International Radiation Detectors (IRD) has announced the AXUV 100GX Absolute X-ray photodiode.
The X-ray detector possesses known active silicon thicknesses and 100 per cent internal quantum efficiency, allowing absolute measurement of X-ray flux with energy of 100keV and beyond.
X-ray responsivity measurements performed at PTB Germany confirm that the responsivity of AXUV 100GX devices can be calculated from their known silicon thickness.
The AXUV 100GX features a large (100mm2) active area with room-temperature operation and a small detector footprint.
It is simple to use and, unlike other X-ray detectors, requires no external voltage for operation.
The nitrided-oxide front window provides up to a Gigarad (SiO2) of radiation hardness which is 10,000 times greater than standard PIN silicon photodiodes.
Photodiodes with directly deposited, thin metallic filters are available for reducing response to visible light by several orders of magnitude.
IRD's advanced sensors are used internationally by synchrotron scientists and by space scientists for solar spectrum studies.
They are available for shipping now.
