Experimental work is planned to study the performance
of a beam-driven cylindrical dielectric wakefield accelerat-
ing structure as a source of THz coherent Cerenkov radi-
ation (CCR). For an appropriate choice of dielectric tube
geometry and driving electron bunch parameters, the de-
vice operates in a single-mode regime, producing radiation
in the THz range. This source can potentially produce high
power levels relative to currently available sources, with
∼50 μJ radiated energy per pulse achievable using the elec-
tron beam currently in operation at the Neptune advanced
accelerator laboratory at UCLA ( ∼13 MeV beam energy,
∼200 μm RMS bunch length, ∼500 pC bunch charge).
Preparations underway for installation of the experiment
are discussed.
