Document Type and Number:
Japanese Patent JP2018013472
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a compact, light-weight, and stable x-ray spectrometer that minimizes heat influx into an overall system.SOLUTION: A measurement chamber (2) of an x-ray spectrometer (1) with a goniometer (3) for analyzing x-ray fluorescence radiation from a measurement sample (4) comprises; an incident opening for x-ray fluorescence radiation to enter the measurement chamber; a first goniometer arm (5) for holding and adjusting an analyzer crystal (5a); and a second goniometer arm (6) for holding and adjusting an x-ray detector (6a, 6b), where the incident opening is vacuum-sealed by way of a window (7). The measurement chamber includes a bearing block (8) for rotatably receiving and holding both of the goniometer arms, each goniometer arm being mechanically adjustable by means of a piezo-motor (15, 16) securely coupled to the bearing block or a drive plate of the respective goniometer arm.SELECTED DRAWING: Figure 1
