Abstract :
A future electron-positron linear collider with c.m. energy in the range of 3-5 TeV is understood to require an operating RF frequency in the range of 30-100 GHz. Higher operating frequency can lead to higher acceleration gradient, with a corresponding smaller accelerator length. This paper describes a test structure designed to determine the maximum achievable accelerating gradient for an operating frequency of 34.272 GHz. The ~6-cm long test structure consists of 21 cells operating in the 2π/3 mode. It is to be driven using a magnicon amplifier, designed and being built by Omega-P, with a design power of over 40 MW in a 1 μsec pulse. Preliminary calculations indicate that this should make it possible to test the structure to accelerating gradients of over 300 MV/m
