Medipix
Medipix2 and Medipix3 are collaborations between number of European Universities and Research Institutes. The aim of the Collaboration is to carry out the design and evalutation of the semiconductor pixel detectors called Medipix (or newly Timepix). The hybrid silicon pixel detector device Medipix was designed for imaging by single quantum counting in each pixel. The device consists of a pixelated sensor chip and a read-out chip containing the amplifier, discriminators and counter(s) for each pixel. In our institute we are devoloping DAQ hardware (USB
interface) and software (Pixelman). Of course we are also users of these devices.
We use Medipix devices for several imaging techniques:
These imaging techniques are applied to:
Medipix is also used in experiments of fundamental physical research:
We use Medipix devices for several imaging techniques:
- X-ray microradiography and tomography, phase sensitive radiography,
- Neutron imaging
- XRF imaging,
- Imaging with heavy charged particles,
- Imaging in CINAA,
These imaging techniques are applied to:
- Medical and biological imaging,
- Material science (Dynamic defectoscopy - XRDD)
