COSRAY – Detecting Neutrons in Antarctica

One of the hidden gems at McMurdo, in terms of science experiments, is the COSRAY Neutron Detector. I had the opportunity to go inside the current COSRAY Building at McMurdo, led by technician James Roth.

More on COSRAY, from UNIVERSITY OF DELAWARE BARTOL RESEARCH INSTITUTE NEUTRON MONITOR PROGRAM :

A neutron monitor is an instrument that measures the number of high-energy particles impacting Earth from space. For historical reasons these particles, mostly protons and helium nuclei, are called “cosmic rays.” Because the intensity of cosmic rays hitting Earth is not uniform, it is important to place neutron monitors at multiple locations in order to form a complete picture of cosmic rays in space. Bartol Research Institute currently operates 8 neutron monitors.
