40mm MCP Dual Detector on 6 Inch Conflat Flange

DUAL (CHEVRON) MCP MICROCHANNEL PLATE DETECTORS

Designed to handle the fast ion pulses provided by our linear and reflectron Time Of Flight Mass Spectrometers. Our MCP Microchannel Plate Detectors have a 50 ohm coaxial output and provide high gain (10e6 to 10e7) with sub-nanosecond rise time. They are fitted with SHV coaxial UHV feedthrus that can be operated from external power supplies or voltage dividers. All of our MCP Microchannel Plate Detectors are fitted with a 90% transparency input grid. This presents a flat, field free plane to the incoming ions. The input grid has its own SHV feedthru and can be operated at any potential. A shorting cap is provided for operation at ground potential. Our divider circuits are close coupled to the detector by way of short SHV cables which results in low noise, clean signal with no ringing.

 

Our MCP Microchannel Plate Detectors are UHV ultra high vacuum compatible and can be baked to 300 degrees C. In the dual (chevron) configuration two microchannel plates are used. Replacement microchannel plates for our detectors are available from at least three different vendors.

All dual detectors can be used to detect either positive ions, negative ions or electrons by simply using different input voltages/divider circuits.

 
         

Z-GAP HIGH SENSITIVITY MCP MICROCHANNEL PLATE DETECTORS

A special three plate MCP Microchannel Plate Detector is also available for detecting small signals. The addition of the third MCP and suppression grid offers much higher gain, better signal/noise ratio, and a higher input/acceleration voltage for incoming ions.

Also fitted with an input grid, the Z-Gap MCP Microchannel Plate Detector provides incoming ions with a post acceleration voltage of nearly -5KV.

Z-Gap MCP Microchannel Plate Detectors are available with 18mm, 25mm or 40mm Microchannel Plates.

Note: Z-Gap detectors cannot be used to detect negative ions or electrons.
