Medipix USB

Medipix2 is a single-photon counting pixel readout chip, developed by the CERN Medipix collaboration:

http://medipix.web.cern.ch/MEDIPIX/Medipix2/indexMPIX2.html

Currently, we are using the Medipix USB interface developed by IEAP at Czech Technical University, Prague, to read out these detectors.

Medipix detector

Using the interface

Information on using the interface can be found on IEAP's website.

USB interface main page: http://aladdin.utef.cvut.cz/ofat/others/USB_Interface/index.html . As well as information on the interface, this has the USB driver needed to operate the device.

Pixelman control software: http://aladdin.utef.cvut.cz/ofat/others/Pixelman/Pixelman.html . Includes a guide to using the software, and a download of the software. To use recent versios of the software, new Windows libraries must be installed (available from the download page).

Additional notes

Power supply: In principle, the USB interface should be able to run from the 500mA that the USB port supplies. However, when running like this errors sometimes occur, because the interface attempts to draw too much current and the voltage drops. (According to the FAQ, this can depend on the USB controller within the PC.) The most convenient solution is to put a powered USB hub between the PC and the interface. This also is a useful way of extending the length of cable between the PC and lab setup.

If you have any other comments, please add them!
