TI - Evaluation of Libera Single Pass H for ESS LINAC
J2 - Proc. of IBIC2014
AB - The Beam Position Monitor system of the ESS linac will include in total more than 140 BPM detectors of different sizes and types. The resolution and accuracy of the position measurement with the nominal 62.5 mA beam current and 2.86 ms pulse width need to be 20 ?m and 100 ?m respectively, and those of the phase measurement are 0.2 deg and 1 deg respectively. The BPM system also needs to work successfully under off-optimal conditions, ex. with a de-bunched beam, or with the current and pulse width being as low as 6 mA and 10 ?s respectively. Options for the implementation of the ESS BPM electronics include: 1) a custom or commercial front-end card combined with a commercial digitizer with in-house developed firmware and 2) a fully commercial off the shelf system. Libera Single Pass H is an instrument intended for phase, position and charge monitoring in hadron and heavy ion LINACs. The instrument was tested at the ESS laboratory, to probe the feasibility of operation with ESS beam conditions. To give a realistic picture of the device performance, different testing setups were evaluated, including all the signal and environment conditions foreseen for the final ESS linac operation. The results present resolution, precision and accuracy evaluations, as well as stressful long-term and stability tests. This paper presents the achieved results of the Libera Single Pass H for the ESS beam parameters.
