PREAMPLIFIER FOR CHARGED PARTICLE DETECTION |
摘要 |
A preamplifier is provided for correction of overshoot or undershoot effects present in a signal received from a charged particle detection electrode. The preamplifier is ground-isolated from the charged particle detection electrode and comprises: a main amplification stage, configured to receive and amplify the isolated signal; a feed-forward stage, configured to generate a compensation signal from the amplified ground-isolated signal, the compensation signal being generated to mirror the overshoot or undershoot effects; and an output, arranged to provide an output signal that is a combination of the amplified ground-isolated signal and the compensation signal. A charged particle detection arrangement comprising the preamplifier is also provided. |
