Pre-ionization of argon in the capillary at the SIGNAL accelerator

The accelerator SIGNAL [1] is used to study electric discharges in an argon-filled capillary. The discharge current is 20...50 kA and the current rise time equals 30...50 ns. The pre-ionization system is used to create the pre-ionized gas. The pre-ionization current is 10...15 A. The paper describes...

Zusammenfassung:The accelerator SIGNAL [1] is used to study electric discharges in an argon-filled capillary. The discharge current is 20...50 kA and the current rise time equals 30...50 ns. The pre-ionization system is used to create the pre-ionized gas. The pre-ionization current is 10...15 A. The paper describes the system design and experimental conditions. State of argon medium after the pre-ionization pulse studied with the help of streak-, digital photo- and pinhole cameras is characterized. Instability development was not observed.
