Cavity performance
Accelerating gradient of all accelerator modules
assembled average gradient above TESLA
500 needs of 23.4 MV/m gradient spread
of individual cavities decreased
TESLA Test Facility at DESY
TTF operation for gt 13,000 h Technical
readiness has been demonstrated
Greg Loew (ICFA Seminar 2002) If one had to
launch a project for 500 GeV TESLA would be the
only one having essentially proven performance
specs for the main linac RF-system
TTF Operation forExperiments and Beam Studies
Cavity Treatment
Electropolishing of Cavities
Collaboration CERN/KEK/ Saclay/DESY
The path to 35 MV/m and 800 GeV
Electropolishing of cavities
Nine-cell cavities
Now four 9-cell cavities above 35 MV/m
35 (TESLA 800)
Transition from single-cell results to multi-cell
results again successful
Side Planning Status
Research Campus Ellerhoop
Agreement between the states Schleswig-Holstein
and Hamburg for joint legal procedure Environment
al impact study complete
We prepare to start the legal procedure required
for an implementation at the site in a few
months, as part of the overall feasibility study
The German Science Council (Wissenschaftsrat)
The Wissenschaftsrat (WR) advises the Federal
Government and the state (Länder) governments.
Its tasks are - Recommendations on the
development of higher education
institutions, science and the research sector
- Considerations concerning quantitative and
financial effects The WR was asked in 2000 by
the federal and state governments to review
TESLA and 7 other proposals for large
infrastructure facilities
Statement by the WR (July 2002)
Theses by the WR on the significance of
large-scale facilities for basic scientific
-Basic scientific research plays a key role in
shaping the future worldwide -The opening-up or
development of totally new areas of research is
closely related to the availability of specific
new facilities -Large-scale facilities must
represent the distilled core of national and
international research collaboration and
scientific networks -One essential task to be
fulfilled in the operation of large-scale
facilities is that of linking high-ranking
scientific research closely with the training
of junior scientists and including them in
international research collaboration -With
large-scale facilities there must be long term
scientific visions, and the prerequisites for
technical innovations must be given -The
facilities should be set up as research
establishments organised under an umbrella of
multinational European or international
sponsorship and should be open to a broad
international usership -Large-scale facilities
must be centrally incorporated into the
strategic planning and research programme of the
institution(s) in charge and must be a core
element of the spectrum of tasks
WR-Statements concerning the X-FEL
The high luminosity and time resolution of the
X-FEL promises a new quality of experiments for
many areas of research in the natural, life,
material and geo-sciences. Due to the high
coherence of the photon radiation it will be
possible for the first time to extensively
analyse the structural and dynamic properties
of matter. use of the TTF has led to key
theoretical and experimental developments as
well as sweeping technological innovations, a
trend that is expected to continue in the future.
The Science Council requests the Federal
Government to give its binding consent to German
participation in the TESLA X-FEL project as soon
as possible after the revised project proposal
has been submitted
TDR Collider and FEL use jointly the first
section of the SC linac
Following the recommendation by the WR, the
planning is based on separate linac for X-FEL,
using same technology
New proposal submitted for meeting of the WR
this week
WR-Statement concerning the LC
The Science Council believes that an enormous
amount of knowledge about fundamental questions
concerning the micro- and macrocosmos will be
gained from the scientific questions that will be
examined using the TESLA linear collider. The
general feasibility of superconducting
accelerator technology was convincingly
demonstrated by the test accelerator (TTF)
installed at DESY.
The Science Council requests the Federal
Government to give its binding consent to German
participation in the project as soon as possible
after the project proposal has been submitted
with specific details concerning international
funding and international cooperation.
Memo concerning international cooperation
submitted to WR meeting
Next Steps
The statement is the final vote on each
initiative The WR regards the funding of
facilities of this size as continuous process Thu
s it considers the statement to be the basis for
further necessary discussions on support The WR
will submit concrete recommendations on the
priorities for implementation, which are based on
the present statement and which take into account
the subsequent science policy debate on the goals
and funding of the facilities
Scientific recommendations in a few
months Political decisions expected in 2003
International Linear ColliderDetector RD
Committee appointed to - describe the detector
RD required - list the RD efforts presently
ongoing - point out areas where efforts are
missing or inadequately covered Paper about the
world-wide effort written, serving as a starting
point. Web-page created
http// containin
g links to all subdetector areas The purpose of
this web-page is to help organise the RD efforts
more globally and to facilitate and foster
interregional co-operations. It continues from
the paper, serving as a continuous update.
