Introduction
Spin Flip System is designed for controlling Hall A Polarized He3 Target automatically flip spin direction during experiment run time. The physics goal is to reduce systematic false asymmetry, driven by experiment Transversity and d2n.
Core functions for this system are
- Control the target spin flip consequence
- Acquire and Record target spin state
- Output target spin related information into DAQ system, therefore data stream
- Interaction with human (Target Operator)
- Communicate with related target software/hardware
For quick learning this system, please read Shift Worker Quick Start.
