Application of a single-crystal CVD diamond detector for simultaneous measurement of ions and X-rays from laser plasmas

摘要

A single-crystal chemical vapor deposition (CVD) diamond detector (DD) of a sandwich structure was used for the measurement of soft X-rays and ions emitted from plasmas obtained with the use the PALS laser system in Prague. The detector was fabricated in the Institute of Nuclear Physics PAN in Cracow with the use of diamond material obtained from Element Six, Inc. In the laser experiment, the responses of the detector to X-rays and ions were compared with the responses of an ion collector (IC). The signals from the DD proved to be much different to the ones from the IC, which is explained by different mechanisms of producing current in both detectors. Due to its high sensitivity, the DD is useful for the measurement of fast protons. Both detectors can be used for simultaneous measurement of soft X-rays and ions from the same laser shot and the data obtained are complementary.View full textDownload full textKeywordsdiamond detector, laser plasma, X-ray emission, ion emissionRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/10420151003718808
