| Jun 28, 2013 at 2:05 | comment | added | Connor Wolf | Basically, when you're working with cryogenic systems, you can get significant and problematic thermal leakage along any mechanical connections between your cold-stage and any vacuum feedthroughs, which are typically at ambient temperature. Considering that you rarely have more then 1/2-1W of thermal capacity on the cold-head most cryopumps (note - I'm ignoring intermediate stages here), even the thermal conduction along a thin copper wire between the cold-head and ambient can significantly degrade your thermal performance. | |
| Jun 28, 2013 at 2:02 | comment | added | Connor Wolf | @AnindoGhosh - I think you meant to ask me, not Scott. It seems there are multiple things called "cryowire". There is the audiophile hocus-pockus you mentioned, and there is wire for cryogenic uses, which is colloquially called "cryowire", at least in the lab I work at. Basically, it's wire that tries to maintain high electrical conductivity, while having low thermal conductivity. | |
| Jun 27, 2013 at 10:29 | comment | added | Anindo Ghosh | @MartinJ.H. Wires which have been through multiple cycles of cryogenic (ultra low temperature) treatment. Some audiophiles believe this improves the quality of sound from an audio system. Some audiophiles probably also believe in tidal effects of the moon on phase shift in an amplifier. | |

Status update, adressed some comments.

| Jun 27, 2013 at 7:55 | comment | added | Martin J.H. | @ScottSeidman I do worry about thermovoltages, but I think the inner conductor is stainless steel as well. Basically everything that sees a temperature gradient is either non-conducting (G10) or stainless steel (cables, beam tube). | |
| Jun 26, 2013 at 23:11 | comment | added | Connor Wolf | @ScottSeidman - Because if you're trying to connect to a sensor in a dewar, you would use cryowire. Stainless coax is a pain in the ass to work with, and I really doubt anyone would use it if they don't have to. | |
| Jun 26, 2013 at 23:09 | comment | added | Scott Seidman | @ConnorWolf -- how do we know this is an RF job, and not something like a sensor? | |
| Jun 26, 2013 at 22:56 | comment | added | Connor Wolf | What surface prep have you done? You likely need to lightly sand the surface you are planning on soldering to. | |
| Jun 26, 2013 at 22:55 | comment | added | Connor Wolf | @ScottSeidman - No. The DC bias the thermocouple produces will not affect the RF content. The system almost certainly has DC blockers in it too, anyways. | |
| Jun 26, 2013 at 22:45 | comment | added | Scott Seidman | Do you need to think about the thermocouple you're creating? | |

| Jun 26, 2013 at 12:57 | comment | added | Martin J.H. | I thought about crimping, but crimping to the shield is tricky. | |
| Jun 26, 2013 at 12:52 | comment | added | user3624 | I would crimp it instead of soldering. But then again, I have never used SS for this so I could be completely wrong. | |
| Jun 26, 2013 at 12:36 | comment | added | Andy aka | Not all stainless steels are non-magnetic and those that are non-magnetic to magnets don't always exhibit this "neutrality" when operated in AC mag fields upwards of 50kHz. | |
