ST Quartz Acoustic Wave Sensors with Sectional Guiding Layers
We report the effect of removing a section of guiding layer from the propagation paths of ST-quartz Love wave sensors; this offers the ease of fabrication of a polymer guiding layer whilst retaining the native surface of the quartz which may then be used for the attachment of a sensitizing layer. Data is presented for rigid and viscous loading, which indicates a small reduction in mass sensitivity compared to a Love wave device. Biosensing capabilities of these discontinuous ‘sectional’ guiding layer devices are demonstrated using protein adsorption from solution.
The soft X ray streak camera is very important detection tool for studying soft ray time characteristics. We calibrated its relative energy response and gain with synchrotron radiation light source on the BSEF. The experimental results agree with those calculated by B.L. Henke.
