Beamline components
RF current monitoring for machine protection.
Dymenso developed radio-frequency cavity average current monitors for the LCLS-II project at SLAC National Accelerator Laboratory.
Machine protection
Current measurement becomes a beam-power limit.
The LCLS-II upgrade adds a 4 GeV continuous-wave superconducting linear accelerator within the first kilometer of the SLAC linac tunnel, supplementing the existing pulsed accelerator.
Average current monitors are positioned where beam energy is known or constrained. The system calculates beam power from measured current and known energy, then trips the beam when power exceeds the permitted value—protecting downstream beam dumps from excessive loading.
An RF cavity sensor monitors average electron-beam current.
Current is combined with the known beam energy at the sensor location.
The safety system interrupts the beam when calculated power is too high.
Component engineering
RF, thermal, and mechanical behavior resolved together.
The ACM program connected electromagnetic performance to mechanical design, thermal response, fabrication, assembly, and RF test.
