Designing a High Throughput Sample Holder for X-ray Transmission Diffraction Methods
X-ray transmission diffraction (XRD) performed at a high energy. X-ray radiation facilities like SSRL is a powerful tool used by researchers in a broad spectrum of fields to gather information about the atomic and molecular structures of many substances. The current XRD sample holder allows only one sample to be mounted at a time which means that each time a sample needs to be changed a user must undergo the rather elaborate and time consuming process of disabling the beam, unlocking the lead lined safety hutch, changing the sample, clearing and locking, the hutch, and finally re-enabling the beam. The objectives to create a sample holder that can accommodate as many as twenty-four samples and which can translate between those samples at a computer command so that a researcher can change sample from a computer terminal without having to enter the hutch.
