*16, 20nC bunch train, steady output power of 148 MW and 56 MV/m peak gradient. The energy loss is 5.7 MeV for the last bunch in the bunch train .
*20nC, single bunch, bunch length 1.5mm.

Bench test results
26GHz TM01 mode launcher
Experiment is planned to perform at AWA facility.
beam simulation by Euclid self-developed code
Simulation using the DWA-BD-07 particle code of the longitudinal and transverse wake of a 20nC single drive bunch passing through the power extractor.
Snapshots of the electron distributions in the x-z plane traversing the 26GHz decelerator (five bunch train computed using DWA-BD-07). The frames top to bottom show bunches 1-5 at 40ps intervals. The bunches are injected with an initial offset of 0.4mm in the positive x direction. Initial energy of each bunch is 20MeV. Distances in cm; the vertical extent of each plot corresponds to the width of the vacuum channel (±0.35 cm).
Components developed for beam experiment.
WR-34 rf flange
26GHz power detector
Heterodyne rf detection circuit
26GHz SiC based rf load is under development.
