IME, not really, but it will depend on the individual. The group I'm working with is currently designing a new tokamak. While the design of this machine is being done almost entirely from within the group, with some outside help from a couple of other groups with tokamaks similar to what we...
One of the major problems in magnetic confinement devices is the actual confinement of energy and particles. The energy confinement time is typically observed to be much less than that required to be able to have a fusion power gain greater than unity. This confinement time is much lower than...
Actually, they've discontinued the use of that meaning. It is now meant to be ITER as Latin for "the way". Apparently "thermonuclear" makes some people uncomfortable. Strange.
AFAIK, JT-60U has the has the record for the highest fusion triple product, the record for the highest central ion temperature and the record for the largest equivalent Q (1.25). The other machine close to JT-60U is JET, both of which are considerably larger than HT-7.
I wonder what that was filmed with. I know that NSTX has a camera that was built by the Princeton Scientific Instruments that can record at 1 million frames per second. :eek:
Here are some more videos from NSTX. These aren't with the "super camera", but are with another one of their other...
I read this article a while ago and we have a professor here who has some ties to this reactor. The $40 million is for an upgrade to the HT-7 tokamak, not for a new machine. The article was quite misleading about this. IIRC, the upgrade is to install superconducting poloidal field coils...
Additionally the colour of the star is determined by the surface temperature and is pretty well modeled as a black body. Cooler stars are towards the red end of the spectrum and hotter stars the blue.
Electrons moving through the air strike the molecules in the air, heating them up. In the case of a spark there are a lot of electrons causing a lot of heating. The air expands rapidly and then once the electrons stop heating the air cools rapidly and "snaps" back together. The sound you hear...
Computational physics has applications to pretty much all research going on in physics. Typically you can use more complex models to compare with experiment by using computer simulations. I'm doing stuff like this right now involving some probes on a tokamak. The situation in the vicinity of...
Sure we do. I don't think that we're so used to it that we don't notice it, it is more that the force acting on a person is so much smaller than the force due to the Earth's mass that we don't notice it. You could calculate the force straightforwardly and if there's a sensitive enough...
The best way to think about it I find is that it isn't a particle or a wave. It simply appears to be more wave-like or particle-like depending on the experiment. The same thing is true of particles also. There are experiments where electrons behave like waves. My opinion is that the...
You can buy plenty of magnets. I'm personally not aware of where you can buy them locally, but ebay tends to have a lot of all shapes and sizes. Hobby stores might have some. You can buy very strong magnets. So strong that they are dangerous and could result in severe injury or even death in...
