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)

Non-silicon sensors (FMF and KIT)
Crucial for hard X-rays. Needs: crystal growing and characterization; contacts and flip-chip technology at low temperatures (65K 55 μm pixels)
Silicon is not a great X-ray absorber…

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
- Cheaper than MRT
Ideal for regular mass screening
