	The DAΦNE Beam Test Facility delivers electron and positron beam with a wide spread of parameters in charge, energy, transverse dimensions and time width. Thanks to the recent improvements of the diagnostics, all the beam parameters have been measured and optimized. In particular we report here some results on beam transverse size, divergence, and position stability for different energy and intensity configurations. After the upgrade of the electronic gun of the DAΦNE LINAC, the pulse time width and charge distribution have been also characterized.

	The DAΦNE Beam Test Facility (BTF) is operational in Frascati since 2003. In the last years the beam diagnostics tools have been completely renewed and the services for users have been largely improved. We describe here the new transverse beam diagnostics based on new GEM TPC detectors and Timepix/FitPix, the new BTF network layout, the renewed DAQ system including the BCM detectors, the data caching system based on MEMCached and the integration of the new sub-systems in the new data-logging. All other services, such as the environmental monitoring system, vacuum system, payload remote handling, and gas distribution have been also improved.

TUPWA056	New Gun Implementation and Performance of the DAΦNE LINAC	1546
	B. Buonomo, L.G. Foggetta, G. Piermarini INFN/LNF, Frascati (Roma), Italy
	A new electron gun system has been developed for DAΦNE LINAC, and put into operation since January 2014. Several elements of the system were upgraded, including a new grid pulser, an improved bias voltage system and a renewed cathode socket. The new LINAC gun has now a wider range of parameters, i.e. the emission pulse length spans from 1.4ns up to 40ns, while the better control of the grid and bias voltage allows a maximum peak current of 5A with a pulse repetition rate of 50 Hz. This paper describes the details of the pulser, the power supply, the socket, all the service components of the upgraded gun and its integration in the main LINAC control system. A report on the performance of the LINAC with the new gun will follow.

TUPWA057	DAΦNE LINAC: Beam Diagnostics and Outline of the Last Improvements	1549
	B. Buonomo, L.G. Foggetta INFN/LNF, Frascati (Roma), Italy
	The LINAC of the DAΦNE complex is in operation since 1996, both as injector of the e⁺ e⁻ phi-factory, and, since 2003, for the extraction of electron beam to the Beam Test Facility. In the last years, many improvements has been developed in different sub-systems of the LINAC, aiming at a wider, tunable range of beam parameters, in particular the pulse time width and the pulse charge. A long term measurement campaign has been recently started to characterize the LINAC performance after that many sub-systems has been overhauled and improved, starting from RF power (i.e. klystron substitution, modulator re-newing, RF driver layout, SLED tuning) as well as the timing system, magnets, cooling, vacuum, control system and energy/position diagnostics. This work reports the latest results on the optimization of the fully consolidated system.
