Refrigerator cryopumps are gases by condensation and cryosorption on very cold surfaces. Since the gases are accumulated in the cryopump it has to be regenerated from time to time, depending on the gas flow. In many industrial processes, especially i

Muonium atoms have been observed emerging into vacuum from silica aerogel surfaces with a thermal velocity distribution corresponding to a temperature of 298(10) K after stopping positive muons from a subsurface muon beam. Yields up to 2.3(3)% could

To search for a long living 2S1/2 state in the muonic helium ion at helium gas pressures of 14 and 40 atmospheres, radiative muon transitions were registered in a time resolved mode using sodium iodide crystals. Special care was taken to avoid gas im

For the operation of a refrigerator cryopump a roughing pump is necessary to provide a sufficient low starting pressure prior to cool-down. Usually oil lubricated rotary vane pumps are used for that purpose. However, the demand for a fully hydrocarbo

According to the PNEUROP-acceptance rules for cryopumps the crossover is defined as the maximum amount of nitrogen (mbar I) which can be pumped by the cryopump within a short interval, whereby the temperature of the cryopanels must not exceed 20 K. M

Many manufacturing processes such as sputtering, ion implantation, MBE and others, rely heavily on cryopumping, mainly because of the inherent advantages such as an especially clean vacuum, very high pumping speeds with respect to water vapour and pr
