chihiro 0.2.0

Spectral-geometric plasma confinement diagnostic

chihiro

Spectral-geometric plasma confinement diagnostic.

Zero free parameters. Sub-10 ms diagnostics. Built on the Davis Field Equations framework.

Installation

pip install chihiro

Quickstart

import chihiro

# Analytic model equilibrium
eq = chihiro.from_params(r_major=6.2, a_minor=2.0, b_toroidal=5.3,
                          i_plasma=15.0, beta_n=1.8)
result = chihiro.diagnose(eq)
print(result.status)       # "GREEN", "YELLOW", "ORANGE", or "RED"
print(result.spectral_gap) # λ₁ of the CHT operator
print(result.c_max)        # Plateau capacity C_max

# Load a G-EQDSK file
eq = chihiro.load_geqdsk("g175844.03100")
result = chihiro.diagnose(eq)
