The performance of the LHCb Muon system and its stability across full 2010 data taking with LHC running at ps = 7 TeV energy is studied. optimization detector setting time calibration performed first collisions delivered by described. Particle rates, measured for wide range luminosities beam operation conditions experienced during run, are compared values expected from simulation. space alignment detectors, chamber efficiency, resolution cluster size evaluated. found to be as specifications...
The existence of a light dark force mediator has been tested with the KLOE detector at DAPHNE. This particle, called U, is searched for using decay chain phi-->etaU, eta-->pi+pi-pi0, U-->e+e-. No evidence found in 1.5 fb-1 data. resulting exclusion plot covers mass range 5
The performance of the muon identification in LHCb is extracted from data using muons and hadrons produced J/ψ → μ+μ−, Λ0 pπ− D⋆+→π+D0(K−π+) decays. procedure based on pattern hits chambers. A momentum dependent binary requirement used to reduce probability be misidentified as level 1%, keeping efficiency range 95-98%. As further refinement, a likelihood built for non-muon hypotheses. Adding this that provides total at 93%, hadron misidentification probabilities are below 0.6%.
The energy of atmospheric neutrinos detected by MACRO was estimated using multiple Coulomb scattering upward throughgoing muons. This analysis allows a test neutrino oscillations, relying on the distortion muon distribution. These results have been combined with those coming from angular distribution only. Both analyses are independent flux normalization and provide strong evidence, above 4σ level, in favour oscillations.
The radiation used in hadrontherapy treatments interacts with the patient body producing secondary particles, either neutral or charged, that can be for dose and Bragg peak monitoring to provide a fast feedback on treatment plans. Recent results obtained from authors simplified setups (mono-energetic primary beams interacting homogeneous tissue-like target) have already indicated correlation exists between flux of these secondaries coming target (e.g. protons photons) position beam peak.

A novel radio guided surgery (RGS) technique for cerebral tumors using $\beta^{-}$ radiation is being developed. Checking the availability of a radio-tracer that can deliver emitter to tumor fundamental step in deployment such technique. This paper reports study uptake 90Y labeled (DOTATOC) meningioma and high grade glioma (HGG) feasibility RGS these cases.
Nuclear fragmentation measurements are necessary when using heavy-ion beams in hadrontherapy to predict the effects of ion nuclear interactions within human body. Moreover, they also fundamental validate and improve Monte Carlo codes for their use planning tumor treatments. Nowadays, a very limited set carbon cross sections being measured, particular, our knowledge, no double-differential at intermediate energies available literature. In this work, we have measured angular distributions...
The background induced by the high penetration power of radiation is main limiting factor current radio-guided surgery (RGS). To partially mitigate it, a RGS with β(+)-emitting radio-tracers has been suggested in literature. Here we propose use β(-)-emitting and β(-) probes discuss advantage this method respect to previously explored ones: electron low allows for simple versatile could extend tumours which originating from nearby healthy tissue makes less effective. We developed probe...
We have studied the phi->a_0(980) gamma process with KLOE detector at Frascati phi-factory DAPhNE by detecting phi->eta pi^0 decays in final states eta->gamma and eta->pi^+ pi^- pi^0. measured branching ratios for both states: Br(phi->eta gamma)=(7.01 +/- 0.10 0.20)x10^-5 (7.12 0.13 0.22)x10^-5 respectively. also extracted a_0(980) mass its couplings to eta pi^0, K^+ K^-, phi meson from fit of invariant distributions using different phenomenological models.
Organic scintillators are often chosen as radiation detectors for their fast decay time and low Z, while inorganic ones used when high light yields required. In this paper we show that a para-terphenyl based detector has blend of properties the two categories can be optimal energy position measurements low-energy charged particles. Using 0.1% diphenylbutadiene doped samples measured attenuation length λ = 4.73 ±0.06 mm, quenching factor α particles Q <sub...
In particle therapy, the uncertainty of delivered range during patient irradiation limits optimization treatment planning. Therefore, an in vivo verification device is required, not only to improve plan robustness, but also detect significant interfractional morphological changes itself. this article, effective and robust analysis regions with a discrepancy proposed. This study relies on by means in-beam Positron Emission Tomography (PET) was carried out INSIDE system installed at National...
Different therapies are adopted for the treatment of deep seated tumours in combination or as an alternative to surgical removal chemotherapy: radiotherapy with photons (RT), particle therapy (PT) protons even heavier ions like 12C, now available clinical centres. In addition these irradiation modalities, use Very High Energy Electron (VHEE) beams (100-200 MeV) has been suggested past, but diffusion that technique was delayed due needed space and budget, respect standard photon devices....
The treatment of deep-seated tumours with electrons very high energies (VHEE, 70–150 MeV) has already been explored in the past, suggesting that a dosimetric coverage comparable state-of-the-art proton (PT) or photon radiotherapy (RT) could be achieved large ( <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="m1"><mml:mo>></mml:mo></mml:math> 10) number fields and electron energy. technical economical challenges posed by deployment such beams centres, together expected small...
