My Project: Research on the effect of cosmic radiation at different latitudes using HiSPARC detectors

Pip Rudge • Studying Maths, Physics, Psychology & Theatre Studies. • Enjoy athletics and drama. • Future - Physics at University.

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 1 st hypothesis – As latitude increases the number of cosmic ray events will increase. My 2 nd 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. 18000 Neth Leide - 340 16000 Neth Eind 14000 Tilbu Neth Leide 12000 Midd 3201 Neth 10000 Leide Zwijn 3104 8000 Neth Leide 6000 Neth Amst 4000 Zaan Neth 2000 Amst Hoor 0 Denm 3 3 3 3 3 3 3 3 3 3 3 3 3 - 200 1 1 1 1 1 1 1 1 1 1 1 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 2 2 2 2 2 2 2 2 2 2 2 2 2 / / / / / / / / / / / / / 1 8 5 2 9 6 3 0 7 3 0 7 4 / / 1 2 2 / 1 2 2 / 1 1 2 6 6 7 8 / / / / / / / / / 6 6 6 7 7 7 8 8 8
