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…

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

Rod anode technology

►Target cooling with external cooling liquid feeding

►Inconvenient handling►Insufficient cooling of the O-Ring

sealing►Unstable vacuum during

continuous operation

►Standard rod anode

Rod anode technology

►Internal cooling channel►Effective cooling of the O-Ring

sealing up to 100W►Easy handling

►Rod anode with internal cooling

Rod anode technology

► External cooling► Limited penetration depth

► Internal cooling► Optimized usage of the

penetration depth

►Application advantage

►Application advantage

► Radiography of only one wall thickness

► Better localisation of material defects

► Better detail recognition
