DLR at a glance
DLR is Germany´s national research center for aeronautics and
space. Its extensive research and development work in Aeronau-
tics, Space, Transportation and Energy is integrated into national
and international cooperative ventures. As Germany´s space agen-
cy, DLR has been given responsibility for the forward planning and
the implementation of the German space program by the German
federal government as well as for the international representation
of German interests. Furthermore, Germany's largest project-
management agency is also part of DLR.
Approximately 6,200 people are employed at thirteen locations
in Germany: Koeln (headquarters), Berlin, Bonn, Braunschweig,
Bremen, Goettingen, Hamburg, Lampoldshausen, Neustrelitz,
Oberpfaffenhofen, Stuttgart, Trauen and Weilheim. DLR also
operates offices in Brussels, Paris, and Washington D.C.
DLR's mission comprises the exploration of the Earth and the
Solar System, research for protecting the environment, for envi-
ronmentally-compatible technologies, and for promoting mobility,
communication, and security. DLR's research portfolio ranges
from basic research to innovative applications and products of
tomorrow. In that way DLR contributes the scientific and technical
know-how that it has gained to enhancing Germany's industrial
and technological reputation. DLR operates large-scale research
facilities for DLR's own projects and as a service provider for its
clients and partners. It also promotes the next generation of
scientists, provides competent advisory services to government,
and is a driving force in the local regions of its field centers.

Quality control in concentrating solar
power (CSP) plants is of outmost impor-
tance for their performance. Optical pro-
perties durability and geometric precision
of the components and the assembly
have very strong influence on the overall
energy efficiency and profitability. The
specific components such as mirrors,
receivers, support structures and tracking
as well as their overall matching and per-
formance in the solar field merit special
dedication.
At the current stage of development of
the concentrating technologies, test
methods and procedures ensuring the
required performance of CSP compo-
nents and systems have recently been
established or are in preparation.
The Solar Research Division of the DLR
Institute of Technical Thermodynamics
has provided significant contributions by
developing quality criteria, test benches
and test procedures based on decades of
experience in this field of technology at
the test sites in Köln, Stuttgart and
Almería.

Solar Research
The Center belongs to the Solar Research Department
of DLR's Institute of Technical Thermodynamics. With some 70
employees it is one of the world's largest research groups in the
field of concentrating solar thermal systems. DLR is engaged in
this area since the late 1970s. Besides the experimental possibi-
lities offered by the Plataforma Solar de Almería, DLR operates a
25 kW solar furnace, a 60 kW high flux solar simulator and furt-
her solar test facilities and laboratories in Cologne and Stutt-
gart. DLR's Solar Research develops and tests new components
for concentrating solar systems in cooperation with industrial
partners or by their assignment. Technical and economic feasibi-
lity studies are carried out, collectors as well as other optical and
thermal systems are built and analyzed, and large international
projects are managed. A strong cooperation with Aachen Uni-
versity is established through a joint Professorship for Solar Tech-
nology that allows direct supervision of student research,
degree and doctoral dissertations.

DLR at a glance
DLR is Germany´s national research center for aeronautics and
space. Its extensive research and development work in Aeronau-
tics, Space, Transportation and Energy is integrated into national
and international cooperative ventures. As Germany´s space agen-
cy, DLR has been given responsibility for the forward planning and
the implementation of the German space program by the German
federal government as well as for the international representation
of German interests. Furthermore, Germany's largest project-
management agency is also part of DLR.
Approximately 6,200 people are employed at thirteen locations
in Germany: Koeln (headquarters), Berlin, Bonn, Braunschweig,
Bremen, Goettingen, Hamburg, Lampoldshausen, Neustrelitz,
Oberpfaffenhofen, Stuttgart, Trauen and Weilheim. DLR also
operates offices in Brussels, Paris, and Washington D.C.
DLR's mission comprises the exploration of the Earth and the
Solar System, research for protecting the environment, for envi-
ronmentally-compatible technologies, and for promoting mobility,
communication, and security. DLR's research portfolio ranges
from basic research to innovative applications and products of
tomorrow. In that way DLR contributes the scientific and technical
know-how that it has gained to enhancing Germany's industrial
and technological reputation. DLR operates large-scale research
facilities for DLR's own projects and as a service provider for its
clients and partners. It also promotes the next generation of
scientists, provides competent advisory services to government,
and is a driving force in the local regions of its field centers.
