What are cosmic rays? What is HiSPARC? My Objective – To find out if there is a link between latitude and the number of cosmic ray events and if so, why?

My 1st hypothesis – As latitude increases the number of cosmic ray events will increase. My 2nd Hypothesis – The reason for this effect would be due to the Earth’s magnetic field.

Reading background articles:

Cosmic rays Data analysis

Practice analysis:

Winter-Summer variation Day-night variation Effect of pressure

Preliminary Analysis:

• Compare the difference between day

and night at different latitudes.

• Different detector sensitivity.
• Analysed data from detectors with

lowest and highest latitudes.

• Difficult to find a suitable hypothesis.
• Discussion with Cristina Lazzeroni.
• Normalising data.
• Voltage of detector - doesn’t make

significant difference.

Main Analysis:

• Investigate the total number of cosmic

ray events.

• 15 stations.
• July.

Possible Reasons:

• Sun’s Radiation
• Earth’s magnetic field

• Only used data at night.
• Found a correlation of 0.4248.
• Further research needed.

• Plotted a graph of the number of events each

day against latitude for 7 stations for 3 months – June, July and August.
