Description
The ArDM experiment is designed for direct detection of WIMPs. In 2015, the experiment was commissioned in the single-phase mode at the target size of nearly 1 tonne. The results confirmed the performance and low background behavior of the installation and gave a promising perspective for the planned double-phase runs. Crucial information was derived from the data: the existence of optical-active impurities in the liquid argon, causing the scintillation light attenuation. We discuss results from the data analysis: detector performances, backgrounds, pulse shape studies, and hardware upgrades. Further-on we present activities for DS20k development: exploiting the ArDM infrastructures for tests of light detection modules and qualification of depleted argon batches.
