File name life_mtbf1.pdf iSource+TM Rubidium Clock Lifetime and MTBF Data November 2014 LPFRS / RMO / STARLPRO / LNRClok / GRClok Rubidium Clock Lifetime and MTBF Contents Life Time ... 1 MTBF Calculation ... 3 LPFRS / RMO ...3 StarLPRO / LNRClok / GRClok ...3 Life Time The aging of the Rb lamps due to the diffusion of rubidium metal into the glass walls of its bulbs, has been previously studied by Mr, C.-H. Volk and Mr, R.-P. Frueholz, of Aerospace Corporation, CA, USA. These studies have been carried out using the differential scanning calorimetry technique. The calorimetric technique measures the elemental Rubidium content in a lamp used in normal conditions. TNT is using the SCHOTT glass 8436 type, which has been proved to be presently the best alkali resistant glass on the market . The figure 1 shows the rubidium consumption of a lamp made of SCHOTT 8436 glass, and shows a logarithmic curve of the rubidium consumption, which is approximately 100 |
