class IpmFexConfigV1

Configuration for the feature extraction of LUSI In-situ Intensity-Position Monitor, composed of four silicon diodes arranged around the cross-section of hte x-ray beam to detect back-scattered Compton photons off a thin low-Z material window just downstream. The response from each diode is separately digitized and made available for calculation of the X-ray beam position and intensity at the location of the window.

class PimImageConfigV1

Configuration information for the LUSI Pop-in Profile Monitors: YAG crystals used in the vacuum path of the FEL converts x-rays into visible light. Video cameras with zoom lenses are used to image the beam profile screens.
