CAMINO CODE FACT SHEET

1. Code Name: CAMINO

2. Category: VIIa. Linear Stability: 2D Ideal

3. Responsible Physicist: M. Chance

4. Others involved in code development:

5. One line description: Constructs s-a stability diagrams for every tokamak flux surface.

6. Computer systems which code runs on: Cray

7. Typical running time (if applicable): 15 minutes/case

8. Approximate number of code lines: 4500

9. Does this code read data files from another code? Reads MAPDSK, MPOUT1 from MHD mapping codes.

10. Does this code produce data files that can be read by another code? If so, explain. Data is read by a code which constructs 2D and 3D stability boundaries in (s, a, y).

11. 1-2 paragraph description of code: CAMINO constructs the s-a stability curves generalized to arbitrary 2-D tokamak equilibria. The curves from all the flux surfaces generate a 3D stability ballooning boundary in (s, a, y). This can be used to tailor the plasma profiles to achieve the 2nd region of stability or optimize the b for the 1st region.
