Figures

Image of FIG. 1.
FIG. 1.

Schematic drawing of the experimental setup at the JETI system including the electron beam generation, the beamline, and the online beam monitoring system (not to scale). The electrons propagate in air at a distance of about 220 mm.

FIG. 2.

(a) Exemplary dose distribution measured with a radiochromic EBT-1 film over the whole 35 mm beam diameter and the cell covered area (black dashed square) irradiated with a dose of (2000 pulses). The corresponding color scale is also shown. (b) Dose distribution determined for two lateral sections vertical and horizontal across the center of the sample area, delimited by the dashed lines. The cross-sectional directions were also displayed in the left picture.

Image of FIG. 3.
FIG. 3.

Actual doses at cell position compared to the number of applied laser pulses individually for both experimental days. The arrows mark two outliers due to different pumping rates and corresponding vacuum conditions. Dose errors were calculated by error propagation; fit parameters are given in text.

Image of FIG. 4.
FIG. 4.

Accumulated relative dose (a) and total voltage (b) measured during the irradiation and compared to the absolute doses determined retrospectively by means of EBT-1 dosimetry films. Completely (gray) and half-filled samples (black) were distinguished in the graph, whereas the linear fits were performed with all data. Displayed errors are statistical errors, calculated by error propagation.
