We present results of measurements of spot size and angular divergence of a 30 GeV electron beam though use of optical transition radiation (OTR). The OTR near field pattern and far field distribution are measured as a function of beam spot size and divergence at wavelengths of 441, 532, and 800 nm, for both the single and double foil configurations. Electron beam spot sizes of 50μm rms have be...
This study presents the free vibration analysis of a double tapered beam having linearly varying both thickness and width, by using finite element component mode synthesis methods. To determine natural frequency shape cracked beam, stiffness mass matrices have been obtained. The crack in is modeled as massless spring, divided into two subcomponents from section. spring has derived linear elasti...
In this paper, we present a high accuracy laser range finder and velocimeter using ultra-fast time-to-digital converter (TDC). The system operation is based on the measuring the round-trip time of a narrow laser pulse. A low-dark current high-speed PIN photodiode is used to detect the triggered laser beam and to produce start signal. The pulsed laser diode generates 45W optical power at 30ns du...
