ANKE is a second-generation experimental facility at the internal beam of the accelerator COSY at the Forschungszentrum Juelich (Germany). It has recently (May 1998) been installed in the ring, commissioned, and immediately after this exploited for the first experiments. Using circulating beams of protons with energy between 1.0 and 2.3 GeV, sub- and near-threshold production of K{sup +} mesons in collision with carbon-strip targets has been investigated. The detection system of ANKE used for the first measurements is capable of detecting positively charged ejectiles in the momentum range between about 100 and 600 MeV/c. In particular, it has been optimized for K{sup +} identification in the presence of an intense background of protons and pions. The final results of the experiments (cross sections and momentum spectra) will be used to obtain more detailed information on the subthreshold production mechanism.
