A central problem for the electron machines PETRA, HERA and DORIS is the strong current limitation due to multi-bunch instabilities. The design currents of these machines are a factor of twenty above threshold currents. For the proton machines the be

The most efficient method to damp multi-bunch oscillations in a storage ring is to install an active feedback loop. However, the technical problem of such a device is connected with the high bandwidth which is defined by the inverse of the time of fl

A new damping mechanism of multi-bunch oscillations in a storage ring with help of a narrow-band feedback system has been experimentally tested in PETRA. The oscillations of a multi-bunch filling were sucessfully damped. The bandwidth of the active l

During the last year the e-e+-storage ring DORIS was changed from a 2 × 3,5 GeV double ring with 2 × 480 bunches circulating to a single ring single bunch machine with a maximum energy of 2 × 5.1 GeV. The modifications in the magnet structure and

The shift in frequency of the fundamental m = 0 head tail mode in a storage ring can be calculated from the optics and the wake potentials. Such calculations have been performed for various beam pipe components in PETRA and are summarized here. Compa
