Zap Energy hits 37-million-degree electron temperatures in compact fusion device
Zap Energy announced April 23 that it has reached 1-3 keV plasma electron temperatures—roughly the equivalent of 11 to 37 million degrees Celsius—using its sheared-flow-stabilized Z-pinch approach to fusion. Reaching temperatures above that of the sun’s core (which is 10 million degrees Celsius temperature) is just one hurdle required before any fusion confinement concept can realistically pursue net gain and fusion energy.

The Coolant Purification System (CPS) together with the Tritium Extraction System (TES) and Helium Cooling System (HCS) are the principal auxiliary circuits of HCLL and HCPB TBMs to be tested in ITER. Among them, CPS is used to extract tritium from the cooling primary circuit as well as to guarantee the removal of gas impurities which could interact with structural material. Based on considerations in terms of safety, tritium accountancy and process control, instrumentation philosophy requires real-time tritium monitoring (which might be not very accurate) to control the processes in both TBM helium loops and special tritium accountancy procedure with regard to the interface with other sub-systems of the Tritium Plant. Furthermore, in addition to chemical speciation of the flow, the control of the process requires the measurement of other parameters such as flow rates, pressures and temperatures. For each monitored parameter, this paper describes the most suitable technologies, including a review of advantages, drawbacks and possible ways of improvement.
