Liquid helium cryostat for esr measurements free from ...

Oct 01, 1985· The helium capacity is about 500 cm3 but only 300 cm3 of liquid helium keeps a sample at 4.2 K for 9 h when liquid nitrogen is added every 1 h. Therefore, this cryostat allows us to measure ESR spectra for the period of as long as 9 h without refilling liquid helium.

The Effect of Helium Sedimentation on Chandra X-ray ...

Recent theoretical studies predict that the inner regions of galaxy clusters are enriched by the sedimentation of Helium (He) ions into the cluster core. However, since He produces no lines at X-ray emitting temperatures, cluster masses are generally derived under the assumption that the He abundance is fixed at the Solar abundance value. In this talk we will present observational …
