A number of characteristics in the soft X-ray range are presented including linearity, calibrations conducted with a photodiode and a gas monitor detector as well as ultra-high-vacuum compatibility tests using residual gas analysis. The application of these power meters for LCLS-II and other X-...
The RF waveguide is connected to one port and a vacuum pump to the second. For diagnostic purposes, an RF monitoring loop is also located in the second port. The photocathode is located at the geometric center of the end plate of the half-cell. The end plate is removable to facilitate ...
