Relation among Potential, Fluctuation Change and L-H Transition in the JFT-2M Tokamak
Potential and density/temperature fluctuation at L-H transition are measured by the heavy ion beam probe (HIBP) on JFT-2M. It has been observed that the time scale of potential change is as fast as 10-100μs when the input power (Pin) is larger than the L-H threshold power (P th). When Pin~Pth, the confinement is improved gradually step by step with sawteeth crashes accompanied with the decrease...
متن کاملIn situ "artificial plasma" calibration of tokamak magnetic sensors.
A unique in situ calibration technique has been used to spatially calibrate and characterize the extensive new magnetic diagnostic set and close-fitting conducting wall of the High Beta Tokamak-Extended Pulse (HBT-EP) experiment. A new set of 216 Mirnov coils has recently been installed inside the vacuum chamber of the device for high-resolution measurements of magnetohydrodynamic phenomena inc...
متن کاملAn in-situ infection detection sensor coating for urinary catheters
We describe a novel infection-responsive coating for urinary catheters that provides a clear visual early warning of Proteus mirabilis infection and subsequent blockage. The crystalline biofilms of P. mirabilis can cause serious complications for patients undergoing long-term bladder catheterisation. Healthy urine is around pH 6, bacterial urease increases urine pH leading to the precipitation ...
متن کاملEffects of wall boron coating on FTU, an all metallic and carbon free medium size tokamak
Boronization of FTU tokamak strongly affects its gas recycling, impurity concentration and its temporal evolution. Two main phases are distinguished. In the first one, lasting about 60 discharges, with the machine fully boronized, the radiation losses decrease from 80% to 40% and the impurity content drops from Zeff = 6 to Zeff ≈ 1.5 at n̄e ≈ 0.35×1020 m−3 in ohmic conditions. In the second phas...
متن کاملA method for in situ measurement of the elastic behavior of a columnar thermal barrier coating
The mechanical behavior of a ceramic coating and the evolution of this behavior in-service play crucial roles in governing the performance and lifetime of these materials. A protocol is presented that allows for characterization of the in-plane elastic modulus and strain to failure of fragile ceramic coatings. The protocol employs digital image correlation (DIC) to measure time-resolved, full-f...
