Project Delivery |Microscope Heating Stage H1500-SR Enabling In Situ SAXS/WAXS High-Temperature Experiments

July 4, 2026

In materials science, condensed matter physics, polymer processing, and related fields, in situ characterization of nanoscale structural evolution under extreme conditions is the key to unraveling microscopic mechanisms. Small-angle X-ray scattering (SAXS) probes electron density inhomogeneities on the scale of 1–100 nm, making it a powerful tool for studying nanoparticles, pores, phase-separated structures, and more. The high brilliance of synchrotron radiation sources enables real-time tracking of millisecond-scale structural changes in materials under external fields such as high temperature and mechanical stress.

Recently, We successfully completed a major delivery – supplying the synchrotron ultra-high-temperature hot stage H1500-SR to the SAXS Station (BL16B) at the Shanghai Synchrotron Radiation Facility (SSRF). This device will be integrated with the existing Pilatus 2M (SAXS) and Pilatus 900k (WAXS) detectors at the beamline, empowering users to conduct in situ SAXS/WAXS experiments on bulk/powder materials under ultra-high-temperature conditions.

Customer Requirements: In Situ SAXS/WAXS Characterization at Ultra-High Temperatures

The BL16B SAXS beamline at SSRF is one of the first seven beamlines built at the facility. The beamline is fed by bending magnet radiation from the storage ring and is equipped with a sagittally bent water-cooled double-crystal monochromator and a bent cylindrical mirror. Currently, BL16B serves SAXS research in polymer materials, nanomaterials, mesoporous materials, colloids, liquid crystals, metallic materials, and more, and has realized multi-method combinations including SAXS/WAXS/Raman/IR.

In user experiment scenarios, BL16B faces the following core challenges:

Ultra-high temperature demands: Studies such as ceramic sintering, metal heat treatment, and phase transitions in superalloys require in situ SAXS/WAXS experiments in the 1000–1500°C range to track real-time microstructural evolution of nanoscale pores, precipitates, grain boundaries, etc.
SAXS/WAXS optical path compatibility: Small-angle scattering measures weak signals near the main beam; the sample position must offer high X‑ray transmission, low absorption, and low background scattering. Simultaneously, sample position stability during heating must be maintained at the micrometer level to ensure accurate scattering signal alignment with the detectors.
Atmosphere control: Samples are highly susceptible to oxidation at elevated temperatures; inert/reducing protective atmospheres are essential for ensuring data authenticity.

The existing equipment at the beamline has limited temperature range: BL16B’s current Linkam hot/cold stages (e.g., THMS600) typically do not exceed 600°C, which cannot cover the higher-temperature in situ experiments – precisely the core value delivered by GoGo microscope heating stage.

Solution: GooGo Instrument Synchrotron Ultra-High-Temperature Hot Stage

To address the above needs, GoGo custom‑developed the microscope heating stage H1500‑SR for BL16B. The device adopts a resistive‑heating furnace‑type sample holder structure, and its design fully accounts for the stringent requirements of SAXS experiments in terms of high X‑ray transmission and low background scattering. Key parameters are as follows:

Parameter	Specification
Temperature range	RT – 1500°C
Max. heating rate	150°C/min
Heating method	Resistive heating, furnace‑type sample holder structure
Atmosphere control	Supports inert/reducing protective gas purging
Optical path compatibility	Synchrotron SAXS/WAXS transmission geometry
Sample holder	Standard φ8 mm (OD) × 2 mm (depth) ceramic groove holder + dedicated powder sample fixture
Beamline compatibility	Precision‑engineered structure ensuring high X‑ray transmission, low background scattering, and high sample position stability

Four technical highlights:

Highlight 1 – Broad temperature range with precise control, filling the ultra‑high‑temperature gap: Covering RT to 1500°C with a maximum heating rate of 150°C/min, the stage effectively overcomes the temperature limitation (~600°C) of existing hot/cold stages at BL16B, extending the beamline’s in situ variable‑temperature capability up to 1500°C and providing critical support for high‑temperature in situ SAXS/WAXS studies of ceramics, metals, superalloys, and more.
Highlight 2 – Custom‑designed for SAXS transmission geometry, ensuring high X‑ray transmission and minimal interference: The device is custom‑engineered for the high sensitivity required to detect weak scattering signals near the main beam in SAXS experiments. It comes with a standard φ8 mm (OD) × 2 mm (depth) ceramic groove holder and dedicated powder sample fixtures, compatible with perpendicular‑incidence transmission geometry. The sample holder is made of high‑temperature‑resistant ceramic, offering low X‑ray absorption, low background scattering, corrosion resistance, thermal deformation resistance, and non‑contaminating properties, ensuring structural stability and data quality at high temperatures.
Highlight 3 – Controlled atmosphere environment to prevent high‑temperature oxidation: The atmosphere chamber supports purging with inert gases (e.g., Ar, N₂) or reducing protective gases, continuously protecting samples during high‑temperature experiments to ensure that SAXS/WAXS data truly reflect the intrinsic nanoscale structural evolution of the material.
Highlight 4 – Deep integration with the beamline’s EPICS control system for unified temperature control and synchronized data acquisition, allowing users to conduct the entire in situ experimental workflow from the control room.

On‑site Delivery: Installation, Commissioning, and Training

We completed on‑site installation and commissioning at SSRF, and provided dedicated training on equipment operation, temperature program setup, atmosphere control system usage, and data acquisition in conjunction with the Pilatus detectors. This ensures that beamline researchers and users can quickly become proficient and independently conduct experiments.

The newly delivered Microscope Heating Stage H1500-SR will be officially integrated into the in situ experimental equipment portfolio of BL16B, complementing the existing Linkam hot/cold stage to cover temperature ranges from RT–600°C and 600–1500°C. It will support one‑stop in situ SAXS/WAXS experiments including nanoscale pore evolution during ceramic sintering, precipitation kinetics during metal heat treatment, and nanoscale structural changes during phase transitions in superalloys.
