December 2013 Experimenters' Meeting Summary and Operations Update

This document outlines the summary of operations from November 25 to December 2, 2013, detailing the performance and intensity metrics of various beam operations including NuMI, BNB, NMuon, and MTest. During this period, NuMI delivered 4.84E18 protons, while BNB and NMuon provided 5.63E18 and 1.99E15 protons respectively. The report also highlights various technical issues, such as a vacuum instability and ongoing maintenance work, along with plans for continued improvements and system upgrades.
