Filed: 1985-02-22
Abstract: PURPOSE:To remove effect of the enlargement of ion pulse length on a spectrum by instantaneously changing control voltage which is applied to a control electrode after a specified time elapsed from ion generation. CONSTITUTION:When a trigger pulse generating means 10 outputs a trigger pulse 1, a laser power source 11 is operated, and a pulse laser 14 is irradiated to a sample 3 from a laser generator 13, and an ion pulse 15 is generated near a back plate. On the other hand, a trigger pulse 12 is also inputted to a delay means 9, and outputted to a control voltage generating means 8 as a delay pulse 16 after a specified delay time elapsed. The delay time to which is set with the delay means 9 is equal to the time within which generation of the ion pulse 15 is completely finished. The control voltage generating means 8 is operated with the delay pulse 16, and changes the control voltage Vg, which is applied to a control electrode 4, so as to have the same potential as a drift tube 6 in a step shape and draws out ions.
