3. WP6: start to end modelling integrated performance studies of the facility
Performing start to end simulations, which cover the beam transport from the cathode to the FEL exit for Soft X-Ray & Hard X-Ray including;
including Space Charge effects, Coherent Synchrotron Radiation in magnetic compressors, Wake Field effects in the X-band linac and in undulators.
Providing key parameters and performance estimates of the overall facility.
Definition the basis for technology choices for critical components and for developing detailed designs of subsystems and components including:
accelerating structures, undulators, power sources, modulators, pulse compressors, waveguide network, instrumentation and alignment system.
Mechanical tolerance studies will be also performed. it will include
beam-based alignment and tuning methods that can relax tolerances.
Development of tools for modeling the machine, as the basis for the final integrated performance studies.

4. WP flow chart WP6 is closely linked to WP3, WP4 and WP5.
WP6 may start by receiving input from WP2.
At start stage it is not necessary to combine the results of WP3, WP4 and WP5

5. Task 6.1: Study of the existing design and simulation tools for the evaluation of the facility performance. Analyse and improve their capabilities if necessary.
We already started collecting the available simulation tools for the section of interest i.e.
Gun&injector: 7! Parmela, Astra, GPT, Andrea’s code. . . ?
Linac: 7! Placet, Elegant, GPT, LiTrack, MadX ?
FEL: 7! Genesis, Ginger. . . ?
Other tools not related with beam dynamics in particularly RF structure optimization tools
Cost optimization tool for entire facility
Task 6.2: Using the above mentioned tools, design and evaluate the performance of the machine from the e-gun up to the undulator exit.
By definition the facility parameters the tools will be selected and the integration will be performed with some optimization algorithm

7. Deliverables brief description and month of delivery
D6.1: A report providing a global analysis of the most advanced computer codes available for the facility design and performance evaluations (R, PU, M18).
D6.2: Final report of the accelerator lattice and FEL design and performance (R, PU, M36).
there will be internal reports as well which are going to be prepared frequently.

15. Conclusion
WP6 will mainly be doing beam dynamics and FEL generation simulations
As a first step we are collecting the available simulation tools at collaborating institutions
We will also collect the previous studies which are related to our WP
The parameter table will quickly be checked and preliminary simulations will be prepared for sub-sections of entire facility
As soon as we get feedback from WP2 the simulations will be adapted to the requirements.
