A high temperature superconducting demonstrator coil for ARCOS: a novel toroidal magnetic spectrometer for an astroparticle physics experiment in space

By measuring their trajectories in the presence of a magnetic field, a magnetic spectrometer determines the signed rigidity of charged particles. The toroidal magnet has a 2 m outer diameter, 2 m in height, and requires about 60 meters of ReBCO HTS tape. Although HTS magnets have many potential uses in space, including active magnetic shielding, we describe the construction of an HTS magnetic spectrometer with a toroidal magnet that has a bending strength of 3 T m.

Development of a Carbon-fiber reinforced polymer-based mechanics for embedding ALPIDE pixel sensors in the High-Energy Particle Detector space module onboard the CSES-02 satellite.

The mission CSES will fly into orbit satellites to investigate perturbations in the ionosphere, perhaps related to seismic events. The ALPIDE technologies were adapted to the use in space environments, requiring the mechanics to withstand a variety of industrial and seismic stresses, as well as their ability to dissipate the heat generated by ALPIDE activities. An extensive series of qualification tests, conducted according to the space register and providing an important argument for future space cosmic ray experiments using monolithic active pixel sensors.

Inflation, space-borne interferometers and the expansion history of the Universe

The spectral energy density of the relic gravitons below a fraction of the Hz signal may exceed the conventional estimate obtained under the assumption of radiation dominance throughout the entire expansion period, prior to the emergence of light nuclei. Hence, any limit on the spectral energy density of the relic gravitons in the mHz bandwagons is simultaneously restricting the expansion history and inflationary initial estimates.

Deep neural network techniques in the calibration of space-charge distortion fluctuations for the ALICE TPC

The Time Projection Chamber of the ALICE experiment at the CERN LHC was updated for Run 3 and Run 4. Continuous data processing in Pb-Pb collisions are possible thanks to Gas Electron Multiplier technology and a new readout scheme. A considerable number of ions generated in the multiplication zone is expected to penetrate the TPC drift volume and distort the uniform electric field that leads the electrons to the readout pads due to the absence of a gating grid system.
