Recently, a custom-built in-situ tensile heating-cooling stage developed by GoGo Instrument for a domestic technology company has been delivered and officially installed at beamline BL16B1 of the Shanghai Synchrotron Radiation Facility (SSRF), where it has now entered experimental service.
This device is custom-developed for synchrotron radiation in-situ characterization, enabling coupled temperature and mechanical tensile testing. It meets the beamline's requirements for high precision, high stability, remote operability, and compatibility with the EPICS system.
The delivered in-situ tensile heating-cooling stage operates over a temperature range of –190 °C to 400 °C. Based on the customer’s experimental needs, several customized features have been implemented in terms of mechanical parameters, on-site adaptability, and system control. Key performance parameters and functions are as follows:
01 Large tensile force and long stroke for testing high-ductility materials
The device is equipped with a high-precision tensile drive unit, providing a maximum tensile force of up to 500 N. This covers the mechanical testing needs of most samples, including films, polymers, and flexible composite materials. To address the experimental challenges posed by high‑toughness and high‑elongation materials, the device features a custom 110 mm ultra‑long tensile stroke, which fully captures the entire deformation process of the sample – from stretching, creep, and yielding to fracture. This allows faithful reconstruction of the structural evolution of materials under large deformations, meeting the in-situ characterization requirements for realistic working conditions.
02 Custom structure adapted to the Shanghai Synchrotron Radiation Facility beamline
Tailored for the on‑site installation space, height standards, and optical path layout of the SSRF BL16B1 beamline, the device features a custom mounting bracket. The overall dimensions and installation height are fully compatible with the on‑site conditions, enabling rapid alignment, optical path matching, and device fixation – thus fitting the beamline's standardized experimental procedures.
03 EPICS‑compatible for beamline integrated control
The software control system has been custom‑developed to be compatible with the synchrotron EPICS control system. All functional modules of the device – temperature regulation, tensile displacement, force loading, etc. – can be uniformly driven, interactively controlled, and remotely adjusted under the EPICS system. This achieves synchronization of mechanical loading, temperature variation, and X‑ray acquisition, ensuring the integrity and accuracy of in‑situ experimental data.
04 Integrated cabinet for experimental efficiency and ease of maintenance
The device adopts a custom modular integrated cabinet design, highly integrating core auxiliary equipment such as the temperature controller, refrigeration controller, recirculating chiller, and liquid nitrogen tank. This integrated structure enables rapid installation and quick stowage, significantly reducing pre‑experiment setup and post‑experiment cleanup time, thereby improving beamline experimental turnover efficiency.
