Hi Deuterium lamps can ionize air: http://www.ebay.com/sch/i.html?_trksid=p5197.m570.l1313&_nkw=Deuterium%20arc%20lamp&_sacat=0&_clu=2&_fcid=192&_localstpos&_stpos&gbr=1 The special thing with it is that air begins to be ionized with radiation shorter than 159 nm. So with this lamp you can do special things. Ionized air becomes senitive to MHD. It can become a waveguide for other types of radiation. It might dampen some type of radiation.
Maybe someone at this list can buy and maybe show some special effect? It is also very dangerous to live tissue. Be careful. David
