ATLAS pixel detector electronics and sensors

Abstract: The silicon pixel tracking system for the ATLAS experiment at the Large Hadron Collider is described and the performance requirements are summarized. Detailed descriptions of the pixel detector electronics and the silicon sensors are given. The design, fabrication, assembly and performance of the pixel detector modules are presented. Data obtained from test beams as well as studies using cosmic rays are also discussed.

“…The FE-I4 pixel array geometry is derived from that of the ATLAS pixel detector FE-I3 readout chip [6], wherein pixels are arranged in column pairs and power is segregated on vertical bands alternating between analog and digital. However, the readout architecture of FE-I4 is very different [7].…”

“…The limitations of the current ATLAS pixel Front-End FE-I3 [2] -in particular for what concerns radiation hardness and its ability to cope with high hit rates-have been realized a few years ago [3] and have led to the development of a new IC series in a smaller feature size, the FE-I4. With respect to previous Front-End generations, the FE-I4 shows an increased tolerance to radiation which mainly comes from using only the thinner gate oxide transistors which are offered in the 130 nm CMOS process.…”
