Radiation-Hard Opto-Link for the Atlas Pixel Detector
K.K. Gan, et al
TL;DR
This paper discusses the development and testing of radiation-hard optical links for the ATLAS pixel detector, including irradiation studies demonstrating their durability under high radiation levels.
Contribution
It introduces radiation-hard receiver and transmitter chips for the ATLAS pixel detector's optical links, with experimental results from irradiation tests showing their robustness.
Findings
Opto-boards function effectively after irradiation.
Radiation levels up to 33 Mrad do not impair performance.
The components meet the requirements for high-radiation environments.
Abstract
The on-detector optical link of the ATLAS pixel detector contains radiation-hard receiver chips to decode bi-phase marked signals received on PIN arrays and data transmitter chips to drive VCSEL arrays. The components are mounted on hybrid boards (opto-boards). We present results from the opto-boards and from irradiation studies with 24 GeV protons up to 33 Mrad (1.2 x 10^15 p/cm^2).
