X-Ray Detectors
The X-Ray radiation detectors are custom photodiodes, including the traditional Si-PIN diodes, Silicon Drift Detectors (SDDs), and CdTe Schottky diodes.
The detector is mounted on a two-stage thermoelectric cooler along with the preamplifier’s input transistor. The cooler keeps the detector and transistor at -25oC or below, reducing electronic noise without cryogenic liquid nitrogen and drawing <1W. This cooling permits high performance in a compact, convenient package, and has been critical to the development of portable XRF analysers and of high performance, bench top XRF and EDS systems.

FastSDD X-Ray Detectors for XRF/EDS
FAST SDD®
|
Unlike conventional SDDs which use a junction gate field-effect transistor (JFET) inside the hermetically sealed TO-8 package, along with an external preamplifier, the FAST SDD uses a complementary metal-oxide-semiconductor (CMOS) preamplifier inside the TO-8 package, and replaces the JFET with a metal-oxide-semiconductor field-effect transistor (MOSFET). This significantly reduces capacitance, providing much lower series noise and yielding improved resolution at very short peaking times.
The FAST SDD® uses the same detector but with a preamplifier giving lower noise at short peaking times. Improved (lower) resolution enables isolation/separation of fluorescent X-rays with close energy values where peaks would otherwise overlap, permitting users better identification all of the elements in their sample(s). Short peaking times also yield significant improvements in count rates; more counts provide better statistics. |
C-Series
|
C-Series” X-ray windows utilise silicon nitride (Si3N4) with an aluminium coating to extend the low energy response of our silicon drift detectors (SDDs) down to boron (B); they are available exclusively with the FastSDD®.
The Patented C-Series windows offer less attenuation (higher intrinsic efficiency) than the standard Be windows for X-ray energies below 1.5 keV (for elements below Al). The C windows are about a factor of 2 more efficient for Na Ka X-rays (at 1.04 keV) than the thinnest Be window (8 µm). With Be windows it is virtually impossible to measure elements below Na in the periodic table, and even Na and Mg are marginal. The Patented C-Series windows make it practical to measure light elements. |
EDS (SEM) FAST SDD® + C2 Window
|
This improved line of silicon drift detectors (SDDs) for energy dispersive spectroscopy (EDS) use within scanning electron microscopes (SEMs).
Using our proprietary Patented “C-Series” silicon nitride (Si3N4) X-ray windows, the low-energy response of our FAST SDD® extends down to beryllium (Be). The FAST SDD® with its high intrinsic efficiency is ideal for EDS, which is also known as energy dispersive X-ray spectroscopy (EDX or XEDS) and energy dispersive X-ray analysis (EDXA) or energy dispersive X-ray microanalysis (EDXMA). |
Si-PIN X-Ray Detectors
XR-100CR
|
The Si-PIN is a high performance thermoelectrically cooled X-ray detector. It is typically used in laboratory X-ray spectroscopy applications requiring moderate energy resolution and moderate count rates where cost is important. It is well suited to many XRF applications such as identifying metal alloys, verifying RoHS/WEEE compliance, and detecting lead in paint.

Beryllium Free X-Ray Windows
|
The introduction of Boron Carbide (B4C) windows for use with FAST SDD® and SiPIN detectors. The product offering is the result of a multi-year effort to provide end-users and OEM manufacturers with a high-performance window alternative to standard beryllium (Be) foils.

The X-123 is a complete X-Ray Detector System in one small box that fits in your hand.
The X-123 is a single package with the XR-100CR X-Ray Detector and its Charge Sensitive Preamplifier; the DP5 Digital Pulse Processor with pulse shaper, MCA, and interface; and the PC5 Power Supply. All that is needed is a +5 V DC input and a USB or RS-232 connection to your computer. |
CdTe X-Ray and Gamma Ray Detectors
XR-100-CdTe
|
The XR-100CdTe is a high performance x-ray and gamma ray detector, preamplifier, and cooler system using 5 x 5 x 1 mm Cadmium Telluride (CdTe) diode detector mounted on a two-stage thermoelectric cooler. The XR-100-CdTe is capable of detecting energies from a few keV to several hundreds of keV, with an efficiency that peaks from 10 to 100 keV.

PA-210 & PA-230
|
The AXR/PA-210 or AXR/PA-230, is the OEM preamplifiers that is compatible with can be used (Si-PIN, SDD, or CdTe) detector.
The customer needs to provide custom heat-sinking and a custom enclosure for the AXR/PA-210 or AXR/PA-230. If the PA210/PA230 Housings are used, additional heat-sinking to the Housings will be needed. Additionally, the customer needs to provide several external power supplies, a shaping amplifier and MCA, or digital processor, and communication with the host computer. |
Accessories
eMLC-1
|
eMLC-1 External Collimator is an accessory which can be used to reduce the flux of X-rays entering SDD and Fast SDD® X-ray detectors from wide angles, improving background and reducing spectral interferences.
The optimum external collimator depends strongly on the geometry of a particular instrument; many customers will design their own collimator for their application. This is a general purpose tool which helps in many applications and is a basis for customisation. |
