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

Exception Handling
Status Page
Status Page Contain two list of status reports of target control software. They are User Report and Automatic Report.
- User Report are generated by pressing "generate report" button on target Main Control GUI.
- Automatic Report are automatically generated after every spin flip or once an error occured.
