	For successful commissioning and effective operation of the projected NSLS-II Booster, a set of beam diagnostic instruments has been designed. Fluorescent screens are used for the Booster commissioning and troubleshooting. Closed orbit is measured using electrostatic BPMs with turn-by-turn capability. The circulating current and beam lifetime are measured using a DC current transformer. The fill pattern is monitored by a fast current transformer. Visible synchrotron radiation is registered for observation of the beam image. Betatron tunes are measured using two pairs of striplines, the first pair is for beam excitation and the second one – for beam response measurement. Design and performance of the Booster beam instrumentation are described.

	To suppress the transverse instability, which is the main reason of beam current limitation at the VEPP-4M electron-positron collider, a digital bunch-by-bunch feedback system has been developed, installed and commissioned. The real-time data processing is performed by a special code running in an FPGA module. This provides high efficiency and flexibility of the system. During the system commissioning, a 3-times increase of the beam current injected into VEPP-4M was reached. The system design and data processing algorithms are described, the commissioning results are presented.

To suppress the transverse instability, which is the main reason of beam current limitation at the VEPP-4M electron-positron collider, a digital bunch-by-bunch feedback system has been developed, installed and commissioned. The real-time data processing is performed by a special code running in an FPGA module. This provides high efficiency and flexibility of the system. During the system commissioning, a 3-times increase of the beam current injected into VEPP-4M was reached.
