Karlsruhe Institute of Technology: What is it? How does it relate to detectors Marc Weber (KIT) Marc Weber, KIT, Feb. 21, 2012 1
Where is KIT ? Central and scenic location in Southern Germany State of Baden-Württemberg Close to Black Forest Close to France 1h by train from Frankfurt airport 2h by car from Switzerland 3h by train from Paris Marc Weber, KIT, Feb. 21, 2012 2
What is KIT ? Karlsruhe University + FZK = KIT Marc Weber, KIT, Feb. 21, 2012 3

Faculties Most relevant for detector portfolio are arguably: Physics Electrical engineering and information technology Informatics (“computer science”) Mechanical engineering Marc Weber, KIT, Feb. 21, 2012 7
Institutes Of the 157 institutes are arguably most relevant for detectors: • IEKP, IKP, IPE, ISS/LAS (particle physics, astroparticle physics, electronics, synchrotron radiation) • IHE, IMS, IQP, ITIV (high frequency radiation and electronics, superconducting detectors, quantum photonics, embedded systems) • IMT, INT (micro and nano technology) Marc Weber, KIT, Feb. 21, 2012 8

Non-silicon sensors (FMF and KIT) Silicon is not a great X- ray absorber… CdTe detector Crucial for hard X-rays. Needs: crystal growing and characterization; contacts and flip-chip technology at low temperatures (65K 55 μ m pixels) Pictures: M. Fiederle (FMF und KIT) Marc Weber, KIT, Feb. 21, 2012 12
3D Ultrasonic Computer Tomography (USCT) • Application: mammography • 10% of western women develop breast cancer • High survival probability if detected early • 3D USCT gives excellent spatial resolution in 3D • No X-rays 3D USCT • Cheaper than MRT Volume 8 liter < 200 μ m Resolution Ideal for regular mass screening Channels 1413 Power < 1.5 kW Data Rate 50 Gb/s Trigger N/A 30 ° C Temperature Mass - Radiation hardness - Marc Weber, KIT, Feb. 21, 2012 13
