Advanced Shutter Control for a Molecular Beam Epitaxy Reactor

Report No. ARL-TR-8259
Authors: Ryan Enck; Eric Rong
Date/Pages: April 2018; 76 pages
Abstract: An open-source hardware and software-based shutter controller solution was developed that communicates over Ethernet with our original equipment manufacturer (OEM) molecular beam epitaxy (MBE) reactor control software. An Arduino Mega microcontroller is the used for the brain of the shutter controller, while a custom-designed circuit board distributes 24-V power to each of the 16 shutter solenoids available on the MBE. Using Ethernet communications supported by the OEM software, the new shutter controller eliminates the need for proprietary interface cards inside the control computer.
