Development of a dose evaluation method for cell irradiation using glass capillaries with end-windows

Microbeams of MeV ions focused through tapered glass capillaries with end-windows have been used for the irradiation of small volume (order of 1μm) inside living cells cultivated in liquid medium. In order to control the dose with accuracy of about 1 MeV, single ion irradiation and its counting method are required. We propose here the possibility of single ion counting by using glass capillaries with plastic scintillator end-windows.
