We have constructed an eddy current shielded room from high‐conductivity aluminum sheets, 1.88 cm thick. A series of measurements designed to test the performance of the room has been carried out. The results of the measurements have been compared with theoretical predictions and also with the results from similar rooms reported in the literature. In some respects the agreement is good while in other respects considerable discrepancy exists. The response time of the room to a uniform field was found to be in good agreement with theory, whereas the response to a nonuniform field was found to be much worse. We also found that the room does not shield the vertical field component as well as the horizontal components. We give the reason for this and suggest a possible solution.
