N1 - Funding Information:
It is a pleasure to thank Prof. A. Noda, Dr. H. Souda and Mr. H. Tongu at Kyoto University and Prof. T. Shirai at the National Institute of Radiological Sciences. They strongly supported us in the electron beam test. We would like to thank Prof. S. Kopp, Mr. M. Proga and Dr. L. Loiacono at the University of Texas at Austin, Dr. R. Zwaska and the staff of Fermilab for the test at the NuMI beamline and for valuable information about an ionization chamber. We also have had the support and encouragement of the members of the KEK neutrino group. They have worked together with us for the muon monitor and for the T2K experiment. This work was supported by MEXT and JSPS with Grant-in-Aid for Scientific Research on Priority Areas 18071007, Young Scientists S 20674004, JSPS Fellows, the Global COE Program “The Next Generation of Physics, Spun from Universality and Emergence” and the Japan/U.S. Cooperation Program in the field of High Energy Physics.

N2 - This article describes the design and performance of the muon monitor for the T2K (Tokai-to-Kamioka) long baseline neutrino oscillation experiment. The muon monitor consists of two types of detector arrays: ionization chambers and silicon PIN photodiodes. It measures the intensity and profile of muons produced, along with neutrinos, in the decay of pions. The measurement is sensitive to the intensity and direction of the neutrino beam. The linearity and stability of the detectors were measured in beam tests to be within 2.4% and 1.5%, respectively. Based on the test results, the precision of the beam direction measured by the muon monitor is expected to be 0.25 mrad.
