Operation with multiple beams stored on different orbits in storage rings as well as beam dynamics studies requires accurate and stable Beam Position Monitor (BPM) measurements for each individual bunch. Analog BPM systems are usually optimized for measuring the closed orbit, i.e. averaging over all buckets and many turns. Therefore no information about the position of individual bunches are supplied. The new bunch resolved BPM electronic, currently under development at HZB, is based on the analysis of RF-signals delivered by a set of four stripline / pick-up electrodes in each beam position monitor. It has a high spatial resolution over a wide range of bunch currents. Using the four well matched (phase and amplitude) bunch induced RF-signals in combination with a low jitter master clock and commercial data acquisition cards allow beam position measurements on a bunch to bunch basis with micrometer resolution. Experimental results obtained at BESSY II and MLS demonstrates the achieved performance of the setup and will be discussed in detail.

The use of the Metrology Light Source (MLS), the electron storage ring of the Physikalisch-Technische Bundesanstalt (PTB, the German national metrology institute) as a primary radiation source standard requires the accurate measurement of all storage ring parameters needed for the calculation of the spectral radiant intensity of the synchrotron radiation. Therefore, instrumentation has been installed in the MLS for the measurement of, e.g., the electron beam energy, the electron beam current or the electron beam size that outperforms that usually installed in electron storage rings used as a common synchrotron radiation source. We report on the status and improvements in the storage ring parameter measurement.
