      abstract     = {Introduction: FLASHlab@PITZ is a new $R\&D$ facility for
                      radiationbiology studies (≤22 Mev, electrons) and is being
                      setup at the PhotoInjector Test facility at DESY in Zeuthen
                      (PITZ). It provides worldwideunique beam parameters
                      regarding delivered dose and dose rate [1].With an average
                      dose rate within one pulse of up to 109 Gy/s and peakdose
                      rates up to 4 × 1013 Gy/s, PITZ is fully capable of
                      ultra-high doserate experiments, for example the
                      investigation of the FLASH effect.Furthermore, clinical dose
                      rates of 0.05 Gy/s are also available at PITZ.Materials $\&$
                      Methods: Dosimetry at such high dose rates is a
                      majorchallenge. Traditional detectors suffer from saturation
                      and cannotprovide reliable measurements up to such high dose
                      rates. Thecommercially available ionization chamber PPC05
                      (Markus type, IBADosimetry) was tested for online dosimetry.
                      The dose per pulse can bemodified by adjusting the number of
                      micropulses within a pulse.Results: By increasing the number
                      of micropulses within a single pulseup to 400, a maximum
                      dose per pulse of 64 Gy was delivered. Chargecollection
                      efficiency from 0.16 Gy/pulse up to 64 Gy/pulse wasmeasured
                      for four different bias voltages from 100 V up to 400 V
                      (seefigure 1).Summary: The PITZ accelerator provides a
                      worldwide uniqueparameter space for radiation biology
                      studies. The number ofmicropulses within a pulse is
                      tuneable. The ionization chamberPPC05 was irradiated with up
                      to 64 Gy/pulse and the charge collectionefficiency was
                      measured},
