collider environment. Designed to extend the STAR measurement capabilities in the heavy flavor domain, it took data in Au+Au collisions, p+p and p+Au collisions at $\sqrt{s_{NN}}=$200 GeV at RHIC, during the period 2014-2016.
The PXL detector is based on 50 μm-thin MAPS sensors with a pitch of 20.7 μm. Each sensor includes an array of nearly 1 million pixels, read out in rolling shutter mode in 185.6 μs. The 170 mW/cm2 power dissipation allows for air cooling and contributes to reduce the global material budget to 0.4% radiation length on the innermost layer. Detector performance and lessons learned from construction and operations will be presented in this talk.
Following the successful experience in STAR, the next-generation MAPS sensor will be used to upgrade the ALICE Inner Tracking System (ITS) at LHC. Compared to the STAR PXL detector, the integration time for the future ALICE ITS Upgrade has been reduced by more than a factor of 10, and down to
