Beam - Overview¶
MicroBooNE detector is exposed to neutrinos from two neutrino beamlines; Booster Neutrino Beamline (BNB), and Neutrinos at Main Injector (NuMI). The primary source of neutrinos for MicroBooNE is the BNB, while NuMI primarily serves NOvA, Minerva, and MINOS+ experiments. The main goal of beam monitoring is to check that BNB is on and that we are getting physics quality data. The NuMI beamline is being monitored by other experiments, and it is not necessary for MicroBooNE shifter to monitor it. Nevertheless, it is useful to know if it is on or off as shifter needs to make sure the detector is triggering on NuMI events if the NuMI beam is on.
Below is a list of things to pay attention to when monitoring beam. More detailed explanation of what is being monitored can be found in Beam - Guide
1) Is BNB on? Is NuMI on?
- find out by looking at Accelerator Complex Current Beam Conditions: http://www-bd.fnal.gov/notifyservlet/www
- check the comments at the bottom of page
- if BNB rate is greater than 0, then beam is being delivered
- the MCR e-log for the Booster Neutrino Beamline can be accessed using: https://www-bd.fnal.gov/Elog/?logNames=External+Beamlines&categoryNames=BNB
- the MCR e-log for the NuMI beamline can be accessed using: https://www-bd.fnal.gov/Elog/?logNames=External+Beamlines&categoryNames=NuMI
2) If BNB is on, check BNB monitoring page: http://www-bd.fnal.gov/synoptic/display/BNB/BNBStatus
- is beam intensity, position along the beamline stable?
- are there any alarms (anything red)?
3) IF BNB is on, check the IFBeam monitoring page to make sure we are storing the data from beam instrumentation. The page should be updating and showing recent data.
If IFBeam monitoring page is not updating and it should (there is beam), contact operations support 1-844-343-2326.
