Design of single-photon pulse generator based on FPGA
Many performance parameters of photomultiplier tube(PMT)are tested on the basis of the single photoelectron spectroscopy
so single-photon source is essential to the batch test of PMT and requirements of light source for precise single photo electron spectrum measurement.
Purpose:
2
The study aims to design a single-photon pulse generator used in batch test for PMT.
Methods:
2
A control panel for the adjustable pulse signal generator with multi-channel output is designed and implemented after the performance test analysis of PMT.A MAX10-10M08SAE144C8G FPGA(Field-Programmable Gate Array)chip
a STM32F107 ARM(Acorn RISC Machine)controller and a DP83848 Ethernet chip are integrated to realize desired functionalities.PC sends commands to STM32F107
via
Ethernet;then ARM controller analyzes commands and sends them to FPGA to achieve adjustable duty cycle
and adjustable frequency
adjustable amplitude pulse output through the level conversion chip.
Results:
2
Compared with the most often used RIGOO-DG5352 signal generator
the newly-designed single-photon pulse generator showed better performance on both the fall time and the rise time.
Conclusion:
2
The output signals of this single-photon pulse generator could match the requirements in the PMT single photo-electron spectrum test.Also it can be extended to multi-channel outputs for PMT batch test.
