It's a vacuum!<br /><br />There are many of experiments on BEC-BCS crossover studies that have significantly lower temperatures than what one could get using LHe, even when one pumps on it. All the laser cooling experiments are way beyond what one could get at the LHC. So like I said, the LHC (or those magnets) is not even the coldest place on earth, much less, the universe.<br /><br />Zz.ZapperZhttps://www.blogger.com/profile/15861398273820851809noreply@blogger.comtag:blogger.com,1999:blog-34480619.post-88604050512773350662010-07-26T09:24:00.520-05:002010-07-26T09:24:00.520-05:001) In the segment you posted "superconducting...1) In the segment you posted "superconducting" is not mentioned. What are you referring to?<br />Also: CMS uses superconducting Niobium-Titanium, ATLAS even uses two superconducting magnets.<br /><br />2) The LHC ring (or at least the cooled part) is not the coldest place in the universe but most probably the largest place at a Temperature of or below 1.9 Kelvin.<br /><br />CheersUnknownhttps://www.blogger.com/profile/06321559534998764288noreply@blogger.com
