The MINOS experiment: 2012 results

Proceedings of Science 2012-July (2013)

Abstract:

Data taking has now finished for the low-energy phase of the MINOS experiment. The main osillation results from these data are presented. The disappearance of muon neutrinos and muon anti-neutrinos from the NuMI beam are combined with atmospheric data to produce a best fit for the atmospheric oscillation parameters. The |?m232| measurement, which is the most constraining in the world, is (2.39+-000910) × 10-3eV2. The value of sin2(2?32) is measured to be 0.957+-00035036. The latest results of the electron neutrino appearance search are presented and rule out ?13 = 0 at 2s. Results from the MINOS time of flight study are also presented and a preview of the physics available in the next phase of the experiment, MINOS+ is given.

Abstract:

Precise measurement of neutrino beam direction and intensity was achieved based on a new concept with modularized neutrino detectors. INGRID (Interactive Neutrino GRID) is an on-axis near detector for the T2K long baseline neutrino oscillation experiment. INGRID consists of 16 identical modules arranged in horizontal and vertical arrays around the beam center. The module has a sandwich structure of iron target plates and scintillator trackers. INGRID directly monitors the muon neutrino beam profile center and intensity using the number of observed neutrino events in each module. The neutrino beam direction is measured with accuracy better than 0.4 mrad from the measured profile center. The normalized event rate is measured with 4% precision. © 2012 Elsevier B.V.

Synchronization between remote sites for the MINOS experiment

Abstract:

In the context of time-of-flight measurements, the timing at the departure and arrival locations is obviously critical to the outcome of the experiment. In the case of neutrino time-of-flight experiments, the locations are many hundreds of kilometers apart with synchronization requirements of nanoseconds for several months at a time. In addition to the already stringent set of requirements outlined above, the locations of the origin of the particle beam and the detector need to be precisely determined. NIST and USNO have provided the MINOS (Main Injector Neutrino Oscillation Search) collaboration with both hardware and expertise to synchronize the two sites of the experiment, the accelerator at Fermilab in Batavia, IL and the Soudan Mine in northern Minnesota. Two GPS receivers are installed at each location where the local clocks are commercial Cesium clocks. Two more GPS receivers are constantly traveling between locations (including NIST in Boulder, CO) to provide multiple differential calibrations of the fixed receivers. The availability of the TWTFST equipment from USNO allowed for one comparison between the GPS and TWSTFT for the link between the locations, providing an independent means of determining the accuracy of the synchronization. Several months of continuous GPS data are now available, including the two-way calibration instance and several differential GPS calibrations. The results of data processing yielded synchronization stability below one nanosecond with accuracy at the nanosecond level over several months. © (2012) by the Institute of Navigation.
