Ground-based gamma-ray astronomy has had a major breakthrough with the impressive results obtained using systems of imaging atmospheric Cherenkov telescopes. huge potential in astrophysics, particle physics and cosmology. CTA is an international initiative to build next generation instrument, factor 5-10 improvement sensitivity 100 GeV 10 TeV range extension energies well below above TeV. will consist two arrays (one north, one south) for full sky coverage be operated as open observatory....
We introduce a Xilinx RF System-on-Chip (RFSoC)-based qubit controller (called the Quantum Instrumentation Control Kit, or QICK for short), which supports direct synthesis of control pulses with carrier frequencies up to 6 GHz. The can multiple qubits other quantum devices. consists digital board hosting an RFSoC field-programmable gate array, custom firmware, and software optional companion custom-designed analog front-end board. characterize performance system as well its latency,...
Abstract This paper reports the design of a biosensor for sensitive, low-cost measurement lead in drinking water. The uses genetically-modified strain Escherichia coli , which serves as both signal amplifier and reporter water, measured via colour change. We developed PlomBOX platform to image this change we demonstrate its capability detect concentrations low World Health Organisation upper limit water 10 ppb. Our approach does not require expensive infrastructure or expert operators,...

Abstract The Q and U Bolometric Interferometer for Cosmology (QUBIC) is a ground-based experiment that aims to detect B-mode polarization anisotropies [1] in the CMB at angular scales around ℓ ≃100 recombination peak. Systematic errors make observations of B modes millimetre wavelengths very challenging QUBIC mitigates these problems somewhat complementary way other existing or planned experiments using novel technique bolometric interferometry. This takes advantage sensitivity an imager...
Bolometric interferometry is a novel technique that has the ability to perform spectral imaging. A bolometric interferometer observes sky in wide frequency band and can reconstruct maps several sub-bands within physical post-processing of data. This provides powerful method discriminate between cosmic microwave background (CMB) astrophysical foregrounds. In this paper, methodology illustrated with examples based on Q \& U Interferometer for Cosmology (QUBIC) which ground-based instrument...

Dark matter is thought to make up most of the density Universe, yet its true nature remains uncertain. Among dark theories, Weakly Interacting Massive Particles (WIMPs) are a prominent candidate for because they can reproduce observed abundance in universe. There various methods searching WIMPs, one which indirect detection, involves looking Standard Model particles produced by decay or self-annihilation particles. Within mass range GeV PeV particle, this type search be conducted detecting...
