	Funding: Work partially supported by the Spanish Ministry of Science and Innovation under project AIC10-A-000441 and AIC-A-2011-0654. Among all the LIPAc/IFMIF accelerator diagnostics instrumentation, the Beam Position Monitors are a cornerstone for its operation. A new approach for the LIPAc/IFMIF beam position monitors acquisition electronics is proposed for the twenty BPM stations distributed along the accelerator. The new system under development is a fully digital instrumentation which incorporates automatic calibration of the monitors' signals and allows monitoring of both fundamental and second signal harmonics. The current state of the development and first experimental results of the system on the test bench will be presented.

MOPC44	A Gigabit Ethernet Link for an FPGA Based Beam Loss Measurement System	CERN, beam-losses, monitoring, LHC	178
	M. Kwiatkowski, M. Alsdorf, B. Dehning, W. Viganò, C. Zamantzas CERN, Geneva, Switzerland
	A new Beam Loss Measurement (BLM) system is under development at the European Organisation for Nuclear Research (CERN) within the LHC Injector Upgrade (LIU) project. The multi-channel system will measure the beam losses from various types of detectors with a high precision and wide dynamic range. Several modes of data acquisition are supported. The data rate in the single-channel mode is 16 Mbps and in the multi-channel mode 128 Mbps. The Gigabit Ethernet link is implemented in an FPGA, which allows both a high throughput and a quick validation of the digital data processing algorithms using standard PCs in the initial stages of the development. Both TCP and UDP protocols were explored. The implementation of the Ethernet link is flexible and proved to be highly reliable, leading to its planned use in other measurement systems developed at CERN. The implementation details of the Ethernet link and the results achieved will be described in this paper.

	Electron bunch length measurements are of crucial importance for many types of accelerators, including storage rings, energy recovery linacs, free electron lasers. Many devices and instrumentation have been developed to measure and control the electron bunch length. A very powerful class of diagnostic tools is based on the coherent radiation power emitted by the electron bunch, that allows a non-destructive shot by shot measurement, well suitable for bunch length control feedback implementation. However they usually provide measurements of the bunch length relative variation, and external instrumentation like a transverse RF deflecting cavity is usually needed to calibrate them and to obtain absolute bunch length estimations. In this paper we present a novel experimental methodology to self-calibrate a device based on diffraction radiation from a ceramic gap. We indeed demonstrate the possibility to use coherent radiation based diagnostic to provide absolute measurements of the electron bunch length. We present the theoretical basis of the proposed approach and validate it through a detailed campaign of measurements that have been carried on in the FERMI@Elettra FEL linac.

TUPF25	Beam Current Measurement System in CSNS LINAC	linac, beam-transport, vacuum, SNR	565
	P. Li, F. Li, M. Meng, T.G. Xu IHEP, Beijing, People's Republic of China
	The China Spallation Neutron Source is being constructed at Dongguan, Guangdogn province. Before RCS Ring there are three beam transport sections in CSNS LINAC : LEBT, MEBT, LRBT, where various beam measurement monitors will be installed. Beam Current Transformers (BCTs) have been designed to measure beam macro-pulse current that will operate between 5mA to 80mA . The BCTs have the same inductance but different size in these three sections. Besides, beam parameters should be monitored also between the DTL four parts. There is no BCT but a FCT would be installed after DTL1 due to space limit. So this FCT is planned to measure the macro-pulse current, and we have to proceed the acquired data to show the original macro-pulse waveform due to the FCT’s low inductance.

	C. Courtois, C. Doutresssoulles, B. Ducoudret, C. Jamet, W. Le Coz, G. Ledu, C. Potier de courcy GANIL, Caen, France
	The safety re-examination of existing GANIL facilities requires the implementation of a safety system which makes a control of beam intensities sent in the experimental rooms possible. The aim is to demonstrate that beam intensities are below the authorized limits. The required characteristics should enable the measurement, by a non-interceptive method, of beam intensities from 5 nA to 5μA with a maximum uncertainty of 5%, independently of the frequency and the beam energy. After a comparative study, two types of high frequency diagnostics were selected, the capacitive peak-up and the Fast current transformer. This paper presents the signal simulations from diagnostics with different beam energies, the uncertainty calculations and the results of the first tests with beam.

	The Brookhaven National Laboratory 200 MeV H⁻ LINAC beam instrumentation equipment has been in operation for four decades with various changes implemented over this period. There is a need to upgrade the entire beam instrumentation system of the LINAC to improve the diagnostics of the beam from the Low Energy Beam Transport Line through the LINAC and into the LINAC Booster Transfer Line and BLIP line. Profile Monitors, Current Monitors, Beam Position Monitors, Loss Radiation Monitors, and Emittance Measurement devices are to be designed and implemented over the next three years. This upgrade will improve the operation reliability, beam quality and beam losses. Additional improvements will be obtained by designing the beam instrumentation system to integrate with other proposed diagnostics and malfunction detection and display upgrades in the LINAC Control Room to improve the overall performance of the LINAC.

	Parts of the linac of the European Spallation Source will consist of cryogenic cavity modules. In between these will be warm sections at room temperature to host amongst others the beam instrumentation. Each of the warm sections will host two beam position monitors and one or two other instruments, which might be a beam current monitor, invasive and non-invasive transverse beam profile monitor, bunch shape monitor, or halo monitor. The concept of the warm section layout will be shown and the planned instrumentation will be presented.
