Brief
The Hexanode, a three-layer delay-line anode for microchannel plate detectors, offers improved multihit detection capabilities, enabling the determination of the arrival time and position of multiple particles in a shower.
Summary
This article discusses the development and advantages of a new type of microchannel plate detector called a Hexanode. This detector is designed to improve the detection of multiple particles arriving at the detector in quick succession (multihit events).
- Traditional microchannel plate detectors with delay-line anodes struggle to differentiate particles arriving close together in time and space.
- The Hexanode utilizes three layers of helical anodes, allowing it to distinguish and locate particles even when they arrive simultaneously, as long as their spatial separation is greater than the electronic dead time.
- This new design rivals the multihit capabilities of pixel-based anodes but with less complex electronics and superior position resolution.
