The sileye-altcriss experiment on board the international space station

The Altcriss project was submitted in response to ESA AO-2004. It was approved in March 2005 and begun in December 2005 with Progress 21-P launch from Baikonur. It is currently operating on board the International Space Station, performing a survey of the radiation environment and the effectiveness of shielding materials from cosmic rays. It uses the active silicon detector Sileye-3 and a series of passive dosimeters (CR-39, TLD). The detectors have currently been operational in different location of the Pirs (docking) and Service module of the Russian section of the Station. The project is expected to continue up to 2008
