Calorimeter-Arlington 2 • We have built a cosmic ray telescope7.6x7.6 cm • Plan to use 1.3 GeV Muons • Plan to Study • Light Collection Efficiency for a straight fiber • versus a curved fiber using Tyvek and using • 3M Super Reflector as a function of the distance • from the fiber.
Calorimeter-Arlington • Plan to Study • Fiber Readout with Avalanche PhotoDiodes; • study voltage stability, temperature stability; • light loss versus fiber length. • Study uniformity of response of various • photodiodes.
Calorimeter-Arlington • Cosmic Ray rate observed in Boulder is 2 • per cm per minute which is twice the expected rate at sea level. • We would like to build a calorimeter module to study the content of the cosmic rays atBoulder’s altitude while testing our concept of spatial resolution and while waiting for beam availability. 2
