Status of Stanford magnetic monopole search with eight-loop superconducting detector

A model has been developed which includes all significant inductive coupling of the Stanford monopole detector pickup loops and allows variation of the individual inductances to optimize the fit to the data. With this model, one can calculate the response of the detector to monopoles, with allowances for the inoperative panels and discrepancies in the inductances. The detector has been in operation for approximately 450 days at this time. Of this, there are 6600 hours of computer data, and 6000 of these hours meet the criteria for active sensing time. No candidate monopole events have been observed. The exposure to date represents a limit on the flux of cosmic ray magnetic poles of 7.8×10^-13 cm^-2 s^-1 sr ^-1 at 90% confidence level
