LaB6 is the chemical formula for a substance called Lanthanum Hexaboride. I critical component used in hallow cathode assemblies for hall effect thrusters. Since barium impregnated tungsten is a depleting source of electrons over time, LaB6 is often preferred. Just don’t touch the stuff, and I quote “may cause writhing, walking on toes with arched back, ataxia…” etc.
Anyway, getting to the point. I need some for an emissive electrode I’m trying to build. So I googled it. To my surprise Lab6 is also a very popular, very addictive Atari like game. Head to www.lab6.com and you’ll see what I mean. I highly recommend it. … the video game that is. Not to say that emissive cathode’s aren’t fun, they’re just not everyone’s ‘cup of tea’. I sort of lost 20 minutes of the day when I found this.. oops.
