WIDE DYNAMIC RANGE MICROCHANNEL PLATES F6584 SERIES 20 µA Output Current is Available * The F6584 series is a wide dynamic range MCP that offers more than ten - fold increase in maximum output current compared to conventional MCPs. This increased current capability is due to low plate resistance. When operated in pulse counting mode, the F6584 series MCPs also provide maximum counting capability that is more than ten - fold higher than conventional MCPs. The design is optimized to prevent resistance reduction resulting from high power consumption or high temperature operation. The F6584 series MCPs therefore offer excellent stability and reliability even during high current or high temperature operations. This results in a very wide dynamic range, making these MCPs ideal for various applications such as mass spectrometers and usage for high counting PMTs.

In ad- dition electron bombarding may be effec- tive. TMCPB0041EB TMCPB0042EC TMCPA0030EB
