      abstract     = {Electron-bunch-driven plasma-wakefield accelerators promise
                      to revolutionise particle acceleration by providing compact
                      and cost-effective energy boosters for electron linacs which
                      could, for example, significantly enhance the photon
                      energies produced by free-electron lasers. The FLASHForward
                      facility at DESY has made substantial progress,
                      demonstrating that accelerated electron bunches can maintain
                      their charge, energy spread, and emittance during plasma
                      acceleration. A major challenge remains in achieving
                      high-repetition-rate operation, as is common in
                      radio-frequency accelerators.To be competitive with proposed
                      linear collider schemes and currently operating FELs,
                      average repetition rates on the order of 10 kHz are
                      required. Therefore, identical plasma acceleration events
                      must take place at high frequencies over a long period of
                      time. One of the important challenges is to deal with the
                      high heat load placed on the plasma cell by the plasma
                      formation process and the driving beam, which are similar in
                      terms of power deposition at FLASHForward. In this
                      contribution we report on recent efforts to characterise the
                      long-term heating effects arising in a discharge plasma
                      source operated at repetition rates up to 1 kHz. We will
                      present measurements of the time evolution of the discharge
                      plasma source and discuss the implications of these results
                      for sustained high-repetition-rate operation.},
