Multi-port Readout Systems

With integral controller electronics designed to read out large format scientific and industrial multi-port CCD arrays from one, or four ports, these novel system deliver high sensitivity and 16-bit dynamic range. The thermoelectrically-cooled CCD and its multiport readout provide high frame rates without sacrificing low noise performance. The electronics unscramble the digital stream of data before transferring it to computer memory via the FireWire interface for easy post-processing or display.

Cesium Iodide (with Thallium) crystalline phosphor
For the application where highest possible resolution is a must Princeton Instruments has developed phosphors based on CsI:Tl crystalline structure for 8 keV, 25 keV and 60 keV X-ray energies. The crystalline needle structure of CsI:Tl has a few advantages over the powder phosphors (though it has lower absorption at x-ray energies < 33 keV). The needle structure of CsI:Tl acts as a light guide to transmit visible light generated from the absorbed X-ray photons and provides higher resolution than powder phosphor and preserves resolution when x-ray energy changes a little from experiment to experiment, and  provides more uniform light output. A special coating over the needle structure developed to preserve the high resolution also protects it from the moisture in the atmosphere. 

Gadolinium Oxy-Sulfide (with Terbium) powder phosphor – Gd2O2S:Tb
Princeton Instruments has developed two phosphors for 8 keV and 17 keV X-ray energies based on Gd2O2S:Tb powder. To provide highest possible resolution, small grain material is used on a mirrored Mylar. When large image area, high efficiency and lower costs are the considerations these phosphors are recommended. The Gd2O2S:Tb is recommended for x-ray energies < 33 keV as it has higher absorption efficiency and the CsI:Tl is recommended for x-ray energies > 33keV.
