Tunka Pulser
Siberia, Russia
For calibration of antennas for a Radio Air Shower Array, the IDL constructed a high-voltage calibration unit.
The Tunka pulser delivers short pulses (10s of ns) which deliver broad-band energy for calibration.
The unit also has frequency synthesizers to generate CW signals, also useful for characterizing detector systems.
Autonomous operation, without a computer, was required. The pulser has its own display and 4-button keyboard for setting variables.
The Tunka project is located SW of Lake Baikal in Siberia, Russia.
Dave Besson is PI of this project.
