Mission & Research Questions The development of state-of-the-art detector technologies for upgrades of the LHC experiments as well as for experiments at the future e+e- linear collider and the development of multi-purpose alignment systems. Collaborations with industrial partners are actively pursued. How: development of Relations with ‘experiments’ robust gaseous charged particle detectors read-out by pixelised CMOS ASICs as active anode large area position sensitive sensors for X-ray imaging wide range of alignment systems based on RASNIK Thin gas (1 mm) detectors for possible (vertex) upgrade Atlas at SLHC Partner in EUDET and LCTPC collaborations for readout of large TPC Partner in RELAXD project together with PANalytical (NL), Canberra (B) and IMEC (B) Collaboration with CERN on alignment system for CLIC (Rasclic) 7 Sept 2007 Nikhef evaluation: Detector R&D

Plans and ambitions in relation to mission Gossipo2 Acquire more expertise in deep-submicron chip design, post-processing, high-density interconnect, 3D-integration and sensor development In collaboration with partners in particle and X-ray physics, technical universities (e.g. MESA+), and industrial partners (e.g. PANalytical) Keep leading role in pixelized readout of gas detectors Hire new “young blood” Medipix ASIC Multi-layered chip carrier board Quad sensor 7 Sept 2007 Nikhef evaluation: Detector R&D
