# Your first run in 5 minutes

This walkthrough takes you from sign-in to a publishable plasma figure.

## 1. Sign in

If you don't have an account, click **Get Started** on the landing page. Trial accounts get 3 days of full Pro access — no credit card.

## 2. Open the Plasma module

Left nav → **Plasma**. You'll see eight standard tabs plus eight Pro tabs (Optimizer, Predictor, Equilibrium, Ballooning, Mercier, Multi-mode, Sensitivity, Convergence, EFIT, Validation).

## 3. Run a Soloviev equilibrium

Click **Equilibrium**. The form is pre-filled with ITER-class inputs:

- R₀ = 6.2 m, a = 2.0 m
- κ = 1.7 (elongation)
- δ = 0.33 (triangularity)
- B₀ = 5.3 T, β_p = 0.5

Click **Solve Soloviev**. In under a second you'll see:

- A 2D poloidal cross-section with flux surfaces, magnetic axis, and plasma boundary.
- A radial plot of p(ψ) and q(ψ).
- I_p ≈ 11.5 MA, β_N ≈ 1.5 in the status line.

## 4. Verify against the literature

Click **Validation**. You'll see a table of canonical references: ITER, DIII-D, JET, NSTX, W7-X, LHD, TAE Norman, Soloviev. Click **run** on the ITER row. The Computed and Error columns fill in — error should be under the listed tolerance (typically 15%).

## 5. Explore the s-α diagram

Click **Ballooning**. Defaults scan s ∈ [0, 4] and α ∈ [0, 4] on a 17² grid. Click **Run s-α scan**. You get the textbook ballooning stability map (Wesson §6.6.5), with the marginal-stability boundary traced in yellow.

## 6. Find what matters

Click **Sensitivity**. Click **Compute sensitivities**. You get a ranked bar chart of which parameter (κ, δ, A, B₀, q_edge) has the largest elasticity for β_N. For ITER-class geometry, κ usually wins.

## 7. Prove your result is converged

Click **Convergence**. Click **Run convergence study**. We sweep n_radial ∈ {32, 64, 128, 256, 512}, fit the convergence order via Richardson extrapolation, and tell you the smallest grid that gives < 0.1% error.

That's a publication-quality plasma analysis in five tabs and under 20 seconds of total compute.
