Japanese researchers synthesize elusive atomic element 113
A Japanese team from the RIKEN Nishina Center for Accelerator-based Science (RNC) has announced the synthesis of the elusive atomic element 113.
Currently known as ununtrium, which means one-one-three, the element with 113 protons does not occur in nature.
Searching for superheavy elements is a difficult and painstaking process because they must be produced through experiments involving nuclear reactors or particle accelerators, via processes of nuclear fusion or neutron absorption.

KSTAR aims for longer plasmas
At the Korea Institute of Fusion Energy (KFE), the KSTAR tokamak recommenced operations in December after a major upgrade to replace the device's carbon divertor with a tungsten divertor.
According to an article on the KFE website, the original carbon divertors could take a thermal load of 5MW/m², whereas the tungsten divertor can take 10MW/m². The upgrade is critical to the goal of sustaining a 100-million-degree plasma for 300 seconds by 2026. Data from the operational campaign will be directly relevant to ITER, which will operate a tungsten divertor under similar plasma conditions in terms of shape and structure.
This testing campaign will continue through February 2024. Read more about the plans in this article in English on the KFE website, or in Korean in the Chosun Biz.
