	The DAΦNE BTF (beam-test facility) can provide electrons and positrons, tuning at runtime different beam parameters: energy (from about 50 MeV up to 750 MeV for e^- and 540 MeV for e+), intensity (from single particle up to 10¹⁰/bunch) and pulse length (in the range 1.5-40 ns) up to 49 Hz, depending on the operations of the DAΦNE collider. The beam spot and divergence can be adjusted, down to sub-mm sizes and 2 mrad (downstream of the vacuum beam-pipe exit window), matching the user needs. We describe of the BTF beam transverse monitor systems based on FitPIX detectors, operating in bus synchronization mode externally timed to the BTF beam. We also describe our custom software allowing the acquisition and synchronization of the beam diagnostics with the users data, using TCP/IP calls to MEMCACHED. The performance of the system in a variety of beam intensity, energy and focusing conditions is reported.

	STAR is an advanced Thomson source of monochromatic and tunable, ps-long, polarised X-ray beams in the 40-140 keV range. The commissioning has started at the Univ. of Calabria (Italy). The light source is driven by a high-brightness, low-emittance electron beam produced in a LINAC allowing for the source tunability and spectral density. This note reports on an emittance measurement schema based on the insertion of a slit mask in the vacuum chamber dedicated to the photocathode laser entrance. Results of the simulation of the measurement technique are reported, and the use of the data for the optimisation of the accelerator performance are detailed. The experimental setup and the application developed in EPICS for image recording and analysis are also described.

	New generation of Compton sources are developing in different countries to take advantage of the photon energy amplification given by the Compton backscattering effect. In this framework the Eurogammas international collaboration is producing a very high brilliance gamma source for the Nuclear Pillar of the Exterme Light Infrastructure program (ELI). At present there is a lot of effort in the mass production of all the components and in the developments and tests of the different high technology devices that will operate in the gammas beam source, like the optical recirculator and the high gradient - high average current warm C band accelerating sections. In this paper we will provide a general overview of the GBS status and of the perspectives for the future integration phase.

TUPAB048	Long Beam Pulses With SLED Compression in DAΦNE LINAC	1434

	The DAΦNE LINAC is a ~60 m long, S-band (2856 MHz) linear accelerator, made up by four 45 MW klystrons with SLED compression, and by 15 travelling-wave, 2/3p, SLAC-type, 3 m long accelerating sections. It serves as injector of the DAΦNE e⁺ e⁻ collider, with 510 MeV, 10 ns long, electron and positron pulses, and the Beam-Test Facility extraction line, with variable beam energy and intensity and with pulses from 1.5 to 40 ns. A new pulsing system for the gun allows longer beam pulses, but the shape of the accelerating field in the sections due to the SLED compression has to be taken into account. We describe the tuning of the RF power, phase and delays in the pre-buncher, buncher and following accelerating sections, and the results of the tests performed in order to reach >200 ns 500 MeV electron pulses and the characterization of the quality of the beam in terms of energy spread, time distribution, etc.
