Description

In this work, we have explored the potential of oxygen capturing in Liquid Argon (LAr) of the innovative CuO dispersive layered double hydroxide media (R-LDH). Low temperature experiments in the LAr Purification Cryostat (PuLArC) at IFGW/Unicamp were performed using LAr circulation through two filters, one containing the R-LDH material and the other the BASF commercial copper material (Cu-02265 - proposed as a reference O_2 getter media by Fermilab) for comparison. Interestingly, the experiments performed in PuLArC revealed that the R-LDH innovative media was capable of capturing O_2 from recirculating LAr in PuLArC, reducing the O_2 contaminants concentration to 80% of its initial values after 200 min of LAr circulation. As for the reference media BASF Cu-S0226, this media reduced the O_2 concentration to 40% of its initial value in the same time window. This result demonstrated a putative higher potential of the innovative R-LDH media for O_2 capturing in LAr and invoke further tests of this media in the PuLArC and in larger scale LAr cryostats, possibily at Fermilab and CERN.
