ITER Vacuum Group introducing "Gas Roulette"

It may look like play, but the latest model produced by the EU checking out the complex gas routes around the ITER divertor takes about one day of high speed computer time to run. The ITER Vacuum Section is thus working on a proposal for a more accurate model which will allow optimizing the design of components in the divertor region for compatibility with the vacuum pumping. The new model is likely to take four days to run giving plenty of time for others to try a game of "Gas Roulette".
