6. Motivation of Restructuring
Transition from LHC construction to Operation
Start of New R&D activities
New non-LHC Experiments may appear in the future
Staff numbers decrease
Overlapping activities and competences in DT1 and DT2

7. Mandate of DT Group
The mandate of the PH/DT group comprises development, construction, operation and maintenance of particle detectors for the experiments at CERN. The group clusters common services and infrastructure which are at the benefice of all experiments at CERN, i.e. gas system support, thin film lab, silicon facility with bond lab, irradiation facilities, magnet support, B-field mapping, instrumentation and controls.
The group’s activities are concentrated in four areas:
Completion and consolidation of the ongoing LHC projects;
Maintenance and operation: piquet services, shutdown and preventive maintenance, repairs and infrastructure support;
New detector projects:, participation in new developments (LHC upgrade);
R&D: participation in common R&D activities in strategic fields;
Years 8/9/10
~70-80%
~10-20%
~5-10%

8. How to structure the group ?
Linear Structure:
‘Autonomous’ sections for each activity
Matrix Structure:
Vertical Sections according to professional categories
horizontal project structure
Many sections with little interaction.
Easy to manage, but inflexible.
Few sections with much interaction. Challenging to manage, but very flexible.
DT Model:
All services and infrastructure activities in one section (mix of phys/eng/tech)
All experiment related activities are distributed over 4 sections, arranged according to professional
Categories.

9. Proposed Group Structure

Physicists
Engineers
Technicians
~ 27
Physicists
~ 13
1-2 Eng/Phys

~ 18
1-2 Eng/Phys

~ 80 people (incl. some transferred from experiments)

10. “Modus Operandi” 5 sections (just for illustration) ~20 projects
Every project is performed by a ‘well defined’ team of people.
Every project is led by an internal project leader.
For every experiment we have an ‘Experiment Contact Person’.

11.  We need to involve Department and LHC experiments in its management.
DT group will represent ~20% of PH total staff.
It will be the main resource in PH for detectors and their infrastructure.
 We need to involve Department and LHC experiments in its management.
Meets ~2x per year.
Review of activities and resource attribution. Long term planning.
Meets ~1-2x per month.
Follow-up of projects, short-term resource and priority changes.
ECP = Experiments Contact Person
