Abstract: During luminosity operation of the HERA e-p collider, protons can be stored for more than 24 hours. Unpleasant proton backgrounds develop during long fills which have been traced to beam coasting outside the RF bucket. This causes a large problem for the data acquisition of the internalwire target experiment HERA-B.We will discuss the origin of coasting beam and various cures. The most successful method is to excite coasting beam particles near the vertical betatron tune using a broadband kicker which fires in the dump gap of the proton bunch train.
