Bruker Launches the METALJET™, a Novel and Extremely Bright Microfocus X-Ray Source for Structural Biology Applications
Nov. 18, 2012 06:00 PM
At the 2012 triennial International Small-Angle Scattering Conference (http://sas2012.com),
Bruker launches the METALJET, a novel and extremely bright
microfocus X-ray source for structural biology applications. The unique METALJET
is now offered exclusively by Bruker as a source option for D8
VENTURETM protein crystallography
systems and for NANOSTARTM Small
Angle X-ray Scattering (SAXS) systems.

The METALJET source for Bruker structural biology systems
was developed in collaboration with Excillum AB and Incoatec GmbH as the
most intense home-lab microfocus X-ray source available today outside of
synchrotron beamlines. This revolutionary new liquid metal source
technology is well suited to meet the ever-increasing demands of modern
structural biology, and particularly of protein crystallography and of
small angle X-ray scattering.
Just like conventional rotating anode generators and microfocus sources,
the METALJET uses the impact of electrons onto a metal
target to generate X-rays. However, the solid anode of conventional
generators is replaced by a high-speed jet of liquid metal that can
accept a much higher power load. The result is an X-ray beam that is
brighter than what is currently achievable with the most powerful
laboratory X-ray sources.
The transmission and delivery of such a small X-ray beam also requires
technical innovations in the design of X-ray optics, since a smaller
X-ray source requires greater precision during the deposition process of
the multilayers for X-ray mirrors. The new HELIOS MXTM
X-ray optics, developed by Incoatec for the METALJET,
transmits the X-rays to the crystal sample in a uniformly small
diameter, greatly exceeding the intensity of traditional X-ray sources.
Despite this unparalleled analytical performance, the new METALJET
source also features a cost of ownership that is very competitive with
conventional rotating anode sources.
The unprecedented brightness of the new METALJET source
will allow researchers to bring into the home lab many experiments that
previously could only be accomplished at a synchrotron. The METALJET
enables structural biologists to collect data on smaller, more
weakly-diffracting crystals, improving home-lab productivity more than
ever before.
Oscar Hemberg, PhD, the CEO of Excillum AB, said: “We are very proud
that Excillum’s liquid-metal-jet-anode X-ray source technology now will
be introduced to Bruker’s customers after two years of intense product
development and thorough internal evaluations at Bruker.”
Dr. Vernon Smith, Business Development Manager for Structural Biology at
Bruker AXS, stated: “Adding the METALJET to our D8
VENTURE and NANOSTAR systems tremendously
strengthens our position in the high-end structural biology market. Our
customers need cutting-edge tools for their demanding research projects.
Introducing the best-performing X-ray source for the home lab underlines
our commitment to meet our customers’ demands and to be at the forefront
of technology.”
Professor Tim Salditt of the University of Goettingen, Germany, added:
“I was the first customer of a METALJET X-ray source back
in 2009, and I must say that in addition to the obvious benefits of the
extreme brightness of the source I am very impressed with the stability,
reliability and ease of use of the technology.”
