Sr-90 test data

The detector settings can be found in accompanying .dsc files. The distance from source to detector was 9.3 cm, the distance from source to aluminium was 4.0 cm.

Inside the zip file, the data for each thickness of aluminium is saved in a file with the thickness as its folder name. Data is stored in dataXXX.txt files in X,Y,C format, where X is the x-co-ordinate of the hit pixel in the Timepix detector's 256x256 pixel silicon sensor element, Y is the y-co-ordinate of the pixel, and C is the number of counts recorded in the pixel. The counts recorded is equivalent to the charge deposited in the pixel about a predetermined threshold value.
