Phase and Synchronous Detector Theory as Applied to Beam Position and Intensity Measurements
نویسنده
چکیده
A popular signal processing technique for beam position measurements uses the principle of amplitude-modulation -tophase-modulation (AM/PM) conversion and phase detection. This technique processes position-sensitive beam-imagecurrent probe-signals into output signals that are proportional to the beam's position. These same probe signals may be summed and processed in a different fashion to provide output signals that are proportional to the peak beam current. This paper derives the transfer functions for the AM/PM beam position and peak beam current processors.

Vibration suppression analysis for laminated composite beams embedded actuating magnetostrictive layers
This paper presents the analysis of vibration control of a laminated composite beam that including magnetostrictive layers. The formulation of problem is presented based on the shear deformation beam theory. For vibration suppression, the velocity feedback control with constant gain distributed is considered. Navier's method is applied to analyze the solution of vibration suppression of laminat...
متن کاملGeneralized in-line digital holographic technique based on intensity measurements at two different planes.
In-line digital holography based on two-intensity measurements [Zhang Opt. Lett. 29, 1787 (2004)], is modified by introducing a pi shifting in the reference phase. Such an improvement avoids the assumption that the object beam must be much weaker than the reference beam in strength and results in a simplified experimental implementation. Computer simulations and optical experiments are carried ...
متن کاملSimulation of an Airy Beam with Optical Vortex under Fractional Fourier Transforms
First, this study obtained the fields of an Airy beam (AiB) with optical vortex (OV) for a Fourier transform (FT) system and a fractional Fourier transform (fractional FT) system; thereafter, their intensity and phase patterns were simulated numerically. The splitting on each line of the phase pattern indicates the position of an OV. The results show that the OV position will change when the po...
متن کاملPhase Only Synthesis of Antenna Patterns Using Iterative Restoration Methods
In this work, the method of iterative Fourier transform phase reconstruction, conventionally used in holography and optical image reconstruction, is applied to phase only synthesis of antenna patterns. The method is applied to two types of pattern synthesis problems: "main lobe beam shaping" and "side-lobe-level reduction". The proposed method is most useful in the efficient employment of attai...
متن کاملOn-line Phase Space Measurement with Kicker Excitation
A new method for on-line phase space measurements with kicker excitation at COSY was developed. The position data were measured using the analog output of two beam position monitors (BPMs) and directly monitored on a digital storage oscilloscope with an external clock (bunch-synchronous sampling). Nonlinear behavior of the proton beam was visible as well as were resonance islands. Typical measu...
