“…The film was 25 μm in thickness and metallized with a very thin layer (around 70 nm) of aluminum in one side. The DuPont film was cut in samples of 50 mm × 360 mm, which were treated in two PIII experimental systems (3IP-LAP and 3IP-CE) reported elsewhere (10,11) . The samples were put in the treatment chambers using a stainless steel tube 11 cm of diameter, 20 cm in length, and 2 mm in thickness as the sample holder.…”

To date, there are relatively few studies on polymer applications in space, especially those related to the evaluation of the dielectric breakdown resistance in the space environment. Polyimide (Kapton TM ) is extensively used in space in the thermal control of satellites but as a soft material subject to the aggressive space environment, it experiences degradation of properties during its lifetime. One property commonly affected in space is the surface electrical breakdown strength. The accumulation of charges on the surface of the Kapton occurs due to the formation of low-density hot plasma around the surface and due to the bombardment by highly energetic charged particles from space. The accumulation of charges can lead to deleterious electrical discharge on the surface of the material. In this study, aluminized Kapton, in the form of a film, has been treated by nitrogen plasma immersion ion implantation (PIII) inside a metallic tube. Mesh assisted and non-mesh assisted PIII have been tested. The influence of the ion implantation on the surface electrical breakdown strength of the treated samples has been determined using Weibull probability distribution function. The morphology of treated samples has been characterized by Atomic Force Microscopy. Results of the PIII treatment on morphology and surface electrical breakdown strength of Kapton are presented and discussed in this paper.

“…Therefore, it is indispensable to improve the attributes of the inner walls of such tubes. In this respect, several investigations have been performed [2][3][4][5][6][7][8][9][10]. Fujiyama et al proposed coaxial magnetron pulsed plasma (CMPP) and double-ended coaxial magnetron pulsed plasma (DCMPP) methods for coating the inner walls of narrow tubes with the aid of the extended anode effect [11].…”

The double-ended coaxial magnetron pulsed plasma (DCMPP) method with auxiliary outer anode was introduced in order to achieve the uniform coating of non-conductive thin films on the inner walls of insulator tubes. In this study, titanium (Ti) was employed as a cathode (sputtering target), and a glass tube was used as a substrate. In an argon (Ar) and oxygen (O 2) gas mixture, magnetron plasma was generated. Oxygen gas was introduced to deposit a titanium oxide (TiO 2) film. A comparison between films coated with and without an auxiliary outer anode was made. As a result, it was clearly shown that the DCMPP method using an auxiliary outer anode enhanced the uniformity of the deposited non-conductive film compared to the conventional DCMPP method. Moreover, the optimum conditions under which the thin TiO 2 film was deposited on the inner wall of the glass tube were revealed. From the results, it was supposed that the auxiliary outer anode contributed to the uniformity of the distributions of deposited negative charge on the non-conductive film and consequently the electric field and the plasma density uniform.

Tuning the electronic properties of transition‐metal and rare‐earth compounds by virtue of changes of the crystallographic lattice constants offers controlled access to new forms of order. The development of tungsten carbide (WC) and moissanite Bridgman cells conceived for studies of the electrical resistivity up to 10 GPa, as well as bespoke diamond anvil cells (DACs) developed for neutron depolarization studies up to 20 GPa is reviewed. For the DACs, the applied pressure changes as a function of temperature in quantitative agreement with the thermal expansion of the pressure cell. A setup is described that is based on focusing neutron guides for measurements of the depolarization of a neutron beam by samples in a DAC. The technical progress is illustrated in terms of three examples. Measurements of the resistivity and neutron depolarization provide evidence of ferromagnetic order in SrRuO3 up to 14 GPa close to a putative quantum phase transition. Combining hydrostatic, uniaxial, and quasi‐hydrostatic pressure, the emergence of incipient superconductivity in CrB2 is observed. The temperature dependence of the electrical resistivity in CeCuAl3 is consistent with emergent Kondo correlations and an enhanced coupling of magneto‐elastic excitations with the conduction electrons at low and intermediate temperatures, respectively.
