Polycrystalline thick diamond samples were selected for this work. Silver deposits were made on both faces of the sample to perform measurements in sandwich configuration. Studies in pulsed mode were performed by using a commercial Amptek Cool-X source, constituted by a LiTaO3 pyrolectric crystal and a copper target window. Pulse height distributions were carried out with a charge-sensitive preamplifier Ortec 142IH and a digital pulse processor multi-channel analyzer PX4 by Amptek. The detector is able to resolve two characteristic lines (Cu Kα and Ta Lα) only 90 eV apart: this feature suggests very good energy-resolving capabilities for X-ray spectroscopy.

Abstract
Polycrystalline thick diamond samples were selected for this work. Silver deposits were made on both faces of the sample to perform measurements in sandwich configuration. Studies in pulsed mode were performed by using a commercial Amptek Cool-X source, constituted by a LiTaO3 pyrolectric crystal and a copper target window. Pulse height distributions were carried out with a charge-sensitive preamplifier Ortec 142IH and a digital pulse processor multi-channel analyzer PX4 by Amptek. The detector is able to resolve two characteristic lines (Cu Kα and Ta Lα) only 90 eV apart: this feature suggests very good energy-resolving capabilities for X-ray spectroscopy.| File | Dimensione | Formato | |
