I'm Seiji Yamamoto from Nagoya University.I will introduce our paper recently published for a journal of applied clinical medical physics.The title of the paper is Increase in the intensity of an optical signal with flow saying you are in proton and carbon ion irradiation.This is a collaborating work with Hyogo Ion Beam Medical Center.Background.We recently discovered a luminescence water at lower energy than tranquilized threshold.With a proton of 100MVB, this is lower than the tranquilized threshold.Proton is irradiate to water phantom and CCD camera image luminescence.We can successfully image a clear distribution of luminescence by using CCD camera.The linearity of this luminescence is excellent.And also the intensity was exactly the same as the dose after correction of the tranquilized from the gamma photons.Also there is no quenching for protons.Problem in imaging of luminescence water is because the light production of luminescence was small.0.5 photons per MAV so relatively long time is needed for imaging.For this image of luminescence water of proton several minutes were needed for scanning proton traffic system.Proton is a promising material to increase the lighting intensity of luminescencebecause processing converts UV and blue light to longer wavelength of light.This is a photo of fluorescent water during irradiation of UV light.Proton converts the UV light to the longer wavelength of light.Length was 515nm average.Optical imaging of fluorescent water by irradiating proton and carbon ion were conducted.From the proton carbon ion traffic system being irradiate to fluorescent waterand image the luminescence of fluorescent water using a cooled CCD camera.For a 100 MAV proton this is the image of luminescence water and this is the image of fluorescent water.More than 10 times the intensity was obtained for fluorescent water.For summary with fluorescent the light intensity of luminescence water increased more than 10 times.Much more than we expected.Proton is a possible material to increase the light from luminescence water lower energy than tranquilized threshold.Luminescence water is an interesting finding.If you have any question or comments please send me an email to this address.Thank you for your attention.
