TESLA 500
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 > 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

The path to 35 MV/m and 800 GeV
Electropolishing of cavities:
Nine-cell cavities
Now four 9-cell cavities
above 35 MV/m

Function
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 research
-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
11
The X-FEL
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
12
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
13
Next Steps
The statement is the final vote on each initiative
The WR regards the funding of facilities of this size as continuous
process
Thus 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 R&D
Committee appointed to
- describe the detector R&D required
- list the R&D 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://blueox.uoregon.edu/~lc/randd.html
containing links to all subdetector areas
The purpose of this web-page is to help organise the R&D efforts more
globally and to facilitate and foster interregional co-operations. It
continues from the paper, serving as a continuous update.

International Linear Collider Detector R&D
1) Project Days
Facilitate and intensify international cooperation on
subdetector R&D
Add one day to each of the next regional meetings
dedicated to specific subdetector R&D
with Video/Phone conferencing to the other regions
Jan 08 2003 UTA
Mar 31 2003 NIKHEF
summer 2003 Asia
Vertex and Intermediate Tracker
European contact: C.Damerell
Main and Forward Tracking

International Linear Collider Detector R&D
2) Global Detector Network (GDN)
Idea of the Global Accelerator Network follows the example
of the large detector collaborations
Idea of the Global Detector Network follows the example of
the GAN: mirror control rooms off site
and run experiment remotely
Need to discuss all aspects (technical feasibility, security, social…)
related to remote running.
Two Contact Persons per region (to be) nominated
Europe: Joachim Mnich and Vaclav Vrba
Start discussion Sunday during Detector Plenary session
