Module Contents
---------------

.. py:function:: get_paschen_curve_air()

   Get experimental Paschen curve data for air.

   .. warning::
      Data is AI generated/compiled, not ready for production.

   Classic breakdown voltage data as a function of pressure-distance product.
   Data compiled from Lieberman & Lichtenberg "Principles of Plasma Discharges
   and Materials Processing" and Raizer "Gas Discharge Physics".

   :returns: * **pd_torr_cm** (:py:class:`ndarray`) -- Pressure-distance product in Torr·cm
             * **V_breakdown** (:py:class:`ndarray`) -- Breakdown voltage in V
             * **V_breakdown_per_d** (:py:class:`ndarray`) -- Breakdown field E = V/d in V/cm (assuming d = 1 cm)

   .. rubric:: Notes

   Standard conditions: Temperature = 300 K, air at STP
   Paschen minimum typically occurs around 0.5-1 Torr·cm for air.


.. py:function:: get_gs_transition_data()

   Get experimental spark breakdown field data (Glow-to-Spark transition).

   .. warning::
      Data is AI generated/compiled, not ready for production.

   Spark breakdown electric field as a function of pulses per molecule during
   gas residence time. Shows transition from single-pulse spark breakdown to
   DC spark breakdown with field enhancement effects from electrode geometry.

   Source: Figure 6-10 - Average electric field (V/d) for G-S (Glow-to-Spark)
   transition as a function of pulses seen by a molecule during residence time.

   :returns: * **pulses_per_molecule** (:py:class:`ndarray`) -- Number of pulses per molecule: fD/v (dimensionless)
             * **spark_field** (:py:class:`ndarray`) -- Spark breakdown electric field in kV/cm
             * **spark_field_error** (:py:class:`ndarray`) -- Error bars on electric field measurements in kV/cm
             * **dc_spark_field** (:py:class:`float`) -- DC spark breakdown field (asymptotic value) in kV/cm

   .. rubric:: Notes

   - Single-pulse spark breakdown: ~23-25 kV/cm (left plateau)
   - DC spark breakdown field: ~5 kV/cm (right asymptote, red line)
   - Transition shows memory effect: accumulated ionization from repeated
     pulses reduces the required breakdown voltage
   - Field enhancement factor β_field present due to electrode geometry
   - This validates RepetitivePulseBreakdownModel with field enhancement


.. py:function:: get_temperature_effect_data()

   Get temperature dependence data for breakdown voltage.

   .. warning::
      Data is AI generated/compiled, not ready for production.

   :returns: * **temperatures** (:py:class:`ndarray`) -- Gas temperatures in K
             * **V_breakdown_normalized** (:py:class:`ndarray`) -- Breakdown voltage normalized to 300 K value

   .. rubric:: Notes

   Theoretical temperature correction: V_b ∝ √(T_ref/T)
   Limited experimental data available in literature.
