Bruker AXS Exhibits New QUANTAX(TM) QUAD EDS System at Pittcon 2006Chip Layout of Novel Ultrafast and Sensitive SDD Detector-ba

At Pittcon 2006, Bruker AXS Microanalysis will exhibit
its recently announced QUANTAX(TM) QUAD ultra-fast and sensitive EDS
system for X-ray microanalysis on electron microscopes. QUANTAX(TM)
QUAD features the unique XFlash(R) QUAD detector -- the first
four-channel 40 mm(2) Silicon Drift Detector (SDD) for
Energy-Dispersive Spectroscopy (EDS) systems mounted on electron
microscopes. Powered by ESPRIT(TM) software, the QUANTAX QUAD delivers
significantly faster EDS results across a broad range of applications.
It is especially suitable for field emission scanning electron
microscopes, environmental and low vacuum scanning electron
microscopes. The new high-end XFlash QUAD detector complements the
existing Bruker AXS QUANTAX EDS product line.
   Four independently operating 10 mm(2) Silicon Drift Detectors
(SDDs) with integrated anodes and FETs form the heart of the XFlash
QUAD detector. This arrangement provides the high energy resolution of
a single 10 mm(2) crystal at four times the count rate, accepting
maximum input count rates in excess of 2,000,000 cps. Cooled by
Peltier elements, the XFlash QUAD detector requires no liquid nitrogen
and is vibration and maintenance-free. Standard energy resolution is
better than 133eV (MnKa) at 10,000 cps, and energy resolution of
better than 127 (MnKa, 10,000 cps) is available upon request.
   Thomas Schuelein, Vice President for Microanalysis at Bruker AXS,
stated: "This cutting-edge new product fits right into our broader EDS
strategy, as it complements our already existing range of
industry-leading Silicon Drift Detectors. While our proven 10 and 30
mm(2) single-channel XFlash SDDs are expected to remain the standard
for the vast majority of EDS applications, the unique new XFlash QUAD
SDD is ideal for optimizing count rate at low beam current conditions
and helps make new analysis techniques, like spectral imaging, even
more efficient and powerful. All of our QUANTAX EDS customers can
upgrade to the XFlash QUAD in the future, should their applications
require this performance."
