The charge collection is measured with sensors exposed to fluences of up to $8 \\times 10^{15}~1~\\mathrm{\\,Me\\kern -0.1em V}~ \\mathrm{ \\,n_{eq}}~{\\mathrm{ \\,cm}}^{-2}$, as well as with nonirradiated prototypes. The results are discussed, including the influence of different levels of irradiation and bias voltage on the charge collection properties.
