Research Abstract

We proposed several new measurement techniques for composite measurement method. The results of them are as the followings.
(a) Measurement of micro-pulse width of LINAC beam using standing wave measurement: We propose a new technique based on transformation from the time domain into the spatial domain to determine the time pulse width. It requires measurements of only spatial standing wave distributions. These distributions can be detected with only use of the low frequency detector systems (e.g., oscilloscope, A/D converter etc.) The availability of this technique is shown by the numerical demonstration and the result of experiments.
(b) Transverse profile estimation with measurement of electromagnetic fields: To demonstrate the availability of real time measurement system for transverse profile, we made the software system that includes a pseudo signal generator, the Kalman filter and parallel genetic algorithms. This system can simulate time dependent changes of beam profile. The est … More imated result is compared with the given profile. As the result of the time response analysis, we showed this system gave us almost good estimations except rare occurred instability.
c Electron beam measurement by X-ray framing camera: We investigated the spatial resolution of X-ray framing camera for 2-dimensional measurement of LINAC electron beam profile. In generally, the test chart is applied to measure the spatial resolution. However, good test chart is not found for the soft X-ray. Thus, we propose a new technique named virtual test chart algorithm that use only a knife edge. Further we proposd a method of improving the spatial resolution using the magnetic field.
(d) Simultaneity improvement of the ultra-high speed camera: We pointed out a problem about coincidence characteristics of image when ultra-high speed camera operates with sub-nano-second shuttering, and proposed the improvement way considering the shape of electrode. As the result of numerical analysis, the disperse in time is reduced from 30 pico-seconds to 5 pico-seconds. Less
