  1. Goal: use photon BPM for FOFBi.e. separate e-beam and opt-elems. instabilities "standard XBPM" monochromatic pinkbeam whitebeam

  2. Current installations at PXI (pinkbeam)9/8/2019 first light on SiC XBPM Shutter Pinkbeam 800W (36W) <1% at 12.4keV 80µm C window 1th BLADE Whitebeams 2kW (5.2mm gap)

  3. Current installations at PXI (pinkbeam) • 2 µm XBPM was installed 1 month ago at PXI pinkbeam (after diamond window). • The measured current is several order of magnitude lower than the expected one.

  4. Current installations at PXI (pinkbeam)PRELIMINARY RESULTS FFT of SiC XBPM FFT of Blades BLADES SiC XBPM

  5. "Long term goal": 1Development of multifunctional photon XPM semiconductor based internal photoemission array of 4 devices -- full membrane, -- "high res." --"small pin-hole": 2.0x1.0mm2 --"blade opening": 3.4x2.2mm2 --"large pin-hole": 6.0x4.0mm2

  6. "Long term goal": 2Development of combined position/profile monitor for pinkbeams GOTTHARD FEMTO AMP copper PINKBEAM 2x2 XBM for beam position@ MHz/nm pixelated XBM for beam profile at kHz

  7. "Long term goal": 2Development of combined position/profile monitor for pinkbeams

  8. Conclusions & outlook • First successful installation of SiC XBPM in pinkbeam location (800W beam power, PXI) • XBPM can be baked, compatible with UHV (1E-10) • Extension towards simulatenous profile&position presented within the AIRES2 call of proposals • Systematic comparison of SiC XBPM with 1th/2th blades. Establishment/test of FOFB based on SiC XBPM
