IDL Pulser
High Voltage - Subnano Second Pulser
The IDL pulser is the next generation of a compact high voltage and high speed pulser.
It can generate pulses up to 1500V with a rise time of 200 pico seconds and pulse width below 1ns. The average jitter between trigger and pulse is below 100ps.
The unit was tested on a wide range of temperatures and can operate down to -45°C without any issues.
In normal operation the pulser generates a pulse every 1 second, with its internal controller, but it can be triggered through an external TTL signal. In addition, a communication interface can change the internal trigger time and turn off its power supply for energy savings.
So far the pulser was used for ARA and HighCal at the South pole and RNO-G in Greenland.
