In a recent article by Alexander Dietrich and Jürgen Alex from the Paul Scherrer Institut, published in the CERN Courier, the authors delve into the critical importance of high-voltage pulse stability in klystron modulators, which are key components in free electron lasers such as SwissFEL. These modulators deliver high-voltage pulses, and any amplitude variations can significantly affect the performance of RF pulses.
The article introduces an innovative embedded system that uses the Red Pitaya STEMlab 125-14 board to simplify and enhance the accuracy of pulse stability measurements. This compact setup achieves a remarkable measurement precision down to 7–8 ppm, allowing for permanent live monitoring.
