Overview

The X-123 represents the culmination of 14 years of X-ray detector development at Amptek.  Our philosophy has always been to create small, low power, high performance instruments while keeping them simple
to operate.  The X-123 exemplifies this philosophy by providing in a single package the XR-100 Detector and its
Charge Sensitive Preamplifier; the DP5 Digital Pulse Processor with pulse shaper,  MCA, and interface; and thePC5 Power Supply.  All that is needed is a 5 Volts DC input and a USB or RS232 connection to your computer.

INTERFACE SOFTWAREADMCA: The X-123 can be controlled by the Amptek ADMCA display and acquisition
software. This software completely controls and configures the X-123, and downloads
and displays the data. It and supports regions of interest (ROI), calibrations, peaksearching, and so on. The ADMCA software includes a seamless interface to the XRF-FP
quantitative X-ray analysis software package. Runs under Windows 98SE or later (32bit only) on PC compatible computers. Windows XP PRO SP2 or later recommended.
DPP API: The X-123 comes with an Application Programming Interface (API) in theform of a DLL library. The user can use this library to easily write custom code to control the X-123 for custom applications or to interface it to a larger system. Examples
are provided in VB, VC++, etc. on how to use the API. A Window CE/Pocket PC version
is also provided.
VB Demonstration: The VB demonstration software runs on a personal computerand permits the user to set the X-123 parameters, to start and stop data acquisition,and to save data files. It is provided with source code and can be modified by theuser. This software is intended as an example of how to manually control the X-123
through either the USB or RS-232 interface using the most basic calls without the DPP
API. This is primarily needed as an example when writing software for non-Windowsplatforms.

X-123 Description

Amptek’s specialty is X-ray spectrometers, which aresmall, low power, high performance, and simple to operate.  
The X123 combines in a single package Amptek’s standard,high performance X-ray spectroscopy components: the XR100CR detector and preamplifier, DP5 digital pulse processor
and MCA, and PC5 power supply.  The result is a complete
integrated system which can fit in your hand.  In many commercially available systems, the preamplifier alone has moresize, mass, and power than this integrated system.  It requires
only 2 connections to run: +5 VDC power and a standard RS232 or USB bus.  With the X-123, anyone can rapidly obtainhigh quality X-ray spectra.

ration options are available and they are selected by software
over a RS-232 interface, and (3) improved stability and reproducibility.  The DP5 digitizes the preamplifier output, applies
real-time digital processing to the signal, detects the peak
amplitude (digitally), and bins this value in its histogramming
memory, generating an energy spectrum.  The spectrum isthen transmitted over the DP5’s interface to the user’s computer.  The Amptek DP5 has 6 main function blocks to implement these functions: (1) an analog prefilter; (2) an ADC; (3)a digital pulse shaper; (4) pulse selection logic; (5) histogramlogic, and (6) interfacing hardware (which includes a microcontroller) and software.

The typical detector is a Si-PIN photodiode: X-rays interacting in the silicon create an average of one electron/holepair for every 3.62 eV of energy lost in the silicon, which is theinput signal.  

The power supply is Amptek’s PC5, a single board.  Theinput is approximately +5 VDC with a current of about 200mA.  The PC5 uses switching supplies to produce all the low
voltages required for the digital processor and the preamplifier.  It also includes a high voltage multiplier to produce thedetector bias voltage, up to 400 V, and supply for the thermoelectric cooler which provides closed loop control witha maximum temperature differential of 85˚C.  Both of thesesupplies are adjusted at the factory for a particular detector.

The detector is mounted on a thermoelectric cooler
along with the input FET and coupled to a custom charge
sensitive preamplifier.   The thermoelectric cooler reduces
the electronic noise in the detector and preamplifier, but thecooling is transparent to the user: it operates like a room temperature system.   The charge-sensitive preamplifier uses anovel feedback technique, injecting reset pulses through thehigh voltage connection to the detector.
The pulse processor is the DP5, a digital pulse processor
which replaces both the shaping amplifier and multichannel
analyzer (MCA) found in most analog systems.  The use of digital technology improves several key parameters:  (1) better
performance, specifically better resolution and operation at
higher count rates; (2) greater flexibility since more configu-

The complete system is packaged in 7 x 10 x 2.5 cm3aluminum box, with the detector mounted on an extender.  
In its standard configuration, only two connections are required: power (+5 VDC) and serial (either USB or RS232).  TheDP5 board supports several additional inputs and outputs, if
the X123 will be integrated with other equipment.  This includes an MCA gate, a memory buffer select signal, timing
outputs, and SCA ouputs.  Please contact Amptek Inc. or see
the DP5 specifications for further information.

X-123 Application: RoHS / WEEE Compliance

The X-123 does not sacrifice performance for size.  The resolution for
the 5.9 keV peak of 55Fe is 145 eV FWHM to 260 eV FWHM depending on
detector type and shaping time constant.  Since the X-123 is a complete
packaged spectrometer, it is the perfect choice for fast-track product development and will provide the OEM with the quickest time to market.

The RoHS / WEEE directive requires the electronics industry to certifythat products comply with maximum concentration amounts of particular elements and compounds (Cr VI, Pb, Cd, Hg, Br PBB/PBDE) by July 2006.  
The X-123 provides OEMs and end users with a powerful X-Ray Spectrometer system in one convenient, small, easy to use instrument that canbe quickly implemented to minimize time to market.  No additional engineering is required on the spectrometer end since all the connections
have been made internally.  All that is needed is a +5 Volts DC input power
and a USB or RS232 connection to a computer.
