Performance and Quality Control of a Radiation-Hard 12-bit 40 MSPS ADC for the ATLAS Liquid Argon Calorimeter Trigger Readout Electronics Phase-I Upgrade at the LHC

A radiation-hard quad-channel 12-bit 40 MSPS pipeline analog-to-digital converter (ADC) has been designed for the trigger readout electronics Phase-I upgrade of the ATLAS Liquid Argon calorimeter, at the CERN Large Hadron Collider. The final version of the custom design, fabricated in a commercial 130 nm CMOS process, is presented and found to meet the system requirements for analog performance and radiation tolerance. The procedure for quality control of 17200 ADCs is described and the results are presented.

A Prototype PCI-based Data Acquisition System for Cosmic Ray Detection Below 10^18 eV

A prototype flash analog-to-digital readout system for cosmic ray detection at energies below 10^18 eV has been designed and tested at Columbia University Nevis Laboratories. The electronics consist of an FADC module that digitizes 16 photomultipliers at 40 MHz with 14-bit dynamic range. The module is read out to a PC (running Linux) through a PCI interface. Taking advantage of the large bandwidth provided by the PCI bus, we have implemented a software-based data acquisition system. This note describes the software and electronics, as well as preliminary tests carried out using a prototype FADC module.
