The purpose of this note is to report results of tests on a simple and effective low-pressure burst diaphragm. Rupture of the diaphragm is achieved when on deflection it makes electrical contact with a puncture needle between which 110 volts ac are maintained in series with a 4-amp fuse. Also a convenient method of sealing thin foil diaphragms of both copper and aluminum to all metal vacuum systems was found in developing the burst diaphragm.
