Summary: | The AWAKE facility uses novel proton beam-driven
plasma wakefields to accelerate electron bunches over 10 m
of Rubidium plasma. Precise monitoring of 2 diverse beam
types necessitates an electron beam position monitor (BPM)
working in a frequency regime of tens of GHz. A high frequency conical button-style BPM with a working regime
of up to 40 GHz has been investigated as a way to discriminate the electromagnetic fields of 19 MeV, 4 ps electron
bunches propagating spatially and temporally together with
a 400 GeV, 170 ps proton bunch in the AWAKE common
beamline. The sensitivity of the HF BPM to the electron
beam position is determined under various beam conditions,
with both electrons and protons, and integration with a TRIUMF front-end is discussed.
