CERN Accelerating science


Michael Bacak

I rejoined the CERN n_TOF facility after LS2 to support the currently ongoing commissioning of its novel 3rd generation spallation target as well as to work on two projects. The first project is a proof of principle measurement of inelastic neutron cross-sections employing Germanium detectors following a long lasting technological development on the cold pre-amplifiers in collaboration with Canberra. The second project aims to study the feasibility of a potential neutron-neutron scattering length measurement at n_TOF, using a combination of an active plastic scintillator target coupled with other detection systems in order to detect all ejectiles involved.

Mikko Barinoff

I recently started as a fellow in EP-CMX-DA, and I work with the phase-2 upgrade of the CMS tracker. My area of work is mechanical integration design, which includes managing the routing of power, cooling and data lines of the tracker, and designing various tools and fixtures for the assembly and installation process. This is already my third stint at CERN, as I was a technical student and a summer student before.

Naomi Benchaya

I am the assistant of Professor Samuel Ting, Spokesperson of the Alpha Magnetic Spectrometer (AMS), a particle detector located on the ISS which measures cosmic rays and searches for antimatter and dark matter. I am honored and excited to be a part of the AMS team and the wider CERN community and to witness from up close the collective efforts towards uncovering the mysteries of the Universe. Prior to joining CERN I worked in several assistant positions for the European Union, both at itse headquarters in Brussels and at the New York and Geneva Delegations.

Frank Browne

Recently I started as a Senior Applied Fellow at ISOLDE, a facility for the study of unstable nuclei at CERN. An objective of mine is the installation and operation of a gamma-ray detector array for measuring internal decays of fast-moving unstable nuclei. Using this device and the excellent beam properties at ISOLDE, I will investigate the structure of very unstable nuclei to shed light on the nature of in-medium nuclear interactions. Previously I worked at the RIBF, RIKEN in Japan, where I studied interplays of nuclear structure and reactions through very fast-moving beams of unstable nuclei.

Piotr Dorosz

I come from the beautiful city of Cracow located in the southern part of Poland. I obtained a PhD in electronics at my alma mater: AGH University of Science and Technology. Throughout my scientific career as an electronic engineer, I have been designing front-end electronics for photodetectors including Silicon Photomultiplier (biomedical and IT based hardware applications) and Multi-Anode Photomultiplier Tubes (LHCb RICH detector). I joined EP-ESE-ME group in September to work on the digital implementation flow of the MOSS Stitched Sensor which is a prototype design for the ALICE ITS upgrade.

Sean Freeman

I joined CERN in August as ISOLDE Physics Section Leader and Collaboration Spokesperson from the University of Manchester, where I was Head of the Department of Physics and Astronomy and worked closely with a UK funding agency as Chair of STFC Science Board. I’m looking forward to supporting the broad and world-leading science programme at ISOLDE, fostering the large ISOLDE user collaboration, and helping to develop the facility to increase both the capacity and capability for science which spans nuclear physics, condensed matter physics and fundamental interactions, all the way through to chemistry and life sciences. I moved my own research programme to CERN a few years ago and was part of the team that built the ISOLDE Solenoidal Spectrometer, a novel device for studying nuclear reactions which we are now using to better understand nuclear structure and nuclear astrophysics.

Saranya Ghosh

I am an experimental particle physicist working on the CMS experiment and I have joined CERN as a senior research fellow in August 2021. At CERN, I have joined the EP-CMG group. During my time as a fellow, I plan to work on the search for physics beyond the Standard Model based on displaced soft lepton signatures that are motivated by supersymmetry models along with dark matter scenarios. Alongside that, I plan to work on the upgrade of the CMS detector for LHC phase-2, specifically on the High Granularity Calorimeter (HGCAL) detector hardware and reconstruction.

Marta Krawczyk

I have joined the CMS experiment under Eva Sicking, responsible for silicon detector technology. My task is the investigation of the radiation hardness of the detectors, specifically electrical characterization, conceptualization, irradiation campaigns and quality control. The detectors are to be used in the CMS Endcap Calorimeter upgrade. Prior to CERN, I have worked in the industry as a technology developer for high frequency electronic assembly techniques. There I have designed, simulated, produced and characterized test packages made of semiconductors, ceramics, printed circuit boards and other materials

Ole Schmidt

I joined the EP-AIP-SDS team in July this year. Before coming to CERN, I completed my doctoral studies in Heidelberg where I already worked on the ALICE experiment, specifically on online reconstruction and calibration. As a fellow I am going to continue in this direction and engage in reconstruction and calibration of the Time Projection Chamber and the Transition Radiation Detector employing GPUs as hardware accelerators. In this field I hope to learn a lot from David Rohr and Ruben Shahoyan. Together with David I am also responsible for the physics data processing operation which involves training and assignment of shifts.

Franco Bandi.

I am an analog and mixed-signal designer. On September 2021, I joined the EP-ESE-ME team, which designs Application Specific Integrated Circuits (ASICs) for the experiments at CERN. Currently, the team is migrating from a 65nm to a 28nm CMOS technology, to provide the next generation of ASICs for the High Energy Physics (HEP) community. As a Fellow, I will design and characterize low-power, low-voltage, radiation hard circuit IP blocks in 28nm CMOS technology. The developed circuits will be a essential part of more complex mixed-signal ASICs. I will also disseminate the know-how learned to other designers in the HEP community.
