Beam current = 1 µA.



"Baseline"

 Ax = -0.6   Ay = -1.4

 Bx = -0.7   By = -1.0

Channel Currents (µA)

 0= -8.3

 1= -1.7

 2= -25.4

 3= -2.5

 4= -23.8

 5= -23.8

 6= -9.4

 7= -4.2



X scan.. (Ay=-1.6, By=-1.0)

 No appreciable change in currents all the way out to +4mm in A and B.

 BB HV trip (and EP chamber trip) at Ax=-1.5, Bx=-1.75



Y scan (Ax=-0.6, Bx=-0.6)

 BB HV trip (and EP chamber trip) at Ay=-3.3, By=-3

 At Ay=3.0, By=3.44

   Chamber Currents:

   0= -13.0

   1= -2.7

   2= -35.9

   3= -3.7
