Multiple vacuum chambers for the insertion devices with 1-mm wall thickness were developed at Argonne for the APS and many other synchrotron radiation facilities.* Using the extrusion for the insertion device vacuum chamber (ID VC) for the DESY FEL project with a 9.5-mm inner diameter, we decreased the wall thickness to 0.6, 0.5, and 0.4 mm to test the vacuum integrity for a thin wall in these extrusions. A special ultrasonic transducer with a 1/8" diameter was required to do the job. Also some additional short samples, machined exactly as the experimental piece, were used to verify wall thickness mechanically. Experimental setup and test results are presented. * Trakhtenberg E., Wiemerslage G., Den Hartog P.
