  Beam-loss level monitoring is a powerful diagnostic tool concerning accelerator health. Particles leave the vacuum pipe for various reasons, such as intrabeam scattering (Touschek effect), residual gas molecules, closed orbit distortions or mechanical obstacles (aperture restrictions, installation errors). These can be identified by appropriate measurements. The steady-state beam loss level varies throughout the machine and has to be measured and documented for further reference. Besides general radiation safety purposes, changes (especially increases) occurring after machine upgrades are of special interest. When simple monitoring of average beam loss fluctuations is insufficient, problem diagnostics should be further enhanced by correlating beam loss monitor (BLM) detector readout with events in the machine. For best flexibility, pulses should only be counted at certain conditions and during well defined time slots synchronized with the current machine operation cycle. In cooperation with Cosylab, such an advanced BLM acquisition system was developed for the Electron Stretcher Accelerator ELSA (University of Bonn, Germany), allowing various optimized acquisition modes.

  MicroIOC LR-BPM product offers complete beam position monitoring solution to be used on transfer lines or linear accelerators where bunch repetition rate is low (< 50Hz). It consists of Log ratio Beam position monitor (LR-BPM) modules from Bergoz instrumentation and of microIOC analog to digital acquisition unit (microIOC-ADA) from Cosylab. In this paper we present the detailed operation of the system and the results from testing that was performed at Soleil accelerator in May 2008. In this particular test microIOC LR-BPM proved to be a complete stand alone solution with only signals from the beam pickup detectors as inputs. It is capable of providing up to 8 X-Y beam positions and since its design is based on a single board computer inside the ADA unit it is easily integrated in a higher level control system software. Furthermore the position data is available to the control system clients over the external network via Ethernet link. EPICS was used as a control system although the product can accommodate other types of control systems that can run on x86 platform.

  Every beamline is different, which makes it impossible to buy a control system of the shelf. Nevertheless well tested and customizable building blocks can be prepared, which are then put together according to customer requirements. Delivering a fully operational control system is not just software development, but also gathering specifications, writing documentation, testing the hardware and trimming the software on site. Based on the delivery of a number of working beamlines, this paper will prove that we have optimized all stages and can guarantee that the purchased control system will be delivered on time, will work according to specifications and will be properly documented. The customers can also count on support.
