	Funding: Supported by the H2020 project AIDA-2020, GA no. 654168 In the last 11 years, the Beam-Test Facility (BTF) of the Frascati DAΦNE accelerator, gained an important role in the development of particle detectors. e^- or e⁺ beams can be extracted to a dedicated transfer line, where a target plus a dipole and collimator, can attenuate and select secondary particles in a narrow p (<1%) band. BTF can provide tuneable beams in a wide range of: energy (to 750 MeV/540 MeV for e⁻/e⁺), charge (up to 10¹⁰ e/bunch) and pulse length (1.4-40 ns) up to 49 Hz rep. rate. Beam spot and divergence can be adjusted, down to sub-mm sizes and 2 mrad. Photons can be produced on a target, and energy-tagged inside the dipole by Si micro-strip detectors. A shielded W target is used for neutron production: about 8 10-7/pr, 1 MeV n are produced. 200 beam days are delivered to about 20 groups/year. A dedicated experiment PADME for the search of light dark matter, like dark photons, ALPs, etc., was approved aiming at a sensitivity up to m=26 MeV/c2. An upgrade program of the facility is proposed, along 3 lines: consolidation of the LINAC, in order to guarantee a stable operation in the longer term; upgrade of the energy up to 1 GeV; doubling of the BTF beam-lines.

TUPG59	Bunch Extension Monitor for LINAC of SPIRAL2 Project	linac, ion, detector, diagnostics	486
	R.V. Revenko, J.L. Vignet GANIL, Caen, France
	A semi-interceptive monitor for bunch shape measure-ment has been developed for the LINAC of SPIRAL2. A Bunch Extension Monitor (BEM) is based on the registra-tion of X-rays emitted by the interaction of the beam ions with a thin tungsten wire. The time difference between detected X-rays and accelerating RF gives information about distribution of beam particles along the time axis. These monitors will be installed inside diagnostic boxes on the first five warm sections of the LINAC. The monitor consists of two parts: X-ray detector and mechanical system for positioning the tungsten wire into the beam. Emitted X-rays are registered by microchannel plates with fast readout. Signal processing is performed with constant fraction discriminators and TAC coupled with MCA. Results of bunch shape measurements obtained during commissioning of RFQ for SPIRAL2 are presented.

	The electron beam quality determines the main synchrotron radiation characteristics therefore beam diagnostics is of great importance for synchrotron radiation source performance. The real-time processing of the electron beam parameters is a necessary procedure to optimize the key characteristics of the source using feedback loops. The frequency of electron beam cycling in the synchrotron storage ring is about 1 MHz. In multi-bunch mode electrons are grouped into a series of bunches. The bunch repetition frequency depends on the total number of bunches and usually reaches hundreds of MHz. The actual problem is to study the separate bunch dimensions behavior under multi-bunch beam instabilities. To solve this problem a turn-to-turn electron beam profile monitor is developed for Siberia-2 synchrotron light source. The linear avalanche photodiodes array is applied to imaging. The apparatus is able to record a transversal profile of selected bunches and analyze the dynamics of beam during 10⁶ turns. The recent experimental results obtained with the diagnostics are described.
