Preliminary results from the first discharging indicate the charge has been reduced to 1/4 of the originally
measured charge. As we were dissatisfied by the negative to positive ion ratio and the flow rates in the initial
attempt, we made a second injection on August 8 with 1/2 the flow rate and about 3 times the ion current
into the test mass chamber. The charge on the etmy has not been measured yet. The new flow conditions are closer
to those in the original experiment done at MIT which reduced the charge to 0 +-10% of its initial value.
Again, once all the data is together, a more informative posting of the results will be made.
