Erasmus programmes in the cherne activities

The Erasmus Programme (EuRopean Community Action Scheme for Mobility of University Students) is a European Union student exchange programme established in 1987. The CHERNE Courses from PAN (2002) till SARA were organized with the support of Erasmus Programme, the last courses with the support of IP Erasmus programme. CHERNE Prague group evaluates this activity as very successful.

CHERNE 2013, Salamanka 4. - 7. June 2013

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). IEAPis also users of these devices.
