Mission & Research Questions

• How: development of

• Relations with ‘experiments’

Mission: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 alignmentsystems. Collaborations with industrial partners are actively pursued.

Plans and ambitions in relation to mission

• 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”

Accelerator length: 2 x 21 kmNumber of elements: 21,000Number of ‘4 m’ RASNIKs: 42,000Number of ‘100 m’ RASNIKs: 600

Sensitivity test with a 500 kg load

(average 8 s – average 800 s):

● signal of 500 nm observed● noise level around 20 nm RMS

Images @ 12.5 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 – 100 (ongoing)
