1 Summary of Kick-Off Meeting: AWAKE Technical Board 9 April 2014 E. Gschwendtner, 11 April 2014 1

2 Motivation Based on the experience in the last months (since the AWAKE experiment got approved), there is an urgent need to restructure and better organize the AWAKE collaboration in order be more efficient to meet the experimental goal of having first proton beam to the plasma cell in 2016 and electron acceleration in 2017. – Too many parallel issues/contacts – Lack of information distribution – Integration of the experiment at CERN covers every equipment from institutes. We need an institution where all issues concerning the design, installation and integration of the AWAKE experiment are coordinated and addressed: – Follow-up the technical progress of the different groups/tasks: Groups/institutes explain what they do and issues must be made aware to all concerned. The work is justified in front of the collaboration and put on the table. – Providing specifications of the technical implementation. – Milestone tracking and scheduling. – Take technical decisions. – Follow-up and documentation (minutes, reviews) We need an institution where the the required performance of the experiment and the physics goals are defined: E.

4 Technical Coordinator Mandate Coordinating the design, installation, integration and interfaces of the experiment. Providing a resource loaded planning and milestone tracking of the experiment. Providing specifications for the technical implementation of the experiment. Monitoring, on behalf of the Collaboration, on a regular basis the technical progress of the different tasks through technical reviews, test results and site visits. Organizing and steering the hardware and beam commissioning of the experiment. Organizing and preparing the operation of the experiment. E. Gschwendtner, 11 April 2014 4

5 Technical Board The Technical Board (TB) is the principal steering group in all matters of technical coordination and is chaired by the technical coordinator. The TB is composed of the Task-Group Coordinators (TGCs), CERN Work-package leaders (WPL) and sub-work-package leaders (SWPL). Members of the MB and the Deputy Technical Coordinator are ex-officio members of the TB. In the spirit of the mandate of the Technical Coordinator (TC) the TGCs, WPLs and SWPLs work together with and report to the TC on all issues covered by the mandate of the TC. The TC may set up, in consultation with the TB and on an ad-hoc basis, special working groups or task forces to address specific technical issues or advise on certain technical solutions. The TB is authorized to take technical decisions, which the TB deems not to have a significant impact on performance or cost of the AWAKE experiment. More important technical decisions are prepared in the form of a proposal by the TB for discussion at and decision by the MB. The Technical Coordinator or, in his absence, the Deputy Technical Coordinator chairs the TB. The TB meets regularly, typically once a month. The TC may call for extraordinary meetings of the TB to deal with specific or urgent topics. The decisions of the TB are recorded in minutes, which are made available to the Collaboration. E.

21 Summary Important meeting to coordinate and address AWAKE experiment design, integration, installation issues. We have a short time-scale of preparing the experiment and tight planning Allows the tasks owners and work-package leaders to get ‘proactive’ and raise important points. – Integrate not only the experiment, but also the task owners into the organization. – Task owners and work-package leaders are supposed to take their role very seriously. Working very closely with the Physics and Experiments Board (PEB). – Many points are defined by physics needs, e.g. electron spectrometer design, … Regular meetings: ~every month Then: Follow-up! Decisions and Action Items are summarized in minutes. E. Gschwendtner, 11 April 2014 21 Typical Agenda of the TB: – Progress reports from task owners/WP leader – Planning – Follow-up – Matters Arising

22 Next Steps E. Gschwendtner, 11 April 2014 22 Task group owners makes sure that the dead-lines in the current tables (and those which come up) are taken care of. Until the next TB meeting each task-owner – Prepares for each task the milestones Allows to check how this fits into the general planning and whether there are any issues for any tasks. – completes the tables shown in the kick-off meeting (tasks to be done/needed input from others) – Fills out the equipment needs table.  Next TB meeting: Monday 19 May 2014 at 14:00
