cooling of the coils.
Everything has to be checked as leak-proof. Once the sensors and measuring
cables are installed, the first module can leave the assembly rig - after a
scheduled total construction time of 28 weeks.
In the experimentation hall Transported into the experimentation hall on a
special carriage, the module is hoisted onto the assembly rig and into the
bottom shell of the outer vessel; connections and supports are attached. The
120-ton component is now lifted onto the actual machine foundation and
additionally provided with auxiliary supports. The top shell of the outer
vessel is put on and brazed. Sixty ports connecting the plasma and outer
vessels through the cold coil region now have to be incorporated together
with their thermal insulation.
Now come the in-vessel components, particularly the numerous parts of the
divertor. The plates will remove impurities and some of the thermal energy
from the plasma. The remaining energy is taken up by the wall protection
comprising steel panels and a heat shield clad with graphite tiles. The
fivefold symmetry of the device is repeated in the divertor: The two times
five divertors are composed of divertor plates and guide plates, regulating
coil, and cryopump with the necessary piping. Many of the components,
including pumps, heat shield, and divertor modules, are now being built in
the Central Technical Services division of IPP at Garching; the divertor
plates, regulating coils, and steel panels are being manufactured by
industry. The acceptance tests are also under way at Garching: These concern
the leak and degassing rates of the components and the loading capability of
the divertor components at high heat fluxes.
By the time all five modules have been installed in the experimentation hall
the work steps taken hitherto will have been performed five times. Finally,
the five major components have to be joined: The brazing seams of the plasma
and outer vessels have to be closed, and the magnets have to be connected to
the power and helium supplies. This will be followed by the main power
connections, cooling pipes, and repeated control measurements and leak
tests: The basic machine will then be complete.

Hey RC,
You may have to repost; I'm getting a 403 forbidden error on the link, even
the root domain rejects requests. Can you cut and paste the story?
