Hand-Held X-ray Fluorescence Materials Analyzer Al Kandziorski & Jamie Blowers (TD) 07-Feb-2011 All Experimenters’ Meeting
Outline • Purpose/background • Details • X-rays and ES&H • Example use cases • Demo AEM, 07-Feb-2011
Purpose/background • In the business of fabricating HEP devices we have found a need for being able to perform material identification • Analytical equipment historically has been very expensive (e.g. SEM) • Historically we’ve had to rely primarily upon certifications, visual, and indirect measurements (e.g. permeability) AEM, 07-Feb-2011
Purpose/background • We recently found that handheld technology has become more affordable, so in FY10 we set aside some $ • We reviewed three bids (Oxford, Thermo-Fisher, Bruker). Bruker met all our requirements and was by far the most competitive for price and warranty. • Took delivery of a “S1 Turbo LE” XRF Alloy Analyzer in October 2010 AEM, 07-Feb-2011
Details • The unit has a 4-watt X-ray source • Voltage ranges from 10 – 40 kV • Current ranges from 0.05 – 60 µA • Silicon Drift Detector (has its roots in HEP) • Capable of measuring elements as light as Mg AEM, 07-Feb-2011
Radiation Safety • A RWP is required • Radiation profile: Recall that the average annual dose is 360 mrem, and the Fermilab-imposed annual limit for Rad Workers is 1500 mrem. AEM, 07-Feb-2011
Example use cases • Looking for lead in paint on a SCRF cryomodule • Verifying that a weldment is made of the correct grade of SS • Identifying materials which were mislabeled (and all look the same but they are different alloys) AEM, 07-Feb-2011
Demo AEM, 07-Feb-2011
