“…This technology has been successfully tested [28,29] and is being used in the framework of other projects [30]. Experimental tests performed with a single MRPC with an active area of 1.5×1.2 m 2 have shown 90% efficiency on the whole surface (limited by the pick-up electrode, which covers 90% of the detector active area), and about 300 ps time resolution.…”

The Search for Hidden Particles (SHiP) Collaboration has proposed a general-purpose experimental facility operating in beam-dump mode at the CERN SPS accelerator to search for light, feebly interacting particles. In the baseline configuration, the SHiP experiment incorporates two complementary detectors. The upstream detector is designed for recoil signatures of light dark matter (LDM) scattering and for neutrino physics, in particular with tau neutrinos. It consists of a spectrometer magnet housing a layered detector system with high-density LDM/neutrino target plates, emulsion-film technology and electronic high-precision tracking. The total detector target mass amounts to about eight tonnes. The downstream detector system aims at measuring visible decays of feebly interacting particles to both fully reconstructed final states and to partially reconstructed final states with neutrinos, in a nearly background-free environment. The detector consists of a 50 m long decay volume under vacuum followed by a spectrometer and particle identification system with a rectangular acceptance of 5 m in width and 10 m in height. Using the high-intensity beam of 400 GeV protons, the experiment aims at profiting from the 4 × 10 19 protons per year that are currently unexploited at the SPS, over a period of 5-10 years. This allows probing dark photons, dark scalars and pseudo-scalars, and heavy neutral leptons with GeV-scale masses at sensitivities that largely exceed those of existing and projected experiments. The sensitivity to light dark matter reaches well below the dark matter relic density limits in the range from a few MeV/c 2 up to 200 MeV/c 2 , and it will be possible to study tau neutrino interactions with unprecedented statistics. This paper describes the SHiP baseline experiment setup and the detector systems with performance results from prototypes in test beams. The expected detector performance from simulation is summarised at the end.

“…At the University of Santiago de Compostela (Spain), a medium‐size tRPC detector (1.2 × 1.5 m 2 ) with a space and time resolution of σ x , y ∼3 cm and σ t ∼300 ps, respectively, has been installed circa 2014 as part of the Trasgo Project (Belver et al., 2010; Blanco et al., 2014). It is named TRAGALDABAS (TRAsGo for the AnaLysis of the nuclear matter Decay, the Atmosphere, the earth B‐Field And the Solar activity), and it has been designed and built at LabCAF in collaboration with LIP (e.g., Abreu et al., 2018).…”

A high time resolution 2 m 2 tracking detector, based on timing Resistive Plate Chamber (tRPC) cells, has been installed at the Faculty of Physics of the University of Santiago de Compostela (Spain) in order to improve our understanding of the cosmic rays arriving at the Earth's surface. Following a short commissioning of the detector, a study of the atmospheric temperature effect of the secondary cosmic ray component was carried out. To take into account this effect, temperature coefficients, W T (h), were obtained from cosmic ray data using a method based on Principal Component Analysis (PCA). The results obtained show good agreement with the theoretical expectation. The method successfully removes the correlation present between the different atmospheric layers, which would be dominant otherwise. We briefly describe the initial calibration and pressure correction procedures, essential to isolate the temperature effect. Overall, the measured cosmic ray rate displays the expected anticorrelation with the effective atmospheric temperature, through the coefficient α T = −0.279±0.051%/K. Rates follow the seasonal variations, and unusual short-term events are clearly identified too.

“…Nowadays, three detectors are already operational and two more are under construction. In this document, a detector of the Trasgo family, TRISTAN, is presented [5]. The main goal is to study different local effects on the secondary cosmic ray flux measured at Earth's surface.…”
