	XAIRA, the hard X-ray microfocus beamline at ALBA, includes three monochromatic fluorescence screens and one water cooled white beam monitor in its layout, mounting respectively YAG:Ce and polycrystalline CVD diamond as scintillator screens. All monitors share the same design scheme, with a re-entrant viewport for the visualization system that allows reducing the working distance, as required for high magnification imaging. The scintillator screen assembly is held by the same CF63 flange, making the whole system very compact and stable. The re-entrant flange is driven by a stepper motor actuated linear stage that positions or retracts the screen with respect to the beam path. To cope with high power density (18, 6 W/m2) on the white beam monitor 100 µm-thick diamond screen, an InGa-based cooling system has been developed. The general design of the new fluorescence screens, to be used also in other ALBA’s upcoming beamlines, with particular detail on the water-cooled white beam monitor, is described here.

XAIRA, the hard X-ray microfocus beamline at ALBA, includes three monochromatic fluorescence screens and one water cooled white beam monitor in its layout, mounting respectively YAG:Ce and polycrystalline CVD diamond as scintillator screens. All monitors share the same design scheme, with a re-entrant viewport for the visualization system that allows reducing the working distance, as required for high magnification imaging. The scintillator screen assembly is held by the same CF63 flange, making the whole system very compact and stable. The re-entrant flange is driven by a stepper motor actuated linear stage that positions or retracts the screen with respect to the beam path. To cope with high power density (18, 6 W/m2) on the white beam monitor 100 µm-thick diamond screen, an InGa-based cooling system has been developed. The general design of the new fluorescence screens, to be used also in other ALBA’s upcoming beamlines, with particular detail on the water-cooled white beam monitor, is described here.
