摘要：
We present noise data measured from a Ti/Au transition-edge sensor that is coupled via a dot matrix to a Cu/Bi absorber. The observed noise properties can be explained by a combination of excess white noise and internal thermal fluctuations. Quite unexpectedly, the excess white noise level goes down if one biases the sensor deep enough in the transition.
