200 kg of Underground Argon - The Struggle for Radiopurity


  • Mr. Gary FORSTER

Primary authors



Argon is a very useful element for modern scientific endeavors, but its naturally occurring isotopes make it too 'noisy' for low-energy applications like Darkside-50's Dark Matter search. The struggle to produce argon that is free of radioactive isotopes has a decade of rich history, and much of efforts took place at the Proton Assembly Building (PAB) at Fermilab. This talk will address the physics of the many steps of argon purification, as well as some of the historical aspects of the personnel involved in the efforts.
