Discussion Overview
The discussion revolves around finding affordable conductive paste suitable for use in vacuum environments, specifically for an accelerator application. Participants explore the requirements for conductivity, outgassing characteristics, and potential alternatives to paste.
Discussion Character
- Exploratory, Technical explanation, Debate/contested
Main Points Raised
- One participant inquires about the specific application of the paste, asking whether it is for grounding or shielding.
- Another participant clarifies that the paste will be applied to an electrode energized with RF, intended to smooth over joints in a segmented electrode for an RFQ linac.
- Some participants express uncertainty about the suitability of paste, suggesting soldering as a potential alternative for joining the electrode pieces.
- One participant proposes the idea of using a space-compatible conductive epoxy, noting that the choice depends on required conductivity and outgassing specifications relative to temperature.
Areas of Agreement / Disagreement
Participants do not reach a consensus on the best approach, as there are competing views on the use of conductive paste versus soldering or epoxy. The discussion remains unresolved regarding the availability of suitable conductive pastes.
Contextual Notes
Limitations include uncertainty about the outgassing characteristics of copper and silver pastes, as well as the specific conductivity requirements for the application.
