B9 DIAMOND XBPM DETECTOR
Nanometer Precision for X-ray Beams
The B9 Diamond XBPM Detector is used for the control of the beam position in experimental beam lines at Synchrotron Light Sources. This detector is an intercepting four-quadrant X-ray beam position detector. The B9 Diamond XBPM Detector provides high X-ray transparency and is therefore suited for soft X-rays beams. The detector is UHV compatible.

The μ-gap® of the Diamond XBPM Detector makes it most suitable for high-precision measurements of X-ray beams with a beam diameter in the sub-micron range: a nanometer position resolution is provided for sub-micron beams, and 10-3 of the beam size for standard beam sizes, respectively.
Ideal for precision measurements of X-ray beams in the sub-μm range.

  • nano-XBPM for sub-micron X-ray beams in the nm range.
  • micro-XBPM for X-ray beams in the μm range.
ADDITIONAL PRODUCT INFORMATION
The Diamond XBPM Detector is used for X-ray beam profile measurements. An example is shown in the Figure, where the profile of an elliptical 13 keV X-ray beam with 20 μm x 10 μm was measured with a step size of 6 μm.

The excellent homogeneity of the Diamond XBPM Sensor allows to perfectly reproduce the beam profile.
The excellent transparency of the Diamond XBPM detector prevents the disturbance of the X-ray beam. The transmission of the detector is >90% for X-ray energies above 7.8 keV. This makes it best suited as beam monitor at the experimental beam lines of Synchrotron Light Sources

The detector has a linear response to the beam intensity of X-ray beams over 10 orders of magnitude. The beam position as well as the beam intensity is measured with this beam-intercepting monitoring device.
