In this chapter, issues of applying the radio frequency quadrupole (RFQ) accelerator to ion implantation for material modification and microelectronics will be discussed at first. Subsequently, several examples of the RFQ-based implanters will be introduced, with an emphasis on the ladder IH-RFQ accelerator at Peking University, of which the output beam(More)
Ground subsidence in West Tianjin area is explored by means of the persistent scatterer (PS) networking interferometric synthetic aperture radar (PSNInSAR) technique. The pivotal algorithm of the PSNInSAR is briefly represented and the computation is based on 15 high spatiotemporal resolution (HSTR) TerraSAR-X (TX) SAR images acquired between Mar., 2009 and(More)
