Using these beams, the maximum of the dose is released to the tumor tissues at the end of the beam range. In this process, nevertheless, fragmentation of both projectile and target nuclei can occur in the nuclear interactions of the beam with the patient tissues and, as showed in recent studies, needs to be carefully taken into account in the delivered dose calculation. Nuclear fragmentation is also extremely relevant for space radioprotection studies, when the exposition of sensors and human crews to solar and galactic particle flows have to be minimized. The goal of the FOOT (FragmentatiOn Of Target) experiment is to estimate target and beam fragmentation performing cross section measurements (with respect to the kinetic energy and direction) with a precision of the order of 5% in the energy range of interest for hadrontherapy (protons in the energy range of 70-230 MeV or ion beams with energy up to 400 MeV/u) and space radioprotection (ion beams with energy up to 800 MeV/u) in order to provide new data for medical physicists, radio-biologists and to improve not only the new generation of oncological Treatment Planning Systems but also the design of shielding elements for the future long duration space missions eventually with human crews. In this paper will be presented the project, the present status of the different detector sub-systems construction and the data-taking plans.

The analysis is based on a data sample corresponding to an integrated luminosity of 9.6/fb collected by an online event selection based on charged-particle tracks displaced from the proton-antiproton interaction point. The significance of the observed signal is 3.5 Gaussian sigmas. The mass of the observed state is found to be 5919.22 +- 0.84 MeV in agreement with similar findings in proton-proton collision experiments

We report the first observation of single-top-quark production in the s channel through the combination of the CDF and D0 measurements of the cross section in proton-antiproton collisions at a center-of-mass energy of 1.96 TeV. The data sets correspond to total integrated luminosities of up to 9.7 fb^{-1} per experiment and were collected during Run II (2001-2011) of the Tevatron collider.

We present measurements of the elliptic ($\mathrm{v}_2$), triangular ($\mathrm{v}_3$) and quadrangular ($\mathrm{v}_4$) anisotropic azimuthal flow over a wide range of pseudorapidities ($-3.5< \eta < 5$). The measurements are performed with Pb-Pb collisions at sqrtstextNN=2.76\sqrt{s_{\text{NN}}} = 2.76sqrtstextNN=2.76 TeV using the ALICE detector at the Large Hadron Collider (LHC). The flow harmonics are obtained using two- and four-particle correlations from nine different centrality intervals covering central to peripheral collisions. We find that the shape of mathrmvn(eta)\mathrm{v}_n(\eta)mathrmvn(eta) is largely independent of centrality for the flow harmonics n=2−4n=2-4n=2−4, however the higher harmonics fall off more steeply with increasing ∣eta∣|\eta|∣eta∣. We assess the validity of extended longitudinal scaling of mathrmv_2\mathrm{v}_2mathrmv_2 by comparing to lower energy measurements, and find that the higher harmonic flow coefficients are proportional to the charged particle densities at larger pseudorapidities. Finally, we compare our me...

Measurements of charged jet production as a function of centrality are presented for p-Pb collisions recorded at sqrtsrmNN=5.02\sqrt{s_{\rm NN}} = 5.02sqrtsrmNN=5.02 TeV with the ALICE detector. Centrality classes are determined via the energy deposit in neutron calorimeters at zero degree, close to the beam direction, to minimise dynamical biases of the selection. The corresponding number of participants or binary nucleon-nucleon collisions is determined based on the particle production in the Pb-going rapidity region. Jets have been reconstructed in the central rapidity region from charged particles with the anti-$k_{\rm T}$ algorithm for resolution parameters R=0.2R = 0.2R=0.2 and R=0.4R = 0.4R=0.4 in the transverse momentum range 20 to 120 GeV/$c$. The reconstructed jet momentum and yields have been corrected for detector effects and underlying-event background.

We study charged particle production (pT> 0.5 GeV/c, |eta| < 0.8) in proton-antiproton collisions at 300 GeV, 900 GeV, and 1.96 TeV. We use the direction of the charged particle with the largest transverse momentum in each event to define three regions of eta-phi space; "toward", "away", and "transverse". The average number and the average scalar pT sum of charged particles in the transverse region are sensitive to the modeling of the "underlying event". The transverse region is divided into a MAX and MIN transverse region, which helps separate the "hard component" (initial and final-state radiation) from the "beam-beam remnant" and multiple parton interaction components of the scattering. The center-of-mass energy dependence of the various components of the event are studied in detail. The data presented here can be used to constrain and improve QCD Monte Carlo models, resulting in more precise pre...

Both present and future upgraded elements have to satisfy predefined validation procedure generally performed in irradiation facilities. Now-days these tests and studies can be performed not only in facilities explicitly built for this mission, but with some wisdom, also in medical or biological research facilities when some minima requirements are satisfied. In this article will be shown the planification and realization of SiPM x-ray irradiations for TID studies and characterization realized in the Italian TIFPA-INFN Trento Center laboratory, using instruments originally realized for medical or biological irradiations. In detail will be described the minimum flexibility required by the x-ray irradiation set-up and by the dose measurement system in order to perform this double...

In this area particle physics sensors for medical or space applications can be tested using a proton beam with energy between 70 MeV and 230 MeV. This area is also specially suitable for education initiatives addressed to both students or general public because in this space all the elements of a complex test-beam facility are accessible to the visitors: beam transport magnets, beam monitor devices, dose measurement devices, DAQ systems, target experimental sensors and remote monitoring systems for sensors. In this publication will be presented a description of the Trento Proton Therapy Center accelerator, the experimental area and also the public success obtained there during the Trento Smart City Week 2019 initiative in September 2019.
