Research Abstract |
To investigate the production mechanism of clustered DNA damage, I developed the time-of-flight ion mass spectrometer. If the two ions were produced by a single photon, the coincidence signal can be detected on the ion mass spectrum. Moreover, I measured the clustered DNA lesions induced by monochromatic soft X-rays by an enzymatic method.
