Responsibility of technical sector for beamlines? Strategic Plan: 2.2 Project organization The 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!
Status Accelerators: Microtron is running Booster built up started (expect operation end 2013) Storagering: Magnet / Vacuum Design ready (delivery till 2016) Building: Shielding wall is done Cooling plant nearly finished Purchasing Radiation Safety system started Beamlines: Floor-planes in work? Test of components started
Next Steps (2013) Accelerator: Finish built up of Booster and start operation End 2013 Start Purchasing of magnet system (design ready) To be delivered 2016 Start Purchasing of vacuum system (design ready) To be delivered 2016 Start Purchasing Piping Cooling Storagering To be finished 2015 Start Purchasing RF (cooperation with SOLEIL) To be delivered 2016 Floorplan! …
