The cell structure consisted of a cap, anode, separator, cathode, spring, and case. The coin cell (CR2032) with an OD of 20 mm was used. To assembling the cell, an anode (Li foil, 0.75 mm thickness), separator (Celgard2400, 25 μm thickness), cathode (LFP) and spring (stainless steel, 0.3 mm thickness) were provided. Since the case and cap were made from stainless steel, they did not allow x-ray transmission. Thus, the aperture with OD 8 mm and sealed with Kapton film were provided.

If you have any questions or require additional information, you are encouraged to contact the BL8 beamline staff for assistance.
Access routes
Standard Access
Synchrotron Thailand runs three main Calls for Proposals each year. Proposals submitted via this route are evaluated by an independent peer review panel and successful applicants are allocated beamtime in the regular schedule. We strongly recommend contacting BL8 beamline staff before submission to discuss feasibility and the most suitable experimental configuration.
How to apply: submit your proposal through the official user application system and follow the deadlines listed on the Synchrotron Thailand website. For pre-submission advice, contact the Proposals Office.
Rapid Access
Rapid Access is intended for short, urgent, or time-sensitive ex-situ experiments for example, proof of concept measurements or quick data required for responding to referees. Rapid Access requests are considered outside the main Calls and are assessed on a case by case basis.
How to apply / who to contact: contact the Head, X-ray Spectroscopy section or beamline staff prior to submitting a Rapid Access request so the team can advise on feasibility and prioritisation. All Rapid Access applications must be submitted through the user application system.
Beamline Submission Process
All procedures can be found in the following document. Click to download
Failure to submit the End of Experiment Feedback and/or the Experimental Report within the specified timeframe will be taken into consideration during the review of future beamtime proposals. Proposals may not be approved if the required reports from previous experiments have not been submitted.
