  Soleil is currently testing new beam loss monitors to replace its pin-diode based existing system. The new detectors are made of plastic scintillators associated with photomultiplier and connected to Libera BLM dedicated electronics. This new detector should provide both fast (turn by turn) and slow (averaged) loss measurements, post mortem capabilities and should be less sensitive to the beam directivity compared to the pin-diodes. Different methods for a relative calibration of the modules are under investigation, either using a diode (LED) or a cesium radioactive source. Calibration results and first measurements with beam are presented.

  Soleil is currently testing new dose monitors based on RadFET transistors. This new detector at SOLEIL will provide a measurement of the dose received by equipment that are damaged by the radiations in the storage ring, and to anticipate their replacement. This monitor should be very compact to be placed in tiny areas, sensitive to all kind of radiation and low cost to install many of them around the ring. A readout electronic module is being developed in-house, and a first prototype has been build and installed on the machine. Description of the system and first results recorded on the machine are presented.

WEPB01 Photon Beam Imager at SOLEIL 425

    SOLEIL, Gif-sur-Yvette, France
 
  In one of the long straight sections of SOLEIL is installed a pair of canted in-vacuum undulators for the ANATOMIX and NANOSCOPIUM beamlines. Since the upstream undulator radiation can potentially damage the downstream undulator magnets, an accurate survey of the respective alignment of the two devices is mandatory. An XBPM has been initially installed for this purpose in the beamline frontend. For redundancy and further analysis, an X-ray imager was then designed and added just downstream the XBPM. It is made of a diamond plate that can be inserted into the upstream beamline frontend at low current. Fluorescence of the Nitrogen impurities in the diamond is imaged on a CCD to check that the upstream radiation is not hitting the downstream insertion device. We present the commissioning of this new device together with its first results in operation.
