摘要
We have constructed charged particle detectors using high quality CVD diamond. We report here the measurements of a diamond-tungsten sampling calorimeter and a diamond microstrip detector. The energy response and resolution (sigma(E)/E) of the calorimeter were measured using an electron beam of energy 0.5 to 5.0 GeV, and compared with those from a silicon calorimeter of similar construction. We find sigma(E)/E = (4.7 +/- 2.7)%/E + (19.13 +/- 0.86)%/ square-root E (2.3 +/- 1.8)% for the diamond-tungsten calorimeter, where + indicates addition in quadrature, which is in good agreement with our result of sigma(E)/E = (3.89 +/- 0.87)%/E + (19.73 +/- 0.19)%/square-rootE + (0.0 +/- 1.6)% for the silicon-tungsten calorimeter. The CVD diamond microstrip detector consists of 50 mum wide strips on 100 mum centers. A signal-to-noise ratio of 6:1 and a position resolution of 25 mum was observed during recent accelerator tests.
