Research abstract
A UNIQUE INSTRUMENT NOW EXISTS THAT CAN BE USED TO FABRICATEMONOLITHIC, HIGH-GAIN MICROCHANNEL PLATES (MCPS) THROUGH THE "SHEARING" APPROACH. IT WILL ACCOMMODATE MCP BLANKS RANGING IN SIZE FROM 20MM TO 85MM DIAMETER. BY DESIGN, IT WILL PRODUCE BOTH "C" AND "J" TYPE PROFILE GEOMETRIES. PRESENT RESEARCH INDICATES THAT A CUSTOM BLANK IS REQUIRED WITH A MATRIX WALL THICKNESS SUBSTANTIALLY LARGER THAN THOSE NORMALLY MADE. THIS WILL REQUIRE THE FABRICATION OF ASTARTING BOULE, WITH AN INNOVATIVE BLEND OF GLASSES AND GEOMETRY. THE OBJECTIVE OF THIS PROJECT IS TO PROCURE CUSTOM 25MM-FORMAT MCP BOULE MATERIAL FROM A COMMERCIAL MANUFACTURER, SHEAR THE BLANKS AND FABRICATE HIGH-GAIN, 15MUM RESOLUTION DEVICES. FINAL GAIN IS DETERMINED BY PLATELENGTH-TO-DIAMETER (CHANNEL THICKNESS TO PORE DIAMETER) RATIO. RATIOS OF 100:1 AND 120:^ WILL BE TRIED, IN AN EFFORT TO PROVIDE PLATES DEMONSTRATING USABLE GAINS IN EXCESS OF 5 X 10(5), AT BIAS VOLTAGES BELOW 2500 VDC AND STRIP CURRENTS BELOW 20 MUA.
