Monitoring Beam Power

What Is Beam Power?

Beam Power is a measurement of how much beam we're sending, it's measured in Watts (W) and can be found using the following formula

(Current/Charge) * Mass * Energy * Stripper Efficiency (using latex for this and link following references)

We measure the current from either Farday Cups or BPMs, the charged beam induces current in the cups idk how i guess just attracts all neg to the surface? BPMs no clue

Mass is just dependent on the isotope we're sending

Energy increases as the beam is accelerated by more cavities, so it will change depending on the destination,

Stripper Efficiency is the amount of beam that passes through the Lithium Stripper and Charge Selector in FS1, if the Stripper is turned off then we would have 100% efficiency as all beam would pass through, if it were tuned incorrectly and didn't allow any beam to pass through, then it would be 0%. Another way to think of it is what percent of the initial beam that makes it to the LINAC is the desired charge, if we want a charge state that's 70% of the beam then we'd want 70% efficiency, if we want an additional charge state that's 15% of teh beam then this goes to 85%.
