Abstract :
A novel digital RF-noise generator was used to excite the COSY-beam longitudinally at a certain harmonic of the revolution frequency. Rectangular shaped noise spectra with bandwidths of the order of 10 kHz and frequency resolution of about 6 Hz were used. Beam distributions were measured during shaping and after switching off the noise source in dependence of bandwidth and amplitude of the RF-noise
