	One of the most essential lattice function used for transverse beam dynamics studies of the storage rings is a beta function. It characterizes the linear properties of magnets layout and allows to optimize the compatibility of the model and the machine by reducing the beta-beating. Moreover, the calculation of other parameters like transverse beam emittance, dynamic aperture, energy spread and others, requires knowledge of the quantity of beta function along the ring. Various methods of measurement of this function used in Solaris will be presented.

	Solaris storage ring is a recently constructed and commissioned machine. At the beginning of storage ring operation the lifetime was very short mostly dominated by the ion trapping and residual gas scattering. After a 390 A·h of beam cleaning the measured total lifetime has reached 20 h for 100mA of a stored current. Since the main contribution to the total lifetime in the storage ring comes from single Coulomb and Touschek scattering the dependence of the residual gas pressure and the vertical aperture of storage ring is investigated. Moreover to improve the Touschek lifetime the 3^rd harmonic cavities were installed. Recently the cavities were tuned close to the resonance and the total lifetime increased significantly. This presentation will report on the lifetime measurements and calculations carried out for Solaris 1.5 GeV storage ring at different vacuum and RF conditions.

MOPAB096	Universal Digital Aggregator for in-Line Signal Processing	352
	M.P. Kopeć, Ł.J. Dudek, A. Kisiel, M.A. Knafel, A.I. Wawrzyniak, M. Zając Solaris National Synchrotron Radiation Centre, Jagiellonian University, Kraków, Poland
	Universal digital aggregator is a device for general signal processing with around 100kHz bandwidth. It contains of 4 inputs and 4 open-drain outputs - all of which are fully programmable. When the number of controlling digital signals exceeds the number of input ports of a device there is a need to either multiplex those signals or process them before the target device. The aggregator can be powered from the target device so no additional cabling is needed, especially considering its low power consumption. This straightforward, complex and portable device can be easily applied where PLC solutions are difficult to implement.

	The storage ring which is located in the National Synchrotron Radiation Center SOLARIS works under the TANGO control system. So far the correction of an electron beam orbit has been performed with an algorithm implemented in the Matlab Middle Layer (MML). To ensure consistency of the correction process with the entire control system, a new implementation of this algorithm has been developed. The algorithm of orbit correction based on SVD has been implemented as a TANGO Device, which is one of the fundamental blocks used in the Tango control system. The entire code has been written in the Python.
