Abstract Despite the impressive progress achieved both by X-ray and gamma-ray observatories in last few decades, energy range between ∼ 200 keV 50 MeV remains poorly explored. COMPTEL , on-board Compton Gamma-Ray Observatory ( CGRO 1991-2000), opened band as a new window to astronomy, performing first all-sky survey from 0.75 30 MeV. More than 20 years after de-orbit of no successor mission is yet operating. Over past many concepts have been proposed, for exploring different configurations...
We report spectral and imaging performance of a pixelated CdZnTe detector custom designed for the \emph{MeVCube} project: small Compton telescope on CubeSat platform. is expected to cover energy range between $200\;\mathrm{keV}$ $4\;\mathrm{MeV}$, with comparable last generation larger satellites. In order achieve this goal, an resolution few percent in full width at half maximum (FWHM) $3$-D spatial millimeters individual detectors are needed. The severe power constraints present satellites...
The High Energy cosmic-Radiation Detection (HERD) facility has been proposed as one of the main scientific payloads on-board China Space Station. HERD is expected to be installed around 2027 and operate for at least 10 years. major goals mission are study cosmic rays' energy spectra composition up PeV range, indirect search dark matter particles via annihilation/decay, observation high-energy gamma-ray sky above $\sim 100\,\mathrm{MeV}$. To accomplish broad case, designed a large acceptance...
Over the past two decades, both X-ray and gamma-ray astronomy have experienced great progress. However, region of electromagnetic spectrum around ∼1 MeV is not so thoroughly explored. Future medium-sized telescopes will fill this gap in observations. As timescale for development launch a medium-class mission ∼10 years, with substantial costs, we propose different approach immediate future. In paper, evaluate viability much smaller cheaper detector: nano-satellite Compton telescope, based on...

HERD is scheduled to be installed around 2027 and operate for at least 10 years. Its scientific goals are study cosmic ray spectrum composition up PeV energy range, indirect dark matter detection, all-sky gamma-ray observation above 100 MeV. features a novel design in order optimize its acceptance per weight, with central 3D imaging calorimeter...
Compactness, robustness and low-voltage operation are some of the characteristics that make silicon photomultipliers (SiPMs) attractive for space applications. Signals recorded by SiPMs on board satellites must be processed digitized minimizing size, cost power consumption electronics. The BETA ASIC is a fully programmable chip designed to amplify, shape digitize signal up 64 channels, with only $\sim$1 mW/channel. Thanks its dual path gain, capable resolving single photoelectrons SNR$>$5,...
The High Energy cosmic-Radiation Detection (HERD) facility has been proposed as one of several space astronomy payloads onboard the China Space Station (CSS). HERD will address major problems in fundamental physics and astrophysics, including cosmic ray (CR) direct measurements up to PeV energies, dark matter searches, a gamma-ray survey above 0.1 GeV. consists five sub-detectors, 3D imaging calorimeter (CALO) with two independent readout systems, based on image intensified CMOS (IsCMOS)...
Despite the impressive progresses achieved both by X-ray and gamma-ray observatories in last decades, energy range between $\sim 200\,\mathrm{keV}$ 50\,\mathrm{MeV}$ remains poorly explored. COMPTEL, on-board CGRO (1991-2000), was telescope to accomplish a complete survey of MeV-sky with relatively modest sensitivity. Missions like AMEGO have been proposed for future, order fill this gap observation; however, time-scale development launch is about 10 years. On shorter time-scale, different...
Despite the great success achieved by X-ray and gamma-ray observatories in last two decades, energy range between few hundreds keV MeVs remains poorly explored. COMPTEL, on board CGRO (1991- 2000), was telescope to explore MeV domain, with a modest sensitivity. Many missions, like AMEGO, HERMES ETCC have been proposed, order fill this gap observations. However, time-scale for development launch of such big missions is around 10 years. Looking at scenario, nano-satellite Compton telescope,...
Connecting to theos, the greek term theoria means large and complete vision of truth that contains all events; this is way in wich Aristotle ricreated historic background development philosophy. My pourpose examine a known argument about existence gods order qualify the eminence wisdom as theoria, i. e. an exaustive view different beings speak them. The hypothesis god’s overlook kind logical close paradox it works only banning freedom comes from because was fighted by gods. problem, rised...
