A cosmic ray detector telescope for use in informal and formal education settings
2007
We have developed an orientable
cosmic raytelescope based on scintillating tile and waveshifting optical fiber technology for hands-on laboratory use and for interactive public displays. The device is sensitive to ionizing radiation and is composed of four individual scintillating tiles into which are embedded double-clad optical fibers doped with waveshifter dye. These fibers are coupled to
photomultipliertubes (PMT). The telescope is mounted on an adjustable (rotatable) structure to allow the measurement of the
cosmic rayrate as a function of angle relative to the
zenith. This motion is controlled by the user through a computer-controlled
steppermotor. The readout system allows data to be collected and
uploadedto the Web enhancing the interactive experience and for follow-up analysis.
