along the path of the electron beam. A small, positive potential is normally applied to the repeller and causes the ions to drift toward the exit slit and into the ion gun and the analyzer. A typical source is shown in Fig. 1. Under ordinary operating conditions, the pressure in the ion source is o

Barry Laffoy,Saraansh Dave,Mahesh Sooriyabandaraveral years photoionization techniques have been applied to this area of research. The experimental techniques of photoionization are generally more difficult to apply than those of electron impact, but have certain strong advantages in the ability to provide more precisely characterized preparation
