Preventive and Software Maintenance of Zeiss 810 Ultra nano-CT 18 November 2025 C.1 Background

In support of its mission and customer programs, the Materials Response and Design Branch (MRDB) of the Army Research Laboratory (ARL) relies upon The Zeiss Xradia 810 Ultra X-ray Computerized Tomography (CT) Scanner which is a specialized instrument designed to combine a series of X-ray images taken from different angles and uses computer processing to create three–dimensional (3D) volumetric images of materials. This is a highly complex instrument whose hardware and software require regular maintenance in order to remain fully operational and meet performance parameters including a scan resolution down to a 16 nanometer voxel size. This ultra-high resolution requires extreme precision and routine calibrations to meet such fine feature detectability. The preventative maintenance service contract that is requested will be for a service contract period of one (1) base year along with one (1) option year. The Zeiss 810 Ultra X-ray CT Scanner is located at Aberdeen Proving Ground, Aberdeen, MD which is where performance will take place.
