The energy spectrum of cosmic rays beyond the turn-down around eV as measured with the surface detector of the Pierre Auger Observatory
The Pierre Auger Collaboration, P. Abreu, M. Aglietta +374
We present a measurement of the cosmic-ray spectrum above 100\,PeV using the part of the surface detector of the Pierre Auger Observatory that has a spacing of 750~m. An inflection…
H-diluted precursors for GaAs doping in chemical beam epitaxy
K. Ben Saddik, A. F. Braña, N. López +2
A wide range of n- and p-type doping levels in GaAs layers grown by chemical beam epitaxy is achieved using H-diluted DTBSi and CBr as gas precursors for Si and C. We s…
Measurement of the fluctuations in the number of muons in extensive air showers with the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Aab, P. Abreu +365
We present the first measurement of the fluctuations in the number of muons in extensive air showers produced by ultrahigh energy cosmic rays. We find that the measured fluctuation…
