NEW LIQUID NITROGEN FILLING SYSTEM
Many of the gamma-radiation detectors at iThemba LABS need to be kept cold using liquid nitrogen to achieve operating conditions. A new filling system has been developed over the last few months to replace the aging system that has been running for over a decade. On Wednesday 21 June the new liquid nitrogen filling setup was commissioned and has since reliably filled the AFRODITE detectors in the array. Over the next few weeks it will be closely monitored and improved if the need arises.
This new system has been optimized and is expected to lead to approximately 30% saving in our liquid nitrogen consumption. Looking into the future, this new infrastructure will be able to accommodate up to 40 detectors and will allow for easy implementation of the first batch of new detectors which will arrive later this year.
