 S.P.A.R.T.A.N force, still trapped in the town of Lakeview, has been sent as part of a larger governmental team to work on developing a micro-particle accelerator on the outskirts of town. Why does a town the size of Lakeview need a micro-particle accelerator? You are not at liberty to say. Your team is tasked with modeling the initial part of the accelerator, which uses a constant electric field to accelerate the charges. The concept is that the particles will enter a tube that is encapsulated by rings of charge. Your team needs to demonstrate that this concept will produce a __constant__ electric field. S.P.A.R.T.A.N force, still trapped in the town of Lakeview, has been sent as part of a larger governmental team to work on developing a micro-particle accelerator on the outskirts of town.

 +===Learning Goals===
 +  * Review ideas of electric field, superposition, separation vectors, and distributions of charge 
 +  * Review ideas of interpreting code: while and for loops, lists, creating objects/shapes
 +  * Explain how you created a constant electric field using rings of charge
 +  * Explain what would happen to a charge if it were placed in the electric field
 +</WRAP>
  
 +Conceptual Questions:
 +  - (Part 1) What does it mean for a vector (like Electric Field) to be "constant"?
 +  - (Part 1) What would you expect the electric field to look like for an observation point at the center of the ring? What about a ring of observation points aligned with the ring (z=0) but with a radius inside the ring of charge? What about a ring of observation points with some z value away from the ring of charge? Draw these out on the whiteboard.
 +  - (Part 1) Comment your code line-by-line and make sure everyone understands what each line is doing.
 +  - (Part 2) When you have multiple rings of charge, how do you get a constant electric field?
 +  - (Part 2) What is a surface charge gradient?
 +  - (Part 2) Why does this set up count as an "accelerator"? What would you need to change to make the accelerator stronger?
