About the AFE single channel PCB

AFE single channel is an open source PCB design by RobertGawron, published on GitHub under the MIT license. It is a 4-layer board measuring 10.5 × 27.4 mm, with 24 components from 13 distinct parts.

Other key parts include the LTC6268xS6-10 and AD8139. By type, the board carries 17 capacitors, 5 resistors and 2 ICs.

It belongs with the sensors designs in this gallery.

From the project

Device for quantitative analyze energy spectra of gamma-ray sources. Allows to study what radioactive isotopes in what quantities are present in measured sample.

The hardware consists of four main parts:

Handles low-level currents produced by the sensor (typically 1uA - 1mA pulses, 10mV - 1V after amplification):

LYSO Scintillator Crystal - Converts gamma rays into visible light pulses through scintillation. The project uses eight crystals, each 22mm x 4mm x 4mm, stacked together into a single crystal assembly with a size of 22mm x 8mm x 16mm. Silicon Photomultiplier: MICROFC-60035-SMT-TR1 SiPM - Converts light pulses from the scintillator crystal into electrical current pulses. The project uses four SiPMs in two channels; each channel contains two…
