Responsibility of technical sector for beamlines?
Strategic Plan: 2.2 Project organizationThe task of the Technical Sector is to design, build and operate the machine from the microtron to the front ends. The shielding wall between the storage ring and the experimental hall is the border line that separates what falls within the responsibility of the Technical Sector and what lies with the Scientific Sector. Nevertheless, though the installation of beamlines would normally be within the purview of the Scientific Sector it has been decided that provisionally the technical team will be in charge of this due to the lack of staff in the Scientific Sector. Beamlines will be built individually in coordination with the corresponding beamline scientists.
In any cases:We need one beamline-scientist for each BL to built it up!
