ELECTRON TUBE PRODUCTS 24 News 2017 Vol. 2 New F13446-11 MCP Assembly F13446-11 Compact MCP assembly capable of floating operation in a range of ±5 kV The F13446-11 is an MCP assembly with fast time response which is capable of time-of-flight (TOF) measurements. It operates with the high voltage electrode (MCP IN) at a voltage ranging from -5 kV to +5 kV, making it possible to select the optimal electric potential for positive ions, negative ions or electrons to be measured. The assembled MCP is robust and reliable, and exhibits low time jitter. Differences from previous models Unlike the previous compact MCP assembly F12395-11, the F13446-11 includes a coupling capacitor that allows setting the high voltage electrode at a voltage ranging from -5 kV to +5 kV.
