Comparison of experimental charge collection waveforms with PISCES calculations

Calculations of the charge collection transient, performed using PISCES v5.0n (Aerospace modified) are compared with previous experimental measurements for energetic He, B, Si, and Fe ions incident on 1, 3, and 10 ohm-cm silicon diodes. Lumped circuit elements are used to represent resistances, capacitance, and inductance attached to the charge collection region. PISCES does not satisfactorily reproduce the changes in the charge collection waveform that occur when bias voltage, ion, or resistivity is changed.<
