Dear Harry

I am not quite sure though whether I understood everything correctly: after you reached the nominal voltages the current was low (~ 5 nA) except for three excursions which reached the trip limit, is this correct?


Thats correct

I think the 'eruption' may well be due to a burning piece of dust. It lasted for an hour or so, right?


Yes it lasted for ~75 min.

I will organize an extra forum for chamber tests. I think it is very useful if people from time to time submit some of their results there.


Very good- thank you.


Regards

Sascha
