I foud missing  , power  at beam tube ionizer .
was a diode open  , now ion pump current is high .
last calibration was made 20 tears ago , maybe this one was not 
operating for long time , due to a fault .
Now I will try to apply 3500 volt as the manual .
And I hope current go low .

I someone had made this procedure may explain me how to do .
regards i5uxj
