First measurements are presented of the diffractive cross section σep→eXY at centre-of-mass energies √ s of 225 GeV and 252 GeV, together with a new measurement at √ s of 319 GeV using data taken with the H1 detector. The measured FLD is compared with leading twist predictions based on diffractive parton densities extracted in NLO QCD fits to previous measurements.
