Description
Astrophysical and cosmological observations unambiguously established the existence of non-luminous but abundantly present Dark Matter, which interacts gravitationally. Among various models, Weakly Interacting Massive Particles (WIMPs) are the most popular and well-motivated candidates.
I shall first present a new detector technology, named Snowball – Chamber - its design, involved DAQ system, physics motivation and our progress so far. The target material is highly purified (20 nm filtration) supercooled water. Our previous run studies have shown direct evidence of nucleation of the target by neutrons, which caused a + 0.7 °C warmer freezing point on average than the control with a statistical significance > 5$\sigma$. Currently, we are improving the system to overcome the pitfalls we faced in the 1st run. So next, I shall discuss my upgraded 3D model of the Detector and improved Geant4 simulation models which are underway and will show the results of the calibration runs using RTDs and Thermocouples. This presentation will contribute to this unique technology with future scopes and possibilities across fields.
