A silver halide emulsion is disclosed, comprising silver halide grains having a chloride content of not less than 90 mol % and internally doped with an iridium compound and a compound forming a stronger electron trap than said iridium compound, the silver halide grains meeting the following requirement:. According to some embodiments of the present invention, one or more erase pulse parameters may be associated with each of a number of array segments within an NVM array. The second end comprises a compressible reservoir containing a fluid, wherein, when the second end is compressed, the fluid is transmitted from the reservoir toward the first end through passageways to wet the luer proximal end.
