Measurement of the 35Cl(n, p)35S cross-section at the CERN n$$\_$$TOF facility from subthermal energy to 120 keV

Marco Antonio Martínez-Cañadas, P. Torres-Sánchez, J. Praena, I. Porras et autres

Abstract The 35 Cl( n , p ) 35 S reaction plays a key role in neutron dosimetry for Boron Neutron Capture Therapy, in the synthesis of the isotope 36 S, whose astrophysical origin remains unresolved, and in the design of next-generation …

Measurement of the 235U(n,f) cross section relative to the 10B(n,α) reaction with Micromegas detectors at the CERN n_TOF facility: First results

V. Michalopoulou, Μ. Diakaki, R. Vlastou, M. Kokkoris et autres

Neutron cross section measurements are often made relative to a neutron cross section standard. Thus, the accuracy of the neutron standards determines the best possible accuracy of the neutron measurements. The 235U(n,f) cross section is widely used as reference, while it is …

The Second Beam-Line and Experimental Area at n_TOF: A New Opportunity for Challenging Neutron Measurements at CERN

N. Colonna, Frank Gunsing, Enrico Chiaveri

Since 2001, a wealth of neutron capture and neutron-induced fission reactions has been measured at n_TOF, providing an important contribution to a wide variety of research fields. The experimental activity is driven mostly by two motivations: on the one hand, capture reactions …

Au197(n,gamma) cross section in the unresolved resonance region

C.M. Lederer, N. Colonna, C. Domingo‐Pardo, F. Gunsing et autres

The cross section of the reaction Au-197(n,gamma) was measured with the time-of-flight technique at the n_TOF (neutron time-of-flight) facility in the unresolved resonance region between 5 and 400 keV using a pair of C6D6 (where D denotes H-2) liquid scintillators for the …

Collimation for the LHC high intensity beams

O. Aberle, R. Aßmann, J. P. Bacher, V. Baglin et autres

The unprecedented design intensities of the LHC require several important advances in beam collimation. With its more than 100 collimators, acting on various planes and beams, the LHC collimation system is the biggest and most performing such system ever designed and constructed. …

The Study of a European Neutrino Factory Complex

D. Küchler, Chris Densham, A. Riche, A. Verdier et autres

The Neutrino Factory is a new concept for an accelerator that produces a high-intensity, high-energy beam of electron and muon neutrinos - the ultimate tool for neutrino oscillation studies and the only machine conceived up today that could help detect CP violation …

The Quadrupole Resonator: Construction, RF System Field Calculations and First Applications

Enrico Chiaveri, J. M. Tessier, E. Häbel, E. Mahner

The quadrupole resonator allows measurement of the RF properties of superconducting (sc) films deposited on disk-shaped metallic substrates. We describe the construction of the apparatus, the brazing and electron-beam welding procedures, the arrangements for compensating mechanical tolerances of samples and for assuring …

Superconducting, hydroformed, niobium sputter coated copper cavities at 1.5 GHz

D. Bloess, S. Cantacuzène, C. Hauviller, P. Bosland et autres

Results from RF tests of five-cell niobium sputter coated cavities are presented.Accelerating gradients of 13 MV/m at low field Q-values of 1010 have been obtained.Experimental data on the decrease of the Q-value with accelerating gradient are explained in a model, in which …
