Abstract

In 1994, the HERA electron-proton collider delivered an integrated luminosity of 6.1 pb^-1 to the ZEUS and H1 experiments each, about a factor of six more than in the previous year. The peak luminosity reached 4.7×10³⁰ cm^-2 s^-1 corresponding to 31% of the design value. This paper reviews the present performance limitations of HERA concerning luminosity operation and the plans for future improvements. After successful commissioning of the spin rotator in 1994 (65% longitudinal polarisation was achieved) the HERMES experiment has been installed during the winter shutdown and will start taking data this year. Further plans concern machine modifications for the installation of the HERA-B internal target experiment in the proton ring (study of CP violation)
