Main components

README.mdPhotomultiplier tube resistor divider
A photomultiplier tube (PMT) resistor divider is a crucial component in the operation of photomultiplier tubes. These devices are highly sensitive light detectors used in various applications such as medical imaging, nuclear and particle physics, and scientific research.
The resistor divider network within a PMT is designed to ensure proper voltage distribution across the dynodes of the tube. Dynodes are the intermediate electrodes that amplify the signal produced by incident photons. The correct biasing of these dynodes is essential for optimal performance, signal amplification, and minimizing noise.
The typical resistor divider configuration involves a series of resistors connected between the high-voltage supply and ground. Each dynode is connected to a tap between two resistors, thereby establishing the necessary potential differences.

Questions
How big is the Pmt divider PCB?
It measures 25 × 4.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pmt divider use?
15 parts, built around the CC0805KKX7RBBB103. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Pmt divider KiCad files?
From the dani9875/pmt_divider repository on GitHub, at the commit this page was made from: the board is pmt_divider.kicad_pcb and its schematic pmt_divider.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pmt divider design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
