The new spectrometer ANKE has been put into operation at the accelerator CO
SY of the Forschungszentrum Julich. It enables the study of forward going e
jectiles from proton-induced reactions at internal targets in COSY. First m
easurements of the double differential cross sections for the subthreshold
K+-production in pA collisions have been performed at projectile energies a
s low as 1.0 GeV, i.e. 0.58 GeV below the free nucleon-nucleon threshold.
