2 GdA_CLIC meeting  The aim of this activity is to support the conceptual and technical design and preparatory actions for new research infrastructures, which are of a clear European dimension and interest.  Major upgrades of existing infrastructures may also be considered if the end result is intended to be equivalent to, or capable of replacing, an existing infrastructure. Design Studies_ Specific challenge

3 GdA_CLIC meeting Motivation:  Increasing interest by the Scientific Community for very compact Normal Conducting Linacs for FELs (~6 GeV, ~150m, for 1 Å wavelength). “Support for feasibility studies of new research infrastructures (i.e. Ankara University, Australian Synchrotron,….), or major upgrade of existing ones (i.e. SwissFEL,….)”. Advantages:  Compactness, possibility to go high repetition rate, costs. Aims and motivations

4 GdA_CLIC meeting Design Studies_ Specific challenge Objective Validate the X-band technology for FEL based photon sources, with the design and assembly of an X-band accelerating module to be tested with the beam. Focusing on: operating gradients, breakdown fault rate, alignment issues, wake fields effects, RF stability. The module will be based on: One RF power unit; RF pulse compressor and WG power distribution system; Two accelerating structures; Diagnostics; Mechanical supports and structure alignments.

6 GdA_CLIC meeting  If possible the X-band module would be installed at CERN CLIC Test Facility (detailed plans to be done when the project will be well defined).  Besides the gradient and the fault rate tests, this choice would also allow extensive beam tests with the CALIFES beam*.  Use of the existing diagnostics with an adequate upgrading (i.e. an X-band deflecting cavity….).  The objective is the evaluation of the beam brightness degradation due to wake fields, misalignments, etc. Installations and tests * May be at a reduced charge to improve the emittance

14 GdA_CLIC meeting Scoring Scores must be in the range 0-5. Half marks may be given. Evaluators will be asked to score proposals as they were submitted, rather than on their potential if certain changes were to be made. When an evaluator identifies significant shortcomings, he or she must reflect this by awarding a lower score for the criterion concerned. Thresholds The threshold for individual criteria is 3. The overall threshold, applying to the sum of the three individual scores, is 10. Evaluation process 1.Excellence 2.Impact 3.Quality and efficiency of implementation
