  • Complete X-Ray Spectrometer X-55

    The X-55 is the smallest complete X-ray spectrometer on the market. The size of Amptek’s XR100 (the industry standard detector and preamplier),it contains the detector, preamplier, and also a high performance digital pulse processor and all power supplies. It has all the capability of the X-123 in a package the size of the XR100. The mounting holes and envelope are identical to that of the XR100, so that the X-55 Complete Spectrometer can be dropped in the space that previously had only the detector and preamp. This reduces system size and also reduces cabling complexity and simplies grounding and shielding.

    Overview
       The X-55 is the smallest complete X-ray spectrometer on the market. The size of Amptek’s XR100 (the industry standard detector and preamplier), it contains the detector, preamplier, and also a high performance digital pulse processor and all power supplies. It has all the capability of the X-123 in a package the size of the XR100. The mounting holes and envelope are identical to that of the XR100, so that the X-55 Complete Spectrometer can be dropped in the space that previously had only the detector and preamp. This reduces system size and also reduces cabling complexity and simplies grounding and shielding.

       The X-55 can be provided with any of Amptek’s FastSDD? (25 mm2 or 70 mm2), standard SDD, or SiPIN (6 mm2, 13 mm2, or 25 mm2) detectors. It includes Amptek’s new DP5-X digital pulse processor, with all the capabilities of the DP5: a resolution as low at 124 eV FWHM at 5.89 keV, an output count rate over 1 Mcps, etc. The power supplies are all switching regulators for high eciency. The X-55 supports USB and RS232 communications, using the same protocol (FW6) as Amptek’s other DP5 products, and is compatible with software already developed for the DP5.




    SPECIFICATIONS

    The key signal processing, MCA, and communications specications are largely the same as the other products in Amptek’s DP5 family. Please refer to the “User Manual for the DP5 Product Family” for more complete documentation and discussion.

    Controls
    Gate input: Pulses accepted only when gated on by
    external logic. Input can be active high or active low.
    Software controlled.
    Operating Modes
    MCA mode
    Most common operating mode. The DPP acquires a pulse height spectrum, using the MCA in the FPGA, and reads this to the computer, over one of the interfaces, one software request. Readout intervals usually range from 0.1 s to a few seconds.
    Counting mode
    By reading only the status packet over one of the interfaces, one can obtain the input and output count rates at much shorter intervals than the entire spectrum can be read. Requires custom software.
    Other modes
    Supports List Mode and SCA Mode.
    Communications
    USB 2.0 full speed (12 Mbps)
    RS-232 at 115.2k or 57.6k baud
