====== Using the Physics Calculator ======

==== Calculating Power ====

  - Direct yourself to either the [[pages:phy_calc|Physics Calculator]] or [[pages:mps_op|MPS Operator]] page, located on the FRIB Launch Page.
  - If on the **Physics Calc** page, look at the bottom left of the page for //Atten. Power Calc//. On **MPS Operator** you will find this in the upper right, under the //Beam Power// and //Super Convenient Controls// panels.
  - If you want to predict __Power__ using __Current__, use //Attenuation Power Calc//. If you want to predict __Current__ using your desired __Power__, click //Atten. Current Calc// directly to the right of //Atten. Power Calc//.
  - Regardless of the menu selection in Step 3, you will be asked for the following parameters that can be found in the following locations:
      - __Ion Mass (amu)__ - HourLog or Display 1
      - __Pre-strip Charge__ - HourLog or Display 1
      - __Final Energy__ - FRIB Launcher -> Diag Launcher -> BPM Overview -> Fixed BPM Overview. Column //Energy Estimate//, Row //LS3 Exit//.
      - __Stripping Efficiency (%)__ - Display 1 if available, but Diag and AP have different methods
  - Depending on your menu selection for Step 3, you'll have to find one of the following, which can be found in the following location:
      - __1102 Current uA__ - FRIB Launcher -> Diag Operator. Look down into //Faraday Cups// and find //1102//. **Note:** If you're on __MPS Operator__ there will be an automatic readback that gets the value from //1102// and displays a constantly updating power estimation.
      - __Power__ - Consult limits or desired power from other sources
  - From there, ensure all values are properly entered, then consult the calculated bottom value,
