Detector Material
Constellation can fabricate detectors of many different sizes. We
generally categorize our detectors into one of three categories, x-ray
detectors for spectroscopy, gamma ray detectors for spectroscopy, and
x/gamma ray detectors for counting (no resolution quoted).
Resolution for spectroscopy x-ray detectors is normally quoted in eV FWHM
at 5.9 keV (the Fe-55 electron capture x-ray line). Resolution for
spectroscopy gamma ray detectors is normally quoted in %FWHM at 662 keV
(the principle gamma line of Cs-137), but depending on your application,
we will also quote at other resolutions such as 122 keV, 60 keV, 117 keV,
and 133 keV. Custom detector sizes are available. Mercuric
iodide probes can be fabricated as small as 1 mm3 or
smaller for surgical probes, wound probes, etc. We can also build
large arrays and stacked arrays of detectors up to 25 mm x 25 mm in area.
Our standard detector sizes are:
