The tiny energy and small cross-section, from the interaction of dark matter particle on the target, requires a low threshold and sufficient background rejection capability of the detector. The XENON experiment uses dual phase technology to detect scintillation and ionization simultaneously from an event in liquid xenon (LXe). The distinct ratio, be- tween scintillation and ionization, for nuclear recoil and electron recoil events provides excellent background rejection potential. The XENON detector is designed to have 3D position sensitivity down to mm scale, which provides additional event information for background rejection. Started in 2002, the XENON project made steady progress in the R&D phase during the past few years. Those include developing sensitive photon detectors in LXe, improving the energy resolution and LXe purity for detect- ing very low energy events.

    Using a Two-Phase Xenon Time Projection Chamber for Improved Background Rejection in Searches for Neutrinoless Double-Beta Decay

    Using a two-phase xenon time projection chamber for improved background rejection in searches for neutrinoless double-beta decay by Callan Jessiman A thesis submitted to the Faculty of Graduate and Postdoctoral Affairs in partial fulfilment of the requirements for the degree of Master of Science in Physics Department of Physics Carleton University Ottawa, Ontario January 2020 c 2020 Callan⃝ Jessiman Abstract The nature of the neutrino masses is an important open question in particle physics; neutrinos were conceived and implemented into the Standard Model as massless, and their masses, now known to be nonzero, represent an area of new physics. Essential to the investigation of this area are mechanisms by which one might measure these masses, including the hypothetical neutrinoless double-beta decay, which has a lifetime related to the neutrino masses. Experiments searching for this rare decay, such as EXO, are impacted heavily by sources of background radiation. Here, a prototype two-phase time projection chamber is described, having superior temporal resolution to the existing EXO architecture. A machine- learning analysis of data from this prototype is used for pulse-shape discrimination, which has the potential to significantly increase EXO's sensitivity; the preliminary efforts described here are able to reduce backgrounds by 94%, while rejecting only 21% of the signal. ii Acknowledgements First, and foremost, I express my gratitude towards my supervisor, David Sinclair, and my colleague Braeden Veenstra. The entire project was of David's devising, as was the leadership that saw it through. Meanwhile, getting the thing to actually work, and extracting results from it, was Braeden's task as much as it was mine.

Interpreting these atmospheric signals poses a new challenge to planetary science. In contrast to jovian-like atmospheres, whose bulk compositions consist of hydrogen and helium, terrestrial planet atmospheres are likely comprised of high mean molecular weight secondary atmospheres, which have gone through a high degree of evolution. For example, present-day Mars has a frozen surface with a thin tenuous atmosphere, but 4 billion years ago it may have been warmed by a thick greenhouse atmosphere. Several processes contribute to a planet’s atmospheric evolution: stellar evolution, geological processes, atmospheric escape, biology, etc. Each of these individual processes affects the planetary system as a whole and therefore they all must be considered in the modeling of terrestrial planets.

    Design and Construction of the Spirit Tpc

    DESIGN AND CONSTRUCTION OF THE SPIRIT TPC By Suwat Tangwancharoen A DISSERTATION Submitted to Michigan State University in partial fulfillment of the requirements for the degree of Physics-Doctor of Philosophy 2016 ABSTRACT DESIGN AND CONSTRUCTION OF THE SPIRIT TPC By Suwat Tangwancharoen The nuclear symmetry energy, the density dependent term of the nuclear equation of state (EOS), governs important properties of neutron stars and dense nuclear matter. At present, it is largely unconstrained in the supra-saturation density region. This dissertation concerns the design and construction of the SπRIT Time Projection Chamber (SπRIT TPC) at Michigan State University as part of an international collaborations to constrain the symmetry energy at supra-saturation density. The SπRIT TPC has been constructed during the dissertation and transported to Radioactive Isotope Beam Factory (RIBF) at RIKEN, Japan where it will be used in conjunction with the SAMURAI Spectrometer. The detector will measure yield ratios for pions and other light charged particles produced in central collisions of neutron-rich heavy ions such as 132Sn + 124Sn. The dissertation describes the design and solutions to the problem presented by the measurement. This also compares some of the initial fast measurement of the TPC to calculation of the performance characteristics. ACKNOWLEDGMENTS The design and construction of the SAMURAI Pion-Reconstruction and Ion Tracker Time Projection Chamber (SπRIT TPC) involved an international collaboration to study and constrain the symmetry energy term in the nuclear equation of state (EOS) at twice supra- saturation density. The TPC design and construction as well as many additional aspects of the project were supported financially by the U.S.

    The Electric Sun Hypothesis

    Basics of astrophysics revisited. II. Mass- luminosity- rotation relation for F, A, B, O and WR class stars Edgars Alksnis [email protected] Small volume statistics show, that luminosity of bright stars is proportional to their angular momentums of rotation when certain relation between stellar mass and stellar rotation speed is reached. Cause should be outside of standard stellar model. Concept allows strengthen hypotheses of 1) fast rotation of Wolf-Rayet stars and 2) low mass central black hole of the Milky Way. Keywords: mass-luminosity relation, stellar rotation, Wolf-Rayet stars, stellar angular momentum, Sagittarius A* mass, Sagittarius A* luminosity. In previous work (Alksnis, 2017) we have shown, that in slow rotating stars stellar luminosity is proportional to spin angular momentum of the star. This allows us to see, that there in fact are no stars outside of “main sequence” within stellar classes G, K and M. METHOD We have analyzed possible connection between stellar luminosity and stellar angular momentum in samples of most known F, A, B, O and WR class stars (tables 1-5). Stellar equatorial rotation speed (vsini) was used as main parameter of stellar rotation when possible. Several diverse data for one star were averaged. Zero stellar rotation speed was considered as an error and corresponding star has been not included in sample.

    DISSERTATION Titel der Dissertation A GEM based Time Projection Chamber prototype for the PANDA¯ experiment - Gas system development and forward tracking studies Verfasser Mag. rer. nat. Philipp Müllner angestrebter akademischer Grad Doktor der Naturwissenschaften (Dr. rer. nat.) Wien, 2012 Studienkennzahl lt. Studienblatt: A 091 411 Dissertationsgebiet lt. Studienblatt: Physik Betreuer: Doz. Dr. Johann Zmeskal 2 Abstract The PANDA¯ collaboration is building a state-of-the-art universal detector for strong interaction studies at the High Energy Storage Ring (HESR) at the new Facility for Antiproton and Ion Research (FAIR) at Darmstadt, Germany. The facility will provide a high intensity, cooled antiproton beam. Together with the advanced particle identification system of the PANDA¯ detector a wide experimental program ranging from QCD studies to funda- mental symmetry tests will be accessible. One of two options for the PANDA¯ central tracker was a Gas Electron Multiplier (GEM) based Time Projection Chamber (TPC). The low ma- terial budget GEM based TPC is an ideal device for 3-dimensional space tracking, which features fulfill the PANDA¯ tracking system requirements, e.g. high rate capability, continuous operation, high momentum resolution, high spatial resolution and full solid coverage. In the course of the detector developments for PANDA,¯ a large GEM- TPC prototype was build and tested at GSI (Darmstadt, Germany) by the GEM-TPC collaboration. Within the framework of this work, an overview of the prototype general design will be given. The main task of my thesis was the development of a closed gas supply system for the large GEM-TPC prototype. The detector requirements made it necessary to build it as closed circulation system with infrastructures for O2 and H2O measurement and purification as well as for precise pressure controlling inside the gas system.

As core-helium burning, hydrogen-free objects with huge mass-loss, they are likely the last observable stage before collapse and thus promising progenitor candidates for type Ib/c supernovae. Their strong mass-loss furthermore provides challenges and constraints to the theory of radiatively driven winds. Thus, the determination of the WC star parameters is of major importance for several astrophysical fields. With Gaia DR2, for the first time parallaxes for a large sample of Galactic WC stars are available, removing major uncertainties inherent to earlier studies. In this work, we re-examine a previously studied sample of WC stars to derive key properties of the Galactic WC population. All quantities depending on the distance are updated, while the underlying spectral analyzes remain untouched.
