My work on the flow and thermal analysis of the argon in the DarkSide-20k TPC is on the arXiv today: arXiv:2503.08468

Performing computational fluid dynamics simulations and heat transfer calculations, the paper assesses the prospects for argon purification and the reach of internal calibration sources within the massive underground argon volume of DS-20k. It also analyses the thermal conditions required for dual-phase operation and informs the optimal placement of liquid inlets and outlets in the TPC.

I’m so excited to finally share this with the community after nearly three years of on-and-off work on this topic!
