Pulse oximetry represents a ubiquitous clinical application of optics in modern medicine. Recent studies have raised concerns regarding the potential impact confounders, such as variable skin pigmentation and perfusion, on blood oxygen saturation measurement accuracy pulse oximeters. Tissue-mimicking phantom testing offers low-cost, well-controlled solution for characterizing device performance studying error sources, which may thus reduce need costly vivo trials. The purpose this study was...
The paper describes measurement and analysis of beam instability made at SOLEIL in comparison with the expectation using numerically estimated impedance budget. A multibunch is found to be under a strong influence resistive-wall fast beam-ion instabilities, way that largely depends on local position bunch train. For single bunch, measured reactive turns out larger by nearly factor two than calculated all three planes. roughness due NEG coating assessed as possible cause.
Abstract The L inear I nternational Fusion Materials Irradiation Facility P rototype Ac celerator (LIPAc) is under commissioning in Rokkasho Institute Japan and aims to accelerate 125 mA D+ at 9 MeV Continuous Wave mode for validating the IFMIF accelerator design. To ensure a fine characterization tuning of machine many beam diagnostics are installed spanning from injector dump. operations 1.0 ms pulsed 5 were successfully completed with low power dump 2019. Despite challenges posed by...
