Please give a brief summary of your poster

The reduced cross sections for ep deep inelastic scattering have been
measured with the ZEUS detector at HERA at three different centre-of-mass
energies, 318, 251 and 225 GeV. From the cross sections, measured double
differentially in Bjorken x and the virtuality, Q2, the proton structure
functions F_L and F_2 have been extracted in the region
0.0005<x<0.007 and 20<Q2<130 GeV^2.
