The advantages of using liquid helium as the investigative fluid in Rayleigh-Benard experiments are reviewed. A low temperature shadowgraphy apparatus is described that permits convective flow pattern visualisation in liquid helium, thus overcoming t

Low temperature detectors necessarily require low temperature instruments. Constructing good low temperature instruments requires information on the properties of materials used in their construction, in particular the thermal conductivity. Unfortuna

Semiconductor bolometers and microcalorimeters operating at ultra‐low temperatures are used in many applications, such as sub‐millimetre and X‐ray astronomy, dark matter searches, and double beta decay experiments. Various thermistor materials

Cryogenic instruments usually require components with high thermal conductivity. Pure (non alloyed) copper offers very high conductivity, but is soft and not thus always suitable structurally. High conductivity beryllium copper (BeCu) alloys are a co

While liquid helium is an ideal fluid for obtaining precise thermal information on mean convective flow in Rayleigh-Benard geometry, flow pattern details have until now only been measurable with room temperature fluids. We show that it is now possibl

An unusual periodic flow state has been observed in a normal liquid3He−4He mixture in a cylindrical container. This state exhibits “saw-tooth” temperature oscillations with a recovery time two orders of magnitude faster than the vertical therma

Convection experiments in helium, unlike those at room temperatures, have generally been limited to measuring mean flow characteristics. Following Sullivan et. al. flow patterns in convecting liquid helium have been shown theoretically to be no more
