The MARS15(2012) is the latest version of a multi-purpose Monte-Carlo code developed since 1974 for detailed simulation hadronic and electromagnetic cascades in an arbitrary 3-D geometry shielding, accelerator, detector spacecraft components with energy ranging from fraction electronvolt to 100 TeV.Driven by needs intensity frontier projects their Megawatt beams, e.g., ESS, FAIR Project X, has been recently substantially improved extended.These include inclusive exclusive particle event...
The linguistic privilege of native speakers in scientific communication, both oral and written, has been widely reported to influence researchers' publications careers beyond academia. I examine social structure communication the Science, Technology, Engineering Mathematics (STEM) fields through example big science attempt answer question why language injustice a less significant effect on non-native scientists engineers than philosophy scholars. do so by scrutinizing role signs...
The Fermilab Mu2e experiment seeks to measure the rare process of direct muon electron conversion in field a nucleus. Key design is system three superconducting solenoids; production solenoid (PS) which 1.8 m aperture axially graded with peak 5 T used focus secondary pions and muons from target located aperture; an “S shaped” transport (TS) selects transports subsequent towards stopping target; detector (DS) at upstream end transported target, spectrometer downstream accurately momentum...
The Fermilab Mu2e experiment seeks to measure the rare process of direct muon electron conversion in field a nucleus. magnet system for this is made three warm-bore solenoids: Production Solenoid (PS), Transport (TS), and Detector (DS). TS an “S-shaped” solenoid set between other bigger solenoids. has aperture 0.5 m 2.5 2.0 T. PS DS have, respectively 1.5 1.9 m, peak 4.6 T 2 In order meet specifications, starts inside ends DS. strong coupling with adjacent solenoids poses several challenges...
Novel beam-intercepting materials and targetry concepts are essential to improve the performance, reliability operation lifetimes of next generation multi-megawatt (multi-MW) accelerator target facilities. The components must sustain an order-of-magnitude increase in particle beam intensities beyond current state-of-the-art. With conventional already limiting scope experiments, it is crucial investigate novel materials, technologies that will satisfy requirements maximize physics benefits...
The Muon-to-Electron conversion experiment (Mu2e), under development at Fermilab, seeks to detect direct muon electron provide evidence for a process violating and lepton number conservation that cannot be explained by the Standard Model of particle physics. required magnetic field is produced series superconducting solenoids. This paper describes conceptual design 5 T, 4 m long solenoid cold mass with 1.67 bore emphasis on magnetic, radiation thermal analyses.
An observation of Charged Lepton Flavor Violation (CLFV) would be unambiguous evidence for physics beyond the Standard Model. The Mu2e and COMET experiments, under construction, are designed to push sensitivity CLFV in mu e conversion process unprecedented levels. Whether is observed or not, there a strong case made further improving sensitivity, examining on additional target materials. Mu2e-II proposed upgrade Mu2e, with at least an order magnitude rate over Mu2e. approach challenges this...
Experiments with the natural uranium target assembly "QUINTA" exposed to 4 and 8 GeV deuteron beams of Nuclotron accelerator at Joint Institute for Nuclear Research (Dubna) are analyzed. The reaction rates 27Al(n,y1)24Na, 27Al(n,y2)22Na 27Al(n,y3)7Be reactions effective threshold energies 5, 27, 119 MeV were measured both beam energies. average neutron fluxes between ends spectra (which 800 or 1000 deuterons) determined. evidence intensity shift higher increase energy from was found ratios...
Abstract A 232 Th activation sample was exposed directly to the spallation neutrons produced by 1GeV proton colliding with a lead target and other samples of 197 Au, 209 Bi, 59 Co, 115 In 181 Ta were irradiated moderated after passing through 6 cm paraffin. Different (n, γ) xn) reaction products in Th, Au Bi are analyzed gamma-ray spectrometry measure neutron fluence at positions samples. For this purpose histogram ‘flat’ spectrum averaged cross-sections over thirty given energy groups...
