Leibson's Law: It takes 10 years for any disruptive technology to become pervasive in the design community. This blog is about the disruptive technologies that either have or will win over electronic engineers, some that won't, and why. Written by Steve Leibson, Tensilica's Technology Evangelist.

It’s Always the Connectors 3: CERN's LHC Won’t be Spitting out any Black Holes Until Next Year

Last December, I was writing about failing connectors on the Space Shuttle’s main tank sensors (here and here). Once brought down to cryo temperatures, the sensor feed-through connector in the main tank failed. Guess what? The same thing has happened to CERN’s Large Hadron Collider (LHC). This Associated Press report on ABC (Bad Connection Caused Atom Smasher Shutdown) describes how a failed connector caused a superconducting magnet to “quench,” overheat, burn a hole through the insulation, and let out about a ton of liquid helium coolant. For those of you worried that the LHC was going to create a black hole that ate the earth (previously discussed here and here), you now have a reprieve until May of next year. That’s how long it will take to warm the LHC up, repair the damage, and cool the LHC back down.

What we need is a new national movement to address "Why Johnny Cannot Make High-Reliability Electrical Connectors, Fasteners, and Wiring." It's time to re-invest in our educational system. We've got an educational workforce that has never crimped _or_ soldered. Chinese and Russian children are spending their days learning such skills! America cannot afford a solder gap! On the other hand, I'm going to enjoy this temporary reprieve from being reduced to infinite entropy.

Funny Dave, in a Strangelovian way, but the people who made those original connections at the LHC were French and Swiss, I believe.

Yeah, the Euro-ness of the LHC sort of wrecks the joke. I try, though, I try. :)
