Space Charge Measurements of Polyimide Films
IEEJ Transactions on Fundamentals and Materials, 2004 Polyimide films have been commonly used in industries such as for an insulating material of a printed circuit board. We measured space charge profiles of a polyimide film under dc electric filed, and reported that charges were injected into the film under a dc electric field of 10 kV/mm.

Measurement and simulation of transverse Schottky noise with space charge
Physical Review Special Topics. Accelerators and Beams, 2008 The effect of moderate space charge on the transverse Schottky spectrum of a coasting beam is studied using measurements and simulations together with an analytic model. The measurements of transverse Schottky bands from heavy ion beams were performed in
