Web6 de abr. de 2024 · To measure the sample phase, the X-ray diffraction (XRD) measurement was conducted with Cu K α radiation at room temperature (the bandwidth is 0.017°, modulation is 0.088°). The result presented in Figure 1 shows diffraction peaks at 35.7° that are associated with the (0004) Bragg reflection, which has been measured in … WebIn a Geiger-Müller tube, or Geiger counter, incoming X-ray photons ionize atoms in a gas-filled volume. An applied high voltage induces further ionizations from collisions between liberated electrons and neutral atoms, creating an avalanche of charged particles and a large electrical pulse that is easily detected.
