  4. Calorimeter Simulation Calorimeter Energy Resolution

  5. Photon Showers • Photon Shower Radii 5 GeV 15 GeV

  6. Photon Shower • Photon Shower Radii 50 GeV 75 GeV

  7. Photon Shower Radius

  8. Photon Showers • Reconstruction of Position from Energy Sharing

  9. Photon Shower • Position Resolution when Tiles are not Offset

  10. Photon Resolution • Position Resolution when Tiles are Offset

  11. Photon Showers Point Resolution Near Center of 5 cm Tile Tiles not offset Tiles offset

  12. Photon Showers Space Resolution within +-0.5 cm from the center (5 cm Tile) Tiles are not offsetTiles are offset

  13. Photon Showers • Position Resolution within+- 1.0 cm of Center ofTile (5.0cm) • Tiles are not offset Tiles are offset

  14. Resolution Improv. in 

  15. 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.

  16. 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.

  17. 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
