    keyword=Some Al background analysis

    Some Al background analysis. These are just preliminary plots...messing around with exploring the Aluminum distributions from both Dummy Al and production target (loop 3) runs: 4460 (prod targ) and 4469 (dummy Al). All comments are welcome...It looks like if we put together many runs with full statistics analyzed, we could pullout a loop 3 window background rate assessment...in case we cannot get the empty loop 3 measurement. Either way, we could use an analysis of this data to help us better understand the Al background contamination.
