Production of xrays, rotating anodes Rotation of anode constantly brings fresh metal target are into focal spot, allows greater power Elements of xray diffraction , B.D. Cullity and S.R. Stock, input without excessive heating These tubes can operate at power levels 5 to 10 times higher than fixed focus tubes http://content.onlinejacc.org/content/vol44/issue11/images/large/401959X.2259.GR6.jpeg http://www.flickr.com/photos/10597538@N00/270206403/ http://members.chello.nl/~h.dijkstra19/page5 2.html

Synchrotron x rays ove p122 Dove, p122 Fundamental limitation of lab xray tubes is the maximum intensity is limited t ht i dt i i if f i it limitations of lab xray A) Heat to prevent overheating; xrays production is very inefficient Rotating anode helps but still has limitations B) Usable wavelengths are limited by target A Finer control of wavelength is needed in some applications ex) to get resonance wavelength needs to be near absorption edge nchrotron sources Synchrotron sources
