MAIN ACTIVITIES DURING THE PAST YEAR:
• Visit to Frascati to start contacts with INFN about the kicker design. (February 05)

SHORT TERM ACTIVITIES:
• Conceptual Design of the Kicker Magnet ( March 05)
• Drawings for Fabrication ( April 05)
CONCLUSION: An overall delay of about 4 months, but correction actions
can be taken to have the magnet finished by the end of 2006

MAIN ACTIVITIES DURING THE PAST YEAR:
• First meeting with SLAC to discuss a possible collaboration with LLNL
for the development of the kicker pulser. (Very Unlikely). (May 05)
• Contact with Spanish Industry to develop this pulser which has other
potential applications (Feb-Nov 2005)
SHORT TERM ACTIVITIES:
• To be defined
CONCLUSION: A decision must be taken on how to continue with this
development. Spanish participation on her own seems very difficult

MAIN ACTIVITIES DURING THE PAST YEAR:
• Market survey for PETS fabrication in Spain (Jan-Sep 05)
• Purchasing of the HFSS software (August 05)
• A new engineer joints the team, devoted specifically for this development (Nov 05)

• Stay at CERN of the CIEMAT engineer for the full PETS design (Nov-?? 06)
CONCLUSION: Relevant modifications have been made in
the planning due to the delay in the starting of the new
engineer (design has been substituted by fabrication)

Conclusions


The Superconductivity Laboratory CIEMATCEDEX has been collaborating with different
linear accelerators since 2000: TESLA500, XFEL,
ILC, CLIC.
Former contributions were superconducting
magnets, now we are also including HF
electromagnetic devices.
