Disruption mitigation with high-pressure noble gas injection
High-pressure gas jets of neon and argon are used to mitigate the three principal damaging effects of tokamak disruptions: thermal loading of the divertor surfaces, vessel stress from poloidal halo currents and the buildup and loss of relativistic electrons to the wall. The gas jet penetrates as a neutral species through to the central plasma at its sonic velocity. The injected gas atoms increa...
متن کاملMHD Simulations for Studies of Disruption Mitigation by High Pressure Noble Gas Injection
The problem of disruptions is a major challenge for ITER which establishes engineering and operational limits. MHD simulations including radiation and atomic physics have the capability of extending results of mitigation experiments on present devices to accurate predictions for ITER. The role of MHD in cases where impurity penetration is shallow is seen in a series of Alcator C-Mod simulations...
متن کاملconsequence analysis of the leakage, ignition and explosion during high pressure sour gas injection process to the oil reservoir
there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
Gas Jet Disruption Mitigation Studies on Alcator C - Mod and DIII - D
High-pressure noble gas jet injection is a mitigation technique which potentially satisfies the requirements of fast response time and reliability, without degrading subsequent discharges. Previously reported gas jet experiments on DIII-D showed good success at reducing deleterious disruption effects. In this paper, results of recent gas jet disruption mitigation experiments on Alcator C-Mod an...
متن کاملSolution of protein crystallographic structures by high-pressure cryocooling and noble-gas phasing.
Room-pressure flash-cryocooling of protein crystals is the standard way to reduce radiation damage during data collection. Typically, it is necessary to find cryoprotection conditions by trial and error, a process that is not always successful. Recently, a new method, high-pressure cryocooling, was developed that does not require penetrative cryoprotectants and typically yields very high qualit...
