I still have qualms about the input to the ADCs.   It is very 
peculiar.   To see that look at the circuit and ask how current can get 
from the collector of the PM to the dynodes.   It ends up by going 
through all the grounds.  Fortunately the ADVs ar excellent and only the 
current across RL is amplified and integrated/

I cannot see a problem this will ead to.  But please bera it in mind if 
anythg goes wrong.

I will not be available till after MAy 1  then I go away may 14 to 30 or 
so and if we continue to June i will take shfts then

Dick Wilson
