The Run faraday cup vs I0L02 is in [[http://hallaweb.jlab.org/experiment/E08-011/documents/bcm/bcmLogs/BcmLog_125 BcmLog125]]

Faraday vs Injector current - From BCMLOg-125 - 20Feb07


'''Faraday_Current = (0.28+-0.03) + (0.994+-0.001) * IBC0L02_Current '''

'''Faraday / Injector = 1.0027 +- 0.0006 , for Current >5uA '''
