Detection of the Diffuse Supernova Neutrino Background with JUNO

As an underground multi-purpose neutrino detector with 20 kton liquid scintillator, Jiangmen Underground Neutrino Observatory (JUNO) is competitive with and complementary to the water-Cherenkov detectors on the search for the diffuse supernova neutrino background (DSNB). Typical supernova models predict 2-4 events per year within the optimal observation window in the JUNO detector. The dominant background is from the neutral-current (NC) interaction of atmospheric neutrinos with 12C nuclei, which surpasses the DSNB by more than one order of magnitude. We evaluated the systematic uncertainty of NC background from the spread of a variety of data-driven models and further developed a method to determine NC background within 15\% with {\it{in}} {\it{situ}} measurements after ten years of running. Besides, the NC-like backgrounds can be effectively suppressed by the intrinsic pulse-shape discrimination (PSD) capabilities of liquid scintillators. In this talk, I will present in detail the improvements on NC background uncertainty evaluation, PSD discriminator development, and finally, the potential of DSNB sensitivity in JUNO

Radioactivity control strategy for the JUNO detector

602siopenJUNO is a massive liquid scintillator detector with a primary scientific goal of determining the neutrino mass ordering by studying the oscillated anti-neutrino flux coming from two nuclear power plants at 53 km distance. The expected signal anti-neutrino interaction rate is only 60 counts per day (cpd), therefore a careful control of the background sources due to radioactivity is critical. In particular, natural radioactivity present in all materials and in the environment represents a serious issue that could impair the sensitivity of the experiment if appropriate countermeasures were not foreseen. In this paper we discuss the background reduction strategies undertaken by the JUNO collaboration to reduce at minimum the impact of natural radioactivity. We describe our efforts for an optimized experimental design, a careful material screening and accurate detector production handling, and a constant control of the expected results through a meticulous Monte Carlo simulation program. We show that all these actions should allow us to keep the background count rate safely below the target value of 10 Hz (i.e. ∼1 cpd accidental background) in the default fiducial volume, above an energy threshold of 0.7 MeV.

Developement of a Free-Running Readout ASIC for the PANDA Micro Vertex Detector and Investigation of the Performance to Reconstruct Antiproton-Proton →Xi+ Xi-(1690)

The PANDA experiment is a multi-purpose particle detector, investigating hadron physics topics in the strange and charm quark mass regime. PANDA will measure antiproton-proton annihilation reactions at the FAIR complex, which is currently under construction. Caused by the initial reaction, signal and background events are similar to each other. Hence, self-triggering readout electronics is required throughout all sub-detectors. The innermost sub- detector, the Micro Vertex Detector, is based on silicon sensors with pixel and microstrip segmentation. This thesis describes the development of a readout solution (PASTA) for the microstrip sensors and the preparations for a characterization setup to perform laboratory measurements with this readout prototype. Furthermore, an exploratory study on the reconstructability of the reaction $\overline{p}p \rightarrow \overline{\Xi}^{+}\Xi^{-}(1690)$ with PANDA's software framework is presented

SQuBiC1: An integrated control chip for semiconductor qubits

The Central Institute for Electronic Systems at Forschungszentrum Jülich develops, designs and tests scalable solutions for the control and readout of qubits to be used in future quantum computers. The focus lies on highly integrated system-on-chip (SoC) solutions leveraging state-of-the-art commercial semiconductor technologies.We are working according to the V-model of engineering to approach system solutions in a top-down design and bottom-up implementation. As part of the bottom-up implementation, we designed and layouted a first test chip in a commercial 65nm CMOS process . The chip contains all infrastructure needed to control a GaAs semiconductor qubit. It features a DC-digital-to-analog converter (DC-DAC) that generates the tuning voltages in the range of 0V to +1V to bring the qubit into the operation point. The pulse DAC, running at 250MHz, generates pulses with ± 4mV amplitude to generate gate sequences for operating the qubit. In this presentation, we will describe the chip architecture in detail and show corresponding simulation results

SQuBiC1: An Integrated Control Chip for Semiconductor Spin Qubits

In most quantum experiments nowadays the control and readout electronics is placed at room temperature. The number of qubits which can be operated with this approach is severely limited by the number of interconnects and the wiring between the qubit operating temperature level and the room temperature level. At the Central Institute for Electronic Systems at the Forschungszentrum Jülich we develop and design scalable solutions for readout and control of qubits for future use in quantum computers. Our approach leverages the advances of state-of-the-art commercial CMOS technologies while operating at deep-cryogenic temperatures close to the actual qubit. We designed and layouted a first chip for concept proof in a commercial 65 nm CMOS process. This chip contains a DC-digital-to-analog converter (DC-DAC), a pulse digital-to-analog converter, a 500 MHz digitally controlled current starved ring oscillator and a 20 GHz LC-oscillator. The DC-DAC is operating in a voltage range between 0 V and 1 V. The pulse DAC operates at a sample rate of 250 MHz and generates pulses in a range of 8 mV. In this presentation the chip architecture will be discussed in detail and corresponding simulation results will be shown

Modeling and Simulation of Digital Phase-Locked Loop in Simulink

This paper presents a high-level model for a digital phase-locked loop implemented in Simulink. This modeling enables the flexible and fast estimation of the design behavior and parameters before transistor-level implementation. The design includes a digital controlled oscillator that is defined using a linear s-domain model. Furthermore, the design of a time-to-digital converter based on oversampling and noise shaping is introduced to increase the effective resolution of the block. The simulation results of locking process, stability and phase noise verify the functionality of the model
