Activity Description:
|
In summer 1999, QuarkNet teacher Rick Dower studied voltage-current relationships in silicon vertex detectors for the upgrade of D-Zero. After establishing a LabView interface to test voltage and current, Dr. Dower moved the apparatus to the small accelerator at the University of Massachussets at Lowell for testing under neutron radiation. All data was recorded and delivered in graphical form as a D-Zero Note. In this lesson, students analyze V vs I graphs to determine the extent to which the silicon vertices are or are not ohmic and to determine the effect that neutron radiation has on a semiconductor device. |
