Description of laboratory and equipment

Laboratory for characterisation of photodetectors is founded with the aim to measure all relevant parameters of various photodetectors, with emphasis on new generation of single photon detectors. It is equiped with computer controlled temperature chamber, 6485 Keithley picoampermeter, Keithley 6487 voltage source/picometer, 2000 Keithley multimeter, CAEN N478 programmable source, CAEN silicon multiplier package. Recently, the lab has been upgraded with two CCD camers with partially overlaped fields of view (for CTA/LST consortium).

Particle and astroparticle physics (ASTROHEP)

Description of research in a 1-year term

Activities are planned to develop the theoretical and experimental aspects of the search for leptoquarks at the LHC. Likewise, we will be involved in the analysis of data obtained during the CMS Run3 period that began in 2022 and continued in 2023, 2024, 2025. It is also planned to continue work on the analysis of the production of a pair of Higgs bosons, and as a novelty study the possibility of measuring the production event of the heavy W_R boson whose existence is predicted by theories outside the Standard Model of elementary particles. Equally, we will continue with the activities in the HGCAL project, especially on testing the new generation of ASIC chips for the electronics installed on the detector itself, and on the design of the ASIC concentrator chips.

In addition to the CMS activities, activities on the collection and analysis of MAGIC telescope data are also planned. Work is planned to upgrade the software for the daily data quality check of the MAGIC telescope and to check the reliability of the operation of the new trigger of the MAGIC telescope system. Equally, it is expected to continue work on the analysis of high-energy gamma data collected by MAGIC observing pulsars (Crab, Geminga, Dragonfly). Our group is working on the design and construction of the Large Size Telescope (LST) CTA observatory protype and is responsible for the design, construction and commissioning of the LST telescope precision tracking and pointing correction system.
