Hardware connections were checked and verified several times. Necessary corrections are being modified in software. Do test runs after all the corrections (with beam and without beam). Analyze data and verify everything is working. Need 2-3 hours test with beam to achieve desired tune parameters to get pure position and angle at target. (assuming beam modulation hardware, software, BPMs are in working condition) Extract detector sensitivities. 18 OPTIM SimulationHardware IssuesDiagnostics Analysis Future Plans

We may be asked to upgrade the IOC in that crate. (All the hardware are installed for modulation)  Need to pull some cables from the BSY service building to our parity DAQ in the Q p weak cage (All the cables are pulled and connections are checked several times)  GUI need to be tested (Its working fine)  LEM rack under construction in Accelerator Division.
