5/20/2026 Appendix “B” Argonne National Laboratory Statement of Work Microwave Resonant Cavity System Compatible with Advanced Photon Source Beamlines Background Argonne National Laboratory (ANL) seeks to acquire a microwave-assisted heating system for in-situ X-ray experimentation at the Advanced Photon Source (APS). The system shall utilize a TE111 microwave resonant cavity operating in the 2.4–2.5 GHz frequency band to control the heating of solid samples during synchrotron X-ray interrogation.

The system will serve as a research platform enabling controlled microwave-material interaction studies under APS beamline conditions. The cavity geometry, beamline apertures, and sample-positioning interfaces shall be compatible with APS experimental configurations for high-energy diffraction and tomography, as well as rotating sample-stage assemblies. The system shall include sight access with X-ray-transparent windows positioned perpendicular to the sample position, and bottom access for sample insertion while maintaining free rotation of the sample connected to the existing APS beamline stage.

The system shall support programmable temperature profiles, closed-loop PID control, synchronized data acquisition, and integration with APS beamline experiments. The resonant cavity system is intended for research use and shall provide user-accessible control interfaces and data logging capabilities suitable for experimental development and analysis.

This contract covers the design, fabrication, testing, delivery, and optional installation support of a fully integrated microwave resonant cavity heating system for operation at Argonne National Laboratory’s Advanced Photon Source.

The vendor shall provide all hardware, control electronics, microwave power delivery equipment, software, instrumentation, documentation, and support necessary for standalone operation of the microwave heating system.

The base system shall include:

Scope microwave resonant cavity with APS beamline access ports and provisions for X-ray-transparent windows Windows-based control computer with installed python or LabVIEW-based control software Manual translation mechanism for positioning the cavity over the sample holder Objectives Water-cooled cavity plate and associated cooling provisions Motorized cavity translation system X-ray transparent cavity windows Tasks Water chiller for microwave generator and/or cavity cooling The primary objective of this procurement is to obtain flexible and research-capable microwave heating chamber components suitable for in-situ APS experimentation.

The system shall:
