Winterover '20-21 here (there are other WOs on HN). We call it "driller tape" because it's was used all the time when the strings were installed (i.e. during drilling). Generally useful stuff for sticking things outdoors, though you do need to be quick with it. We also have a lot of teflon coated cable on station because everything else goes rock solid within a few minutes in winter. I rewired a bunch of people's heated goggles with that stuff (with an adapter for an off-head battery) because the factory cabling would break. However it's not made by 3M, the stuff we have at Pole now is Nitto P-212 [0][1]. It's possible we or other experiments used 3M in the past - given it's been a decade since we broke the ice - but the stuff on station definitely has that blue/white branding on the inside of the roll. Just to give an idea of how oddly stringent we are down there, and how experimental a lot of this is - regular things break all the time even in relatively controlled environments. Simple solutions like that tape are preferred where possible. The year before I wintered, the IceCube summer crew had to replace over 100 PSU fans in the cluster with equivalent Noctuas because the OEM ones would fail weekly. We did the same with DOM power supplies - I think we use exclusively Meanwell now. Never had any issues with those in my deployment, so it made quite a big difference. It's a harsh continent :) [0]: https://www.nitto.com/eu/en/products/e_parts/heat_resistant0... [1]: https://www.cambridge.org/core/journals/annals-of-glaciology... |
