Imaging soft X-ray microscope at Rits Synchrotron Radiation Center

Area of Science:

• * Advanced microscopy techniques
• * X-ray imaging and optics

Background:

• * Traditional X-ray microscopy often requires samples to be in a vacuum.
• * Observing biological specimens in their native state (e.g., hydrated) is challenging under vacuum conditions.
• * Existing optical systems may limit the resolution achievable in soft X-ray microscopy.

Purpose of the Study:

• * To introduce a newly installed imaging soft X-ray microscope at Rits SR Center.
• * To enable the observation of biological specimens in an air environment, avoiding vacuum disruption.
• * To enhance the resolution capabilities of soft X-ray microscopy through optical system redesign.

Main Methods:

• * Installation of an imaging soft X-ray microscope utilizing zone plates.
• * Specimen mounting in an air environment, compatible with the microscope.
• * Utilization of an optical microscope for pre-focusing specimens.
• * Design and implementation of a novel optical system.

Main Results:

• * Successful operation of the soft X-ray microscope with specimens in air.
• * Observation of both dry and wet biospecimens without breaking the microscope's vacuum.
• * Demonstrated feasibility of in-situ observation of biological samples.
• * Achieved improved resolution due to the new optical system.

Conclusions:

• * The developed soft X-ray microscope facilitates in-situ observation of biological specimens in air.
• * The system's ability to maintain atmospheric conditions simplifies sample preparation and observation.
• * The redesigned optical system contributes to enhanced imaging resolution.
