PXIE beam absorber

This is an image of an electron beam on the surface of the PXIE MEBT absorber prototype. PXIE, the Project X Injector Experiment under construction at the Cryomodule Test Facility building, will test the most technically risky elements of the proposed Project X proton accelerator. One such element is a roughly 10-kilowatt beam absorber in the medium-energy beam transport (MEBT) line, which will intercept undesired beam bunches. A 1/4-size prototype of the absorber is being tested with an electron beam in MI-31 and is shown in the image above. Photo: Marty Murphy, AD
