	Funding: Work supported by Brookhaven Science Associates, LL C under Contract No. DE-AC02-98CH10886 with the U.S. Dept. of Energy The operating parameters for Brookhaven National Laboratory's Low Energy RHIC Electron Cooling (LEReC) project create a unique challenge. To ensure proper beam trajectories for cooling, the relative position between the electron and the ion beam needs to be known to within 50μm. In addition, time of flight needs to be provided for electron beam energy measurement. Various issues have become apparent as testing has progressed, such as mismatches in cable impedance and drifts due to temperature sensitivity. This paper will explore the difficulties related to achieving the level of accuracy required for this system, as well as the potential solutions for these problems.

MOPG15	BPM Electronics for the ELBE Linear Accelerator - a Comparison	electronics, controls, embedded, pick-up	75
	U. Lehnert, A. Büchner, B. Lange, R. Schurig, R. Steinbrück HZDR, Dresden, Germany
	The ELBE linear accelerator supports a great variety of possible beam options ranging from single bunches to 1.6 mA CW beams at 13 MHz bunch repetition rate. Accordingly high are the dynamic range requirements for the BPM system. Recently, we are testing the Libera Spark EL electronics to supplement our home-built BPM electronics for low repetition rate operation. Here, we discuss the advantages and disadvantages of the two completely different detection schemes. For integration of the Libera Spark EL into our accelerator control system we are implementing an OPC-UA server embedded into the device. The server is based on the free Open62541 protocol stack which is available as open source under the LGPL.

MOPG49	A Precise Pulsed Current Source for Absolute Calibration of Current Measurement Systems With No DC Response	operation, power-supply, impedance, hardware	165
	M. Krupa, M. Gąsior CERN, Geneva, Switzerland M. Krupa TUL-DMCS, Łódź, Poland
	Absolute calibration of systems with no DC response requires pulsed calibration circuits. This paper presents a precise pulsed current source designed primarily for remote calibration of a beam intensity measurement system. However, due to its simple and flexible design, it might also prove interesting for other applications. The circuit was designed to drive a load of 10 Ω with current pulses lasting a few hundred microseconds with an amplitude of 1 A and precision in the order of 0.01%. The circuit is equipped with a half-bridge for precise determination of the absolute output current using the 0 V method. This paper presents the circuit topology and discusses in detail the choice of the critical components along with their influence on the final achieved accuracy. The performance of the built prototype of the current source is presented with laboratory measurements.

TUPG09	Novel Electrostatic Beam Position Monitors With Enhanced Sensitivity	simulation, quadrupole, linac, monitoring	333
	M. Ben Abdillah IPN, Orsay, France
	Beam Position Monitors (BPM) measure the beam transverse position, the beam phase with respect to the radiofrequency voltage, and give an indication on beam transverse shape. Electrostatic BPMs are composed of four electrodes that transduce the associated electromagnetic field to the beam into electrical signal allowing the calculation of the beam parameters mentioned above. During commissioning and/or experiences phases that needs very low beam current; the precision of the BPM measurements is reduced due to the low sensitivity of electrostatic BPM to beam current. This paper addresses the design, the realization and the testing of a new set of electrostatic BPMs with large electrodes. It emphasizes the strong points of these BPMs in comparison with BPMs present in SPIRAL2 facility

	An experiment to test the Time Reversal Invariance at COSY (TRIC) is under the preparation at the Forschungszentrum Jülich. This experiment requires a precise measurement of the beam life time. A high resolution beam current measurement system, based on Fast Current Transformer (FCT), is under the development for the COSY storage ring. The signal from the FCT is measured by a modern lock-in amplifier which is read out by a dedicated DAQ over an Ethernet. Additional instruments, equipped with Ethernet interface, can be implemented into this DAQ and read out synchronously with other systems necessary for the TRIC experiment. Relative resolution of 10^-4, sufficient for the TRIC experiment, has been demonstrated at the test bench in the laboratory. Preliminary results of the system commissioning at COSY will be presented.

TUPG45	The CERN Beam Instrumentation Group Offline Analysis Framework	framework, database, extraction, software	449
	B. Kolad, J-J. Gras, S. Jackson, S.B. Pedersen CERN, Geneva, Switzerland
	Beam instrumentation systems at CERN require periodic verifications of both their state and condition. Presently, experts have no generic solution to observe and analyse an instrument's condition and as a result, many ad-hoc Python scripts have been developed to extract historical data from CERN's logging service. Clearly, ad-hoc developments are not desirable for medium/long term maintenance reasons and therefore a generic solution has been developed. In this paper we present the Offline Analysis Framework (OAF), used for automatic report generation based on data from the central logging service. OAF is a Java / Python based tool which allows generic analysis of any instrument's data extracted from the database. In addition to the generic analysis, advanced analysis can also be performed by providing custom Python code. This paper will explain the steps of the analysis, its scope and present the kind of reports that are generated and how instrumentation experts can benefit from it. We will also show how this approach simplifies debugging, allows code re-use and optimises database and CPU resource usage.

WEAL02	The Wall Current Transformer - a New Sensor for Precise Bunch-by-Bunch Intensity Measurements in the LHC	vacuum, impedance, network, operation	568
	M. Krupa, M. Gąsior CERN, Geneva, Switzerland
	The Wall Current Transformer (WCT) is a new bunch-by-bunch intensity monitor developed by the CERN Beam Instrumentation Group to overcome the performance issues of commercial Fast Beam Current Transformers (FBCT) observed during Run 1 of the LHC. In the WCT the large magnetic cores commonly used in FBCTs are replaced with small RF transformers distributed around the beam pipe. Rather than directly measuring the beam current, the WCT measures the image current induced by the beam on the walls of the vacuum chamber. The image current is forced to flow through a number of screws which form the single-turn primary windings of the RF transformers. The signals of the secondary windings are combined and the resulting pulse is filtered, amplified and sent to the acquisition system. This paper presents the principle of operation of the WCT and its performance based on laboratory and beam measurements.

	Silicon Photomultipliers (SiPM) enable fast low-level light detection and even photon counting with a semiconductor device. Thanks to a now matured technology, SiPMs can be used in a variety of applications like: Medical imaging, fluorescence detection, range-finding and high-energy physics. We present different possible application of SiPMs for beam instrumentation. First, we discuss timing properties of SiPMs, and how to optimize them for high rate environments enabling photon counting. This requires to understand the dependence of SiPM pulse shape on its configuration (total area, cell size, capacitances, etc) and analyse dedicated front end electronics techniques. Finally, based on the experience of several projects aiming to develop trackers for high energy physics, we present some ideas to develop beam monitoring instrumentation based scintillating fibers coupled to SiPMs, where radiation hardness of scintillating fibers can be an important concern.
