The 8000-ton water IMB nucleon decay detector has good sensitivity to the neutrino burst associated with the collapse of stars. It is particularly sensitive to the ve charged current interactions with protons but can also record other neutrino interactions through ve scattering. Signal, noise, physics objectives, and detector modifications that would enhance burst detection are discussed. The objectives include astrophysical questions about the pulse structure and power. It also may be possible with a distant source to study neutrino masses and neutrino oscillations. ; © 1984 American Association for the Advancement of Science. 28 January 1983; accepted 24 June 1983. The IMB detector is a collaborative effort of the University of California at Irvine, the University of Michigan, Brookhaven National Laboratory, the California Institute of Technology, Cleveland State University, the University of Hawaii, University College London, and the Tata Institute of Fundamental Research. The members of the collaboration are R. M. Bionta, G. Blewitt, C. B. Bratton, B. G. Cortez, S. Errede, G. W. Foster, W. Gajewski, M. Goldhaber, T. Haines, T. W. Jones, W. R. Kropp, J. Learned, E.
