Where each column comes from
rest_parameters averages the -rest.txt over [t_onset, t_onset + 0.3 s],
the decay window:
| Column | Source | Note |
|---|---|---|
tauE_TOT_ms |
tau_tot (AUG's TOT diagnostic) |
the "official" τ_E; values outside 5 to 500 ms are dropped |
H_TOT |
H/L-facs;8 (TOT) |
judging by its values (0.6 to 1.1) it is the H98(y,2) factor; still to be confirmed with Germán |
tauE_W_ms |
Wmhd / P_loss |
our own cross-check; P_loss = P_ECRH + P_NBI + P_OH − dW/dt |
tau98_ms, H98_calc |
IPB98(y,2) scaling | nominal AUG geometry (AUG_GEOMETRY: R = 1.65 m, a = 0.5 m, κ = 1.65, M = 2) and nedl_H1 as the line density |
I_RMP_kA |
IBu1 |
current in upper B coil 1: ~0.9 to 1.2 kA in the RMP shots, ~0 elsewhere |
P_ECRH_MW, P_NBI_MW, P_OH_MW, Ip_MA, Bt_T, ne_line_19, Wmhd_kJ, Zeff |
-rest.txt |
profile_gradients uses the -lboN.txt closest to the injection (IDA
profiles, poloidal ρ; dt_lbo_s = t_profile − t_onset, up to ±0.6 s):
| Column | Definition |
|---|---|
ne0, Te0 |
value on axis (1e19 m⁻³, keV) |
ne_ped, Te_ped |
value at ρ = 0.90 (≈ top of the pedestal) |
gradne_edge, gradTe_edge |
linear slope dX/dρ over 0.90 ≤ ρ ≤ 0.98 (negative = falls outward) |
gradne_edge_m, gradTe_edge_m |
the same per meter, with dr ≈ a·dρ (approximate) |
a_Lne_core, a_LTe_core |
a/L = −(1/X) dX/dρ averaged over 0.3 ≤ ρ ≤ 0.7 (peaking) |
Why TOT and not only W/P
tau_tot already accounts for what the TOT diagnostic includes (absorbed
power, dW/dt). tauE_W_ms agrees with TOT to within ~10 % in every group,
which confirms how the columns are read. Computed H98 and H_TOT agree in EDA
and I-mode but not in RMP (H98_calc ≈ 1.3 vs. 0.8): with 6 MW of NBI at low
density, part of the NBI power is not absorbed (shine-through, fast ions lost
with RMP), and the simple calculation counts it anyway.
Before 0.4.0 the columns after Zeff were shifted (see the
changelog).
