Abstract = {{The solar wind is a highly turbulent medium, with a high level of field
   fluctuations throughout a broad range of scales. These include an
   inertial range where a turbulent cascade is assumed to be active. The
   solar wind cascade shows intermittency, which however may depend on the
   wind conditions. Recent observations have shown that ion-scale magnetic
   turbulence is almost self-similar, rather than intermittent. A similar
   result was observed for the high resolution measurements of proton
   density provided by the spacecraft Spektr-R. Intermittency may be
   interpreted as the result of the multifractal properties of the
   turbulent cascade. In this perspective, this paper is devoted to the
   description of the multifractal properties of the high resolution
   density measurements. In particular, we have used the standard
   coarse-graining technique to evaluate the generalized dimensions D-i,
   and from these the multifractal spectrum f(alpha), in two ranges of
   scale. A fit with the p-model for intermittency provided a quantitative
   measure of multifractality. Such indicator was then compared with
   alternative measures: the width of the multifractal spectrum, the peak
   of the kurtosis, and its scaling exponent. The results indicate that the
   small-scale fluctuations are multifractal, and suggest that different
   measures of intermittency are required to fully understand the small
   scale cascade. (C) 2017 COS PAR. Published by Elsevier Ltd. All rights
