Design and Principles

This design of the cosmic ray telescope (CRT) was developed by Dr. Joseph Guth in 2005. It has been undergoing testing and evaluation with several upgrades since. It utilizes two matched ionization detectors linked with highly matched circuitry through a specialized coincidence counter. Each time an ionizing particle passes along the axis through the two detectors within a specific window of time, a count is registered on the monitoring computer. The current CRT has an angular resolution of 2 degrees. This is useful for the first types of studies being conducted with it, that of mapping the entire sky for sources of cosmic rays falling within the energy range of approximately 10^14 to 10^20 electron volts.
