UVa Physics: LEGS-TPC

Circuit Section These pictures show a section of the double-sided, copper-clad kapton used to define the inner gradient rings for the time projection chambers (TPC) of the SASY detector at LEGS. The resistors are 1-2 M ohm. The detector will be used in experiments testing the Drell-Hearn-Gerasimov Sum Rule (DHG).
