Portable and Adaptable Neutron Diagnostics for Advancing Fusion Energy Science Addendum

Year: 2025

Type: report

Abstract: Activation detectors developed at LLNL for measuring real-time neutron fluence from fusion sources are used in the broader fusion community. The recommended fluence operating range of this diagnostic is 5x102 – 1x106 n/cm2. The upper limit on this fluence range is set by the dead time caused by data transfer between the detector and data acquisition computer. Delaying the start of counting is a possible strategy to operate these detectors in higher fluences.
