First measurement results from DANAE - Demonstrating DePFET RNDR on a prototype Matrix
In the search for dark matter particle candidates, the mass region below 1 GeV/c$^2$ is relatively unprobed. Utilizing a low-noise silicon sensor as a sensitive target material, we aim to study the event signature of recoils between dark matter candidates and bound electrons. As the deposited energy...

| Summary: | In the search for dark matter particle candidates, the mass region below 1 GeV/c$^2$ is relatively unprobed. Utilizing a low-noise silicon sensor as a sensitive target material, we aim to study the event signature of recoils between dark matter candidates and bound electrons. As the deposited energy is only a few eV, a sensor capable of detecting these low signals is required. We present first measurements on a prototype pixel matrix. It is based on the RNDR DePFET principle and provides a deep sub-electron readout noise of 0.2e$^-$ and below. |
