2. 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)

3. 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”

11. Currently, noise: 200 nm RMS per image drift: 9 μm·mHz RMS per image
Sensitivity test with a 500 kg load
(average 8 s – average 800 s):
signal of 500 nm observed
noise level around 20 nm RMS Hz
Possibility of use as seismometer; analysis Peru earthquake in progress
Currently, noise: 200 nm RMS per image
drift: 9 μm·mHz RMS per image
Both to be improved by factor 10 – (ongoing)
