    (+5 VDC) and communications (USB, RS232, or Ethernet). An auxiliary connector provides several additional inputs and outputs, used if the X-123 will be integrated with other equipment. This includes an MCA gate, timing outputs, and eight SCA outputs. The X-123SDD is supplied with data acquisition and control software.

    X-123 Options and Variations Detector The X-123 is available with any of Amptek’s standard detectors: FastSDD, SDD, SiPIN, and CdTe. Each of these is recommended for a different application and the X-123 hardware will only accommodate one detector type.
  • Page 4 XRF for rare earth metals, lead, mercury, and other higher Z materials. Extender In the X-123, the detector is mounted on an extender, as seen in the photo above. This is usually convenient for placing the detector inside shielding and in close proximity to a sample. The standard X-123 has a 1.5”...

    (at its option) a defective instrument upon return to the factory. This warranty does not apply in the event of misuse or abuse of the instrument or unauthorized alterations or repair. AMPTEK, INC. shall not be liable for any consequential damages, including without limitation, damages resulting from the loss of use due to failure of this instrument.

    Fe at full cooling. Refer to Amptek’s detector specifications for more information. Processing, physical, and power The DP5 specification table is identical to that found in the “User Manual for Amptek’s DP5 Product Family”. The physical and power specifications are listed below. Physical Dimensions 7 x 10 cm x 2.5 cm (2.7 x 3.9 x 1 in)
  • Page 7 At full cooling, T=70 C, the X-123 draws about 0.7 A at 5 V, or 3.5 W. If the detector is not cooled as much, power dissipation decreases to less than half of this. The table above is for a typical detector, but the actual value depends on the type of detector (e.g.

  • Page 10: Thermal

    Thermal The X-123 dissipates up to 3.5 W of power. It is important that the body of the X-123 be attached to a heat sink. If proper heat sinking is not used, then the X-123 chassis temperature rises, and thus the detector temperature rises and spectroscopic performance is compromised.
  • Page 11 Schematic of power supply architecture. Turn-On Transients The figure below illustrates the transient currents seen as the X-123 turns on. 1) When 5 VDC is first applied to the power input, a large transient current is drawn to charge up the 50 F of input capacitance, from the input capacitors on all the supplies.

  • Page 12: 123 Design

    X-123 Design Detector and preamplifier The X-123 uses the same detectors as Amptek’s other products. There are no changes to the detectors and all detector options are available. The preamplifiers have the same basic circuit as the PA210 and PA230 units. They run from +/-5 V.
