5 Subtasks realization proposition (1/2) ● Realization environment: High level applications will be developed mainly in the MATLAB environment. Control functions, data processing tools, optimization toolboxes and other features available in Matlab can be used for the application structure development, different solution work performance evaluation (simulation in Simulink). ● Tools: ● MATLAB with toolboxes, ● C/C++ compilers, ● DOOCS tools (servers, DDD for GUI realization, standalone applications)

6 Subtask realization proposition (2/2) ● Implementation evolution: Starting from the MATLAB realization level some of the HLA will migrate to the lower level (like adaptive feedforward, loop gain and phase meas/set, detuning and loaded Q, meas/set, field measurement (ucal/calibr), vector sum calibration meas/set, klystron realization and others). Some application's will be placed in the. The final decision concerning algorithm's placement will be taken during the implementation phase of work in agreement with the experts responsible for low level application's implementation.

7 Cooperation with different WP. ● Feedback controller (some HLA's have to be extended to the controller level (for instance klystron linearization)), ● Low Level applications (first development of LLA in the HL), ● Automation (HLA's managed by the FSM, common interface design), ● DataBase (coefficient storage, tables storage).

11 Introduction ● Goals / deliverables: – Developed and documented procedures for LLRF systems operations, commissioning and service. – Implemented procedures Matlab scripts (sequencer that will use the available DOOCS signals). ● Scope: – Procedures requested for commissioning of each LLRF system that will be installed in XFEL project. – Procedures for individual LLRF system operation as well as work coordination of multiple system. – Procedures for machine servicing during the operation

12 Subtask list

13 Subtasks realization proposition ● Realization: Procedures will be documented and placed in the database for future usage by operator and experts. The documentation will be created using worked out template that will be filled and verified with experts during FLASH operation and XFEL systems constructions. The description of the procedure will consist of: - prerequisits and pre-conditions, - procedure body, - machine postconditions. The set of MATLAB script will describe sequences of activities that have to be performed in order to move system from the beginning state to the expected state. Tools: ● MATLAB ● DOOCS tools (servers, DDD: GUI realization, FSM sequencers creator)

14 Cooperation ● Procedures development and than verification requires tight cooperation with the particular subsystem experts. Beside the LLRF experts also cooperation with: S. Schreiber, S. Simrock, K Honkavarra, S. Choroba, V. Katalev and others is planed. Moreover among the crew that will realized this work package, 70 % of people will have to be experienced FLASH operators. ● As far as procedures will be used by the automation as a expert knowledge the description of the procedures will be standardized.
