Conclusion:

Conclusion: Ionization chambers capable of accurate measurements under FLASH conditions were found to have very small electrode spacing and high electric field strength (1000 V/mm). It was confirmed in this study that the principal dependencies that ion chambers have are on DPP and a new finding was their dependence on pulse width, which becomes negligible when reducing the electrode spacing and increasing the electric field strength.
