Today, dark matter represents the first evidence for new physics beyond the Standard Model, which is extremely successful to explain all observed phenomena in experimental particle physics, including the recent discovery of the Higgs boson. Currently, DarkSide, a liquid argon-based direct dark matter search experiment, has world-leading sensitivity for light dark matter candidates. The detailed characterization of liquid argon response to nuclear recoils (possible signals from dark matter particles) at low energy is essential to extend the sensitivity to lighter dark matter particles.
This project involves research on different aspects of the liquid-argon Time Projection Chamber (TPC) including designing and building of TPC, handling cryogenic system, simulating detector response using GEANT4, data acquisition, and analysis to draw physics results. Within this project, the obtained results will be used to re-analyze available data from DarkSide-50 experiment, which could lead to the world best results for light dark matter search.
The position is available for up to four years and funded by a studentship of approx. 3500-4500 PLN per month, plus medical and social insurance benefits. The candidate is expected to have master degree in physics or astronomy at the starting date.
Note: This project is optionally available as a dual PhD program with Gran Sasso Science Institute (GSSI), leading to two PhD degrees (one in Poland and one in Italy); the successful candidate must satisfy PhD requirements of both CAMK PAN and GSSI. Long-term visits to GSSI will optionally be funded.

In rare event search experiments, such as dark matter searches and neutrinoless double beta decay searches, background event rates have to be suppressed below expected signal rates. In order to reach ultimate sensitivities for those searches, background contributions from detector components need to be suppressed. In this project, we focus on the photodetection part of detectors (silicon-based photodetector modules and light guides), which is a leading background contributor in both dark matter and neutrinoless double beta decay searches.
This project involves research on different aspects of the photodetector in cryogenic temperature including searching for radiopure components for the photo-detector and light guide, assaying materials, handling cryogenic system, and optimization of coupling between the photodetector and the light guide. This project also aims to design a photodetector module and to estimate sensitivities for future experiments.

Liquid argon based dark matter detectors currently taking data (DEAP-3600) or planned (DarkSide-20k, Argo) have a significant potential to discover Weakly Interacting Massive Particles (WIMPs) and will reach the ultimate sensitivity accessible to such searches. With silicon photomultipliers (SiPM), recently introduced novel light sensors to be used by the next round of experiments, pulse-shape discrimination (the key technique necessary to mitigate backgrounds in liquid argon), requires computational and experimental studies necessary to optimize it for better sensitivity to WIMPs.
This project includes testing of novel SiPM modules developed by the DarkSide collaboration, as well as the cutting-edge digital version of SiPMs, which is under development for future detectors at the Universite de Sherbrooke (Canada) and elsewhere.
Data from small and intermediate scale prototype detectors operated by the Global Argon Dark Matter Collaboration will be available for this analysis, with the goal of extracting important physics results with the optimized method.

Liquid argon based dark matter detectors currently taking data (DEAP-3600) or planned (DarkSide-20k, Argo) have a significant potential to discover Weakly Interacting Massive Particles (WIMPs) and will reach the ultimate sensitivity accessible to such searches. In such detectors, wavelength shifter (WLS) materials are used to convert argon scintillation light (at 128 nm) to visible wavelengths, which can be efficiently detected by standard sensors.
This project involves comparative study of the most commonly used WLS and its novel alternatives, and selecting the best candidate tailored for specific application in the planned experiments, which would lead to extending their physics reach. Another aspect of this study is the compatibility of such new materials with silicon photomultipliers (SiPM) used by DarkSide-20k, quantifying their impact on the sensitivity of future experiments, and optimizing the light collection with Monte Carlo simulations.
The scope of this work includes R&D shared with collaborating institutions in Poland, Canada and Italy, and possible participation in development and installation of SiPM and WLS for the DarkSide-20k veto at Laboratori Nazionali del Gran Sasso (Italy).

The VIRGO detector is a part of the gravitational wave detection network that includes LIGO and KAGRA. It has been involved in the breakthrough detections of gravitational waves from inspiralling compact object binaries. The project is part of the effort to improve the VIRGO sensitivity at low frequency.
The project aims at the construction of an infra-sound sensor working in the frequency range below 10 Hz. The sensor will be the basis for construction of a system to monitor the infra-sound field inside buildings in real time. The second part of the project is the construction of data acquisition system allowing to measure infra-sound from a network of 10-20 sensors and off-line analysis of infra-sound sources.

The purpose of the work is to develop a filter that allows increasing the signal-to-noise ratio of the signal from the optical detector. Knowing the shape of the response signal from the optical detector and the analog front end of the optical system, it is possible to design a matched filter to the response of the optical detector that will improve the signal from the detector.
