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. FEATURES ● Wide Dynamic Range Typ. 20 µA Maximum Output Current * ● Operable in high temperature condition (+350°C Max. c) ● High Gain and Low Noise * When the MCP resistance is less than 10 MΩ.

TMCPA0030EB PRECAUTIONS FOR USE ● Avoid touching the MCP or MCP assembly with bare hands. ● Handle the MCP only in a clean room since dust and humidity may adversely affect MCP characteristics. ● The MCP should be operated in vacuum below 1.33 x 10 -4 Pa(1 × 10 -6 torr). ● The MCP should be kept in vacuum or dry nitrogen gas atmosphere during long periods of storage. ● When outgassing from the MCP occurs, baking the MCP at 400°C maximum in a vacuum system is recommended. In addition electron bombarding may be effective.
