MOSTAB（Monochromator Stabilization）is the is the system that control feedback by measures the postion and light sprectrum. Feedback controls the angle of the first crystal of the dual crystal spectrometer so that they are constant.
Flex MOSTAB is developed the conventional DSP type MOSTAB with NI Single-Board RIO (NI sbRIO-9636), which is an NI general-purpose board equipped with CPU and FPGA that can be controlled by NI LabVIEW, and peripheral circuits 19 inch rack mount system inside the chassis. By developing DSP to FPGA, we have new functions that have never been available.
Feedback controller of Flex MOSTAB consisted of FPGA and Real-Time OS, even computer has been stopped working, system is still able to work
Able to support more object type
The feedback controller has long life span and able to do parts replacement by employing NI RIO.
Coding reuse and expansion
Control part use NI LabVIEW which is able to run regardless hardware, and also able to freely adjust coding logic.
Parameter Feedback adjustable
Feedback parameter is adjustable and easy to learning.
