5. Characterization of fading effects of a MOSFET semiconductor dosimeter to be used on an X-ray laser
University essay from Stockholms universitet/Medicinsk strålningsfysik (tills m KI)Abstract : In the European XFEL, electrons bunches are accelerated up to 20 GeV and thenenter undulators where coherent X-rays are produced which can be used for imaging atva molecular level. Electrons may stray from the path and hit the permanent magnets inthe undulators. READ MORE
