	High sensitivity and precision are two of the most important properties of the electron beam position processors. They are crucial when measuring the orbit of the first turn, of the first few turns and of a stored beam with a partial or a single bunch filling pattern. Up to now, the orbit of the first turn has been measured on the base of a raw ADC data processing. In parallel to the processing path that uses digital down conversion for calculating the turn-by-turn data, the new Libera Brilliance⁺ instrument also comprises an advanced solution. A large ADC buffer for raw data analysis (~8 ms) is combined with the new time-domain processing, that returns precise turn-by-turn data. The article presents this new functionality of the instrument and illustrates it with measurement results from the KEK Photon Factory storage ring.

The APS has the largest installed base of closed-loop photon beam position monitors of any facility in the world, however many portions of the orbit control systems use aging and near-obsolete components. Substantial improvements in beam stability are planned as part of the on-going APS upgrade project. Among the planned improvements is a replacement of the present real-time feedback system using modern technology to increase the sample rate from 1.5 kHz to near 20 kHz. Because of this, new data acquisition options are being explored to support existing and new types of x-ray beam position monitors.
