NorCC: Student/YR seminar

Tuesday 7 Feb 2023, 12:00 → 13:00 Europe/Zurich

Eli Baverfjord Rye (University of Oslo (NO)), Heidi Sandaker (University of Oslo (NO))

NorCC wants to give young researchers and students the opportunity to present their work to the Norwegian CERN community. This takes place the first Tuesday of every month at noon. A round of discussion will follow each presentation.

 

12:00 → 12:30 Readout Design for Pixel Sensors in a Calorimeter

The University of Bergen is currently involved in the design of the Forward Calorimeter (FoCal) in which two high-resolution pixel layers employing the ALICE PIxel Detectors (ALPIDEs) are an important part of the detector. Why do we use these digital sensors which only give hit or no-hit information in such a calorimeter? How are they used, and what are the challenges in reading out information from such a calorimeter? The readout is so much more than the choice of FPGA. The readout challenge starts already with how to receive a high-quality signal from the sensors in a radiation environment.

The presentation aims at giving the current status of the FoCal readout chain along with the decision-making methodology of the design.

Speaker: Tea Bodova (University of Bergen (NO))

12:30 → 13:00 Model independent search for Dark Matter using Machine Learning

I will present a model independent search for Dark Matter (DM) using Machine Learning (ML) techniques such as Boosted Decision Trees and Neural Networks using data from the ATLAS experiment at the LHC. I will in particular focus on the challenges when using ATLAS data in ML algorithms, possible mitigation of these and how they affect the sensitivity of a search for DM.

Speaker: Ruben Guevara (University of Oslo (NO))
