[Clas12_high_luminosity] Simulation Update

[Whitney R. Armstrong]

Hi Mac,

If you are referring to the follow-up slides, yes. As you can see from the wiki 
page where I am **now using the same beamline shielding** as Mauri,  
(https://clasweb.jlab.org/wiki/index.php/CLAS12_Drift_Chamber_Occupancy_Simulations) 
the rate at low wire number is reduced. 

Even though we now have the exact same beamline shielding there are still 
considerable differences when comparing the two simulations.  The reason for 
these differences I do not yet understand.

Cheers,
Whit
