Figure 5
Graphs showing the temperatures of both cold and warm components recorded for ~13 h starting with cooling of the BNP. The zoomed-in regions (b) and (c) show that both the warm and cold components achieved reasonably stable status after ~2.5 h, with temperature changes between 200-800 min shown in (d) and (e). These measurements assure that the specimen can be kept below 110 K during cartridge changes, and for longer-term storage inside the vacuum chamber of the instrument. Temperature stability is also required to minimize specimen drift due to thermal expansion.  [article HTML]
