We present the measurement of a radio-frequency single-electron transistor that displays a very high charge sensitivity of 1.9 μe Hz at 4.2 K. At 40 mK, the charge sensitivity is 0.9 and 1.0 μe Hz in the superconducting and normal state, respectively. The sensitivity was measured as a function of radio frequency amplitude at three different temperatures; 40 mK, 1.8, and 4.2 K.
