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)
Technical Board
We need an institution where the the required performance of the experiment
and the physics goals are defined:

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.

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.

Meeting Structure
•
Today I summarize for each task a first (uncompleted) draft of the milestones and the
matters arising.
– This serves also as guideline for open issues and defines first milestones.
•
From next meetings on
Each task-owner must report to the Technical Board about the milestones, latest
results, open points and possible issues.
•
Check how the progress fits into the planning and what are the dead-lines and key
results to answer issues.
•
All decisions, milestones, dead-lines will be summarized in minutes!
Agenda:
– Planning
– Progress reports from task owners/WP leader
– Follow-up
– Matters Arising

Summary
•
The Technical Board is an extremely useful forum to discuss all aspects of the
experiment which need to be covered for the design, integration and installation.
•
Working very closely with the Physics and Experiments Board (PEB).
•
Short time-scale of preparing the experiment and the tight planning
– Need good coordination
•
Task owners and work-package leaders are supposed to take their role very seriously
– Provide the necessary results, inputs and put issues on the table as soon as possible.
•
The next Technical Board is on Monday, 19 May 2014 at 15:30.
– The task owners and WP leaders present the completed tables (tasks to be done/input
needed from others)
– Answer specific questions on equipment needs and send to Ans
– Progress reports from task group owners/WP leaders
– Planning
 Dates for decisions will be synchronized with overall planning
