Description

The RD53 collaboration was founded to tackle the extraordinary challenges associated with the design of pixel readout chips for the innermost layers of particle trackers at future high energy physics experiments. Around 20 institutions are involved in the collaboration, with the support of both ATLAS and CMS experiments. 

The goals of the collaboration include the comprehensive understanding of radiation effects in the 65 nm technology, the development of tools and methodology to efficiently design large complex mixed signal chips and, ultimately, the development of a full sized readout chip featuring a 400x400 pixel array with 50 um pitch and capable to operate with serial powering.

In August 2017 the collaboration submitted RD53A, a large scale chip demonstrator, integrating a matrix of 400x192 pixels with design variations in the analog and digital pixel matrix for testing purposes.

The seminar will describe the chip architecture and the experimental results coming from the characterization of the RD53A prototypes.
