X-rays from antiprotonic helium in helium gas [PDF]
Nuclear Physics A, 1982 Abstract X-ray transitions to the 4F, 3D, and 2P atomic levels of pHe have been observed with antiprotons stopped in He gas at 4 and 1.1 atm NT. The population by radiative transitions of the 3D level in gas Y M (4 atm ) = (28±14)% and Y M (1.1 atm ) = (43±22)% exceeds by more than one order of magnitude that measured in liquid He.

Speech alarm and cycle helium gas monitoring of helium refrigerator
Indian Journal of Cryogenics, 2014 Two helium liquefiers are running round-the-clock in parallel. One of them is always connected to the Superconducting Cyclotron in refrigeration mode. EPICS based alarm system is running with alert sound in computer speaker. But the fault cannot be located without opening the fault screen.

Helium Gas Scintillation [PDF]
Review of Scientific Instruments, 1965 A gas scintillation counter is described which operates to 40 atm pressure. An attempt was made to maximize the scintillation light output in helium. Helium scintillation properties studied with this counter include the effect of various wall-coating materials, gas-purity effects, the linearity of pulse height with energy, and the variation of pulse ...
