Hey Dr Aso, I didn't explain my dilemma very well. I have a sphere of quartz to generate Cerenkov photons. Attached to one hemisphere of that sphere are quartz columns to catch and direct the photons(I have attached a picture of geometry).

 At the end of each column I would like to have a detector and scorer to tell me which column the photons went down. Right now I have made all of the columns using do loops and one array 100+ columns. 

Since all the columns are in one array, I tried to instantiate and point all of my scorers in an array of scorers as well.

With array of columns, do I need one G4MultiFunctionalDetector or an array of G4MultiFunctionalDetector, one element for each column?

For my scorers, I have made thin columns at the ends of each quartz column. I have made an array of G4PSPassageCellCurrent.

I read in your powerpoint that you recommend using primitive scorers if I do not have too many scorers. By making an array of scorers with 100+ elements, do I have too many scorers.

I looked at HandsOn3, but they are using replicas to create their bins. I have tried, but have not been successful in converting their approach to my array geometry.

I am not sure if I am even approaching the problem correctly, any guidance would be greatly appreciated.

Thank you for your time, Matt Worden
