HQEPD dark noise |
|
|
Dark noise measurement for 6 HQEPDs and 1 C30665. All of these showed sufficiently low dark current noise levels compared with the noise level of the DCPD preamp. The measurement was limited by the input noise (ADC) noise of the FFT analyzer as the line noises were too big.
The measurement has been done with the transimpedance of 1e7. The bandwidth of the measurement was 50kHz. |
