Nosecones


Prior to the 200x shutdown, the nosecones started at z=±40.1 cm (see this email from 2002). In the summer of 200x, the nosecones were removed, and 1 cm was machined off.  
   
Normal setting, in phnx.par nconeflg=1. The brass goes from z = 41 cm to z = 60 cm.


If you set nconeflg to a value between 41.0 and 60.0, the brass gets trimmed at that value of z, and the space gets filled with borated polyethylene. This is for studies of neutron backsplash from the nosecone and magnet iron.




Material definition: in February 2015, Mickey noted that in Pisa, the material was defined as copper. The actual material is brass, ...
