Description

In prior art, various ion detectors have been developed and used till date.  Some of the most common ones are a Faraday cup and an air ion counter, having a large size, low sensitivity, and a high price; micro-channel plates with a higher energy input, complicated design, and a large size; and individual carbon nanotube based ion sensors having a different and complicated sensor mechanism.  This invention discloses the development and use of a novel, ultrasensitive ion detector made up of various carbon based nanomaterials such as carbon nanotubes and graphenes.

 

Value Proposition

The ultrasensitive ion detector:

•Is associated with a low power input

•Is effectively operable over wide range of substrates

•Enables a higher positional resolution and an ion source imaging as compared to prior art detectors

•Is highly sensitive, having capability to reach a single ion resolution

•Comprises a miniaturized size (nano to micro-scale) with high portability and flexibility as compared to conventional detectors

•Is light weight and highly cost effective as compared to conventional detectors

•Effectively allows for a tunable signal intensity by changing the bias on the device

•Would be commercially useful for the following applications:

o Radioactive leakage monitoring

o Radiation detection in battle field and nuclear power plant

o High energy particle detection for astronaut working at outer space

o Pressure sensor

o Gas leaking monitor

o Electron/ion beam monitor

o Ion detectors

o High resolution ion camera
