Plateau voltage function.

First, the voltage is at U_off, then it rises to U_on in t_rise seconds, stays at U_on for t_on seconds, and finally falls to U_off in t_fall seconds.

Parameters:

  • t (float) – Time in seconds.

  • U_off (float, optional) – Voltage when the pulser is turned off, by default 0.0 V.

  • U_on (float, optional) – Voltage when the pulser is turned on, by default 10e3 V.

  • t_rise (float, optional) – Time to go from U_off to U_on, by default 3e-9 s.

  • t_on (float, optional) – Time to stay at U_on, by default 4e-9 s.

  • t_fall (float, optional) – Time to go from U_on to U_off, by default 3e-9 s.

Returns:

Voltage in V.

Return type:

float

Plateau electric field function.

First, the voltage is at U_off, then it rises to U_on in t_rise seconds, stays at U_on for t_on seconds, and finally falls to U_off in t_fall seconds. The electric field is calculated as E = U / d.

Parameters:

  • t (float) – Time in seconds.

  • U_off (float, optional) – Voltage when the pulser is turned off, by default 0.0 V.

  • U_on (float, optional) – Voltage when the pulser is turned on, by default 10e3 V.

  • d (float, optional) – Interelectrode distance, by default 3.0e-3 m.

  • t_rise (float, optional) – Time to go from U_off to U_on, by default 3e-9 s.

  • t_on (float, optional) – Time to stay at U_on, by default 0.1e-9 s.

  • t_fall (float, optional) – Time to go from U_on to U_off, by default 1e-9 s.

Returns:

Electric field in V/m.

Return type:

float

rizer.electric_circuit.pulser.DATA_FILE#
rizer.electric_circuit.pulser.experimental_electric_field(t: float, d: float = 0.003) → float#

Electric field function based on experimental data.

The electric field is calculated as E = U / d.

Parameters:

  • t (float) – Time in seconds.

  • d (float, optional) – Interelectrode distance, by default 3.0e-3 m.

Returns:

Electric field in V/m.

Return type:

float

Raises:

ValueError – If the voltage is not a float.

Notes

The datafile is defined outside the function to avoid reading it at each call.

rizer.electric_circuit.pulser.no_electric_field(t: float) → float#

Zero electric field function.

Parameters:

t (float) – Time in seconds.

Returns:

Electric field in V/m, always 0.0 V/m.

Return type:

float
