| - | **New feature**: a combined temperature-voltage sweep can be done using the keyword ''Temperature-Voltage'' in the field ''<SweepType>'' of ''<SweepParameters>'' (see the example of code below). In this case, the simulation can be parallelized. ''<Threads>'' defines the number of parallel threads. Its optimal value should be the number of CPU cores available (if the available memory is sufficient). Within each parallel temperature sweep, a serial voltage sweep is performed. | ||
| - | |||
| - | <code> | ||
| - | <SweepParameters> | ||
| - | <SweepType>Temperature-Voltage</SweepType> | ||
| - | <MinV> 50</MinV> | ||
| - | <MaxV> 60</MaxV> | ||
| - | <DeltaV> 2</DeltaV> | ||
| - | |||
| - | <MinT> 25</MinT> | ||
| - | <MaxT> 300</MaxT> | ||
| - | <DeltaT> 25</DeltaT> | ||
| - | |||
| - | <Threads>12</Threads> <!-- Parallelization for Temperature-Voltage sweep --> | ||
| - | </SweepParameters> | ||
| - | </code> | ||
| - | Note that for such voltage-temperature sweep, ''<Maximum_Number_of_Threads>'' in ''<Simulation_Parameter>'' should be set to ''1''. (A combined parallelization will result in lower performances.) | ||
| - | <code> | ||
| - | <Simulation_Parameter> | ||
| - | ... | ||
| - | <Maximum_Number_of_Threads>1</Maximum_Number_of_Threads> | ||
| - | </Simulation_Parameter> | ||
| - | </code> | ||
| - | |||
| - | |||
| - | At the end of the simulation, current and gain maps can be displayed. | ||
| - | ''Gain_map.fld'' gives the maximum gain at each (voltage,temperature) point. | ||
| - | ''Max_Gain_frequency.fld'' gives the map of the corresponding photon energy for which the gain is maximum. | ||
