CERN Microelectronics Group

The CERN Microelectronics Group is a specialized unit within CERN focused on the design, development, and support of radiation-tolerant integrated circuits, mixed-signal chips, and microelectronic systems for particle physics, space, and medical applications. It works at the intersection of accelerator experiments, detector development, and industrial microelectronics, providing ASIC design, technology evaluation, and qualification services for experiments at facilities such as the Large Hadron Collider, ISOLDE, AIDA and for missions coordinated by agencies like European Space Agency and National Aeronautics and Space Administration. The Group liaises with institutes, universities, and companies across Europe and worldwide to transfer technology from particle-physics requirements to commercial and scientific applications.

History

The Group traces its origins to CERN engineering efforts that supported early detector projects for the Proton Synchrotron and the Super Proton Synchrotron and later scaled with the construction of the Large Electron–Positron Collider and the Large Hadron Collider. Key historical collaborations connected CERN engineers with laboratories such as Brookhaven National Laboratory, Fermilab, DESY, LHCb, ATLAS, and CMS as detector complexity expanded. During upgrades linked to the High-Luminosity Large Hadron Collider project, the Group consolidated expertise in radiation-hard design methodologies developed alongside partners like STMicroelectronics, Infineon Technologies, and research centres such as Fraunhofer Society and CSEM. The Group has engaged with European programmes including Horizon 2020, EU Framework Programme, and technical infrastructures like ESRF and ILL to align microelectronics capabilities with experimental needs.

Research and Development

R&D efforts coordinate microelectronics design flows, layout techniques, and verification methodologies compatible with processes from foundries such as GlobalFoundries, TSMC, X-FAB, and ON Semiconductor. The Group drives studies on radiation effects referencing standards used by IEC and testing done at facilities like CERN Proton Synchrotron, Paul Scherrer Institute, and RAL Space. Projects explore mixed-signal architectures for front-end amplification, ADCs, DACs, phase-locked loops, and serializers compliant with readout systems used by ALICE, LHCb Upgrade, ATLAS IBL, and experiments at J-PARC. Algorithms and digital design methods integrate toolchains from Cadence Design Systems, Mentor Graphics, Synopsys, and verification supported by academic partners including EPFL, ETH Zurich, Imperial College London, and University of Oxford.

Detector Electronics and Applications

The Group supplies ASICs and front-end electronics tailored for silicon trackers, calorimetry, gas detectors, and time-of-flight systems used by experiments like ATLAS, CMS, ALICE, LHCb, NA62, and COMPASS. Beyond particle physics, applications extend to space instrumentation on missions coordinated with ESA and instrument builders at NASA Goddard Space Flight Center, radiation monitoring for satellites from Arianespace launches, and medical imaging devices developed with partners at Geneva University Hospitals and research teams at CERN Medical Applications. Integration work encompasses readout protocols and firmware compatible with platforms such as FPGA families from Xilinx and Intel (Altera), and data acquisition frameworks used by DATE and the International Data Centre.

Fabrication and Technology Platforms

The Group evaluates CMOS, SiGe, BiCMOS, SOI, and Silicon Photomultiplier integrated solutions, interfacing with fabrication fabs including TSMC, GlobalFoundries, X-FAB, ams AG, and radiation-hardened specialty houses. It maintains process design kits and qualification flows for deep-submicron nodes, collaborating on multi-project wafer runs coordinated with consortiums like Europractice and cleanroom facilities at institutions such as CERN MicroNanoLab and Microelectronics Research Center. Technology platforms address single-event effects, total ionizing dose, and displacement damage testing protocols used at irradiation sites including TRIUMF, GANIL, GSI Helmholtz Centre, and Los Alamos National Laboratory.

Collaborations and Partnerships

The Group maintains formal and informal partnerships with research institutes, universities, and industry: STMicroelectronics, Infineon Technologies, ams AG, GlobalFoundries, TSMC, X-FAB, Europractice, Fraunhofer Society, EPFL, ETH Zurich, Imperial College London, University of Oxford, University of Cambridge, CERN Accelerator Technology (AT), ATLAS Collaboration, CMS Collaboration, LHCb Collaboration, ALICE Collaboration, ESA, NASA, CINECA, and national laboratories including Brookhaven National Laboratory, Fermilab, DESY, Paul Scherrer Institute, and RAL. These partnerships support ASIC design, radiation testing, qualification, and technology transfer for scientific and commercial use.

Impact and Innovations

Innovations include radiation-tolerant ASIC architectures that enabled upgrades of pixel detectors in ATLAS and CMS, low-noise preamplifiers for calorimetry used by ALICE, and mixed-signal readout chips adopted in space instrumentation and medical imaging projects. Design techniques pioneered by the Group have influenced industrial practices at STMicroelectronics and ams AG and informed radiation-hardness assurance protocols referenced by ESA and national metrology institutes. The Group’s contributions have supported major discoveries at LHC experiments and fostered spin-off applications in space industry missions, medical imaging modalities, and radiation monitoring networks used in emergency response coordinated with agencies like IAEA.

Facilities and Resources

Resources include design suites with EDA tools from Cadence Design Systems, Synopsys, and Mentor Graphics, access to irradiation and test beams at facilities such as the CERN Proton Synchrotron, PSI, TRIUMF, and cleanroom/test infrastructures like the CERN MicroNanoLab. The Group manages multi-project wafer coordination through Europractice and maintains repositories of radiation qualification data used by collaborations across LHC experiments, space agencies such as ESA and NASA, and partner laboratories including Brookhaven National Laboratory and Fermilab.
