    4. Words of WelcomeAlfred Reinhold … X-RAY WorX is a group of highly experienced and competent experts, partly working in this business from the very beginning of microfocus technology. As the founder of the former company Feinfocus, that introduced the first microfocus X-ray system for industrial application with focal spot sizes below 5µm, I highly appreciate the pioneering spirit of the young team of X-RAY WorX… Alfred Reinhold,Pioneer of Microfocus X-ray Technology (February 2010) Source: http://www.alf-reinhold.de/

    28. Rod anode technology • Widespread application in • Aerospace industry • Tank and pipeline construction • Casting industry • NDT at inaccessible places • Engines • Hollow chamber profile elements • Pipes and tanks • Different targets and beam geometries • Exchangeable radiation heads

    29. Rod anode technology • Standard rod anode • Target cooling with external cooling liquid feeding • Inconvenient handling • Insufficient cooling of the O-Ring sealing • Unstable vacuum during continuous operation

    30. Rod anode technology • Rod anode with internal cooling • Internal cooling channel • Effective cooling of the O-Ring sealing up to 100W • Easy handling

    31. Rod anode technology • Application advantage • External cooling • Limited penetration depth • Internal cooling • Optimized usage of the penetration depth

    32. Application advantage • Radiography of only one wall thickness • Better localisation of material defects • Better detail recognition
