TESLA Brochure - ACFA Joint Linear Collider Physics and Detector ...

The thirst for knowledge and the yearning to
explore new frontiers have led mankind to embark
upon journeys across the oceans,through
the deserts, and even to the moon. These same desires
have also compelled us to conduct empirical research
into the world around us. Scientists invented
the telescope and the microscope to see the vast and
the tiny more clearly.Theories were developed to explain
the images obtained and predict phenomena
as yet unseen. The picture of the world thus created
has been undergoing refinement ever since.
The 20th century has seen the development of
three of the cornerstones of modern physics: quantum
mechanics, relativity theory and the discovery
of antimatter. Together they have helped us understand
the nature of matter and are deservedly regarded
as one of mankind’s greatest achievements.
It was only through the development of increasingly
powerful particle accelerators that it became
possible to gain deep insight into the building blocks
of matter. Currently our most precise “microscopes,”
these accelerators allow us to probe into the secrets
of the big bang.They are also sources of intense electromagnetic
radiation, which are used to perform
pioneering investigations in the fields of physics,
chemistry,geology,biology and medicine.
The TESLA project at DESY was established within
the framework of an international collaboration to
help us better understand the universe and our immediate
surroundings. This brochure provides an introduction
to TESLA, which has been designed to explore
previously uncharted territory—both as a
particle accelerator and as an intense X-ray laser.
In addition to arousing your curiosity,our brochure
has been conceived to provide you with a better idea
of what TESLA is all about and what it is capable of.
We also hope it will answer some of your questions
and encourage you to come to DESY for an up-close
look at the cutting edge of scientific research.
Pleasant reading,
AlbrechtWagner
