Strontium Decay Data

Data taken with Timepix hybrid silicon detector to measure the attenuation of beta particles from Strontium-90 in Aluminium of varying thickness.

Detector settings can be found in .dsc files alongside data. Distance from source to detector = 9.3cm,

Distance from source to Aluminium = 4cm.

Inside the zip file, the data for each thickness of aluminium is saved in a file with the thickness as its filename. 

Data is stored in data.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. The detector is run in Time Over Threshold mode, where it measures the charge for the amount of time it is above the threshold value.
