Very low pressure is maintained in the tube (around 10-9 mbar). A synchrotron is a machine about the size of a football field, which accelerates electrons to almost the speed of light. Now when the electrons gain maximum energy, the radio-frequency oscillator is turned off and a larger current is sent through auxiliary coils so that the electrons change their orbit radius due to unstable magnetic flux. } 0000019738 00000 n The advantages of a synchrotron beamline compared to the laboratory equipment are therefore (i) higher resolution of the measurements due to a possible smaller beam size down to a few micrometer or even submicrometer and (ii) the possibility of simultaneous measurements of SAXS and WAXD and possibly other methods such as XRF to measure the calcium content in the bone sample. 610 Parker Square Flower Mound, Texas 75028 Indications of use and product features may also vary by country or region.
