| 内容記述 | Compact hard X-ray source using the X-band linear accelerator to which is developed in Nuclear Engineering Research Laboratory the University of Tokyo makes beam size 100micrometer pulse laser and an electronic beam collide, and generates X-rays by Compton scattering. In order to collide a laser electronic beam efficiently, the beam profile monitor that can measure a beam profile with sufficient accuracy is indispensable. As a beam profile monitor which has resolution between the altitude which can measure 100 micro meters, it is focused on Wire scanner, OTR(Optical Transition Radiation) monitor and Screen monitor(alumina ceramics), and the research and development are done. Moreover, since it has the angular distribution decided by the energy of electron beam also besides measuring a beam profile. The angular distribution of optical transition radiation is asking for the electron beam dispersion angle and beam size in the beam waist simultaneously, it can expect measuring beam emittance. The measurement comparison with the QUAD scan method shows the emittance measurement possibility. If this measurement method is success the emittance measurement is done only 1 shot measurement. Supposing the X-band linear accelerator, some verification experiments are performed with S-band linear accelerator (E=20MeV) in this institution. From last experiment, we have observed the blots of Screen monitor about 75 micro meters. From the thickness of the screen was 100 micro meters, we can determine the blots of the screen monitor are depend on the thickness of screen. So the screen monitor cannot measure the beam size less than 100 micro meters. Measuring the beam profile using these three (OTR, Wire Scanner, Screen monitor) beam profile monitors repeatedly, we have achieved the resolution within statistically 10 micrometers. From the experiment of the OTR angular distribution measurement, we have achieved to measure the electron beam energy within the resolution 1MeV and the beam emittance was measured about 20 [pi mm mrad], this result shows the agreement with the result from QUAD scan method. In this poster presentation, we report the result of the verification experiments. | |||||
