  The FLASHForward project at DESY is an innovative plasma-wakefield acceleration experiment, aiming to accelerate electron beams to GeV energies over a few centimeters of ionized gas. These accelerated beams must be of sufficient quality to be used in a free-electron laser; achievable only through rigorous analysis of both the drive- and accelerated-beam's longitudinal phase space. The pulse duration of these accelerated beams is typically in the few femtosecond range, and thus difficult to resolve with traditional diagnostic methods. In order to longitudinally resolve these very short bunch-lengths, it is necessary to utilize the properties of a transverse RF deflector (operating in the hybrid electromagnetic mode, HEM11), which provides a relation between longitudinal and transverse co-ordinates. It is proposed that this type of device, commonly known as a Transverse Deflecting Structure (TDS) due to its 'streaking' in the transverse plane, will be introduced to the FLASHForward beamline in order to perform these single-shot longitudinal phase space measurements. The initial investigations into the realization of this diagnostic tool are outlined.
