An antineutron detectors calibration method for p → n charge-exchange differential cross-section measurement

Calibration procedures for charge-coupled device x-ray detectors

Calibration procedures are described for use with electronic x-ray detectors, with an emphasis on detectors based on fiber-optically coupled charge-coupled devices. Methods are detailed for removing spurious events, pixel pedestals, dark-current, spatial distortion, and intensity response variations for both small-angle and wide-angle applications. The accuracy of the calibration procedures is ...

Integral cross section measurement of the 12C(n,p)12B reaction

The integral cross section of the 12C(n, p)12B reaction was measured at the neutron time of flight facility n_TOF at CERN, from the reaction threshold at 13.6 MeV up to 10 GeV, by means of the combined activation and a time-offlight technique. The integral result is expressed as the number of 12B nuclei produced per single pulse of the neutron beam. A simple integral expression is given for cal...

p-air cross-section measurement at 1018.5 eV

The interaction cross-section is one of the fundamental properties of any elementary particle. For decades, only accelerator measurements of the particle cross-sections were available. Crosssection measurements at higher and higher energy become possible as more and more powerful accelerators are introduced. However, cosmic rays not only provide a constant flux of ultra highenergy particles, bu...

Surrogate Measurement of the 238Pu(n,f) Cross Section

The neutron-induced fission cross section of 238 Pu was determined using the surrogate ratio method. The (n,f) cross section over an equivalent neutron energy range 5–20 MeV was deduced from inelastic α-induced fission reactions on 239 Pu, with 235 U(α, α f) and 236 U(α, α f) used as references. These reference reactions reflect 234 U(n,f) and 235 U(n,f) yields, respectively. The deduced 238 Pu...
