Change in cell voltage during galvanostatic operation as a function of the absorbed X-ray energy of the CCM (1 J cm−2 78 kGy) in (a) overview and (b) details up to 1.0 J cm−2; with (c) corresponding real part of 1 kHz and (d) 10 kHz cell impedance; above 1.33 J cm−2 the beam-off time of the 10% beam cell was reduced to 10 s due to a programming error and beam-off voltage decay becomes invisible on that scaling. |
