“…1(a). This is similar to the observations made by Frederickson 16 and Hartman et al 17 In Fig. 3(c), we subtracted the signal for zero gap, representing the case with no air above the interdigits (detector covered with glass plate with no separation in between them).…”

We demonstrated the potential of TFID detectors for kilovoltage dosimetry and we defined its optimal geometry. For digits made of the same material and for digit width equal to the separation between them, we found that the thin-film detector has optimal performance when the distance between the digit centers is about 1 mm, while in the fixed digit width cases we observed that the signal is higher when their edge-to-edge separation is as small as possible.

“…The value of g rad can be obtained accurately from the experiment without employing a theoretical estimate by measuring dI/dt at t = 0 or, equivalently, by adjusting g rad in the theoretical calculations to fit the experimentally measured slope dI/dt at t = 0 [6].…”

An internal charging code, which is called NUMerical InTegration, has been used on many occasions to study the charging and discharging characteristics of dielectrics in space. The capabilities and limitations of the code are reviewed in this paper. In particular, the basic assumptions of the model are briefly discussed, and an example for the internal charging in the Juno environment is presented.

“…The response was recorded with a Faraday Cup. It can be seen in figure 7 that the electron energy peaks at around [19][20] MeV for both spectra and falls rapidly above 25 and below 10 MeV. The spectrum was measured between 5 and 30 MeV.…”

We performed measurements of the prompt radiation induced conductivity in thin samples of Kapton (polyimide) at the Little Mountain Medusa LINAC facility in Ogden, UT. Three mil samples were irradiated with a 0.5 µs pulse of 20 MeV electrons, yielding dose rates of 1E9 to 1E10 rad/s. We applied variable potentials up to 2 kV across the samples and measured the prompt conduction current. Analysis rendered prompt conductivity coefficients between 6E-17 and 2E-16 mhos/m per rad/s, depending on the dose rate and the pulse width. 4 ACKNOWLEDGEMENTS
