The technologies described include low-magnetic and ultra-high vacuum materials developed for use within the cryogenic probe.
For these positions CERN typically seeks individuals with backgrounds in physics, computer science, electronics, mechanics, cryogenics, ultrahigh vacuum, materials science, radiation protection, cooling and ventilation, civil engineering, operation of accelerators and associated equipment, and conventional and superconducting magnets.
After dried in vacuum, the material showed a light-yellow color (denoted as SUASi-SBA-15).
Its design optimization activity requires the vacuum vessel material to be non-magnetic, very strong and with low induced activation.
We limit our discussion to solution-processable materials, which now offer comparable performance, but potential processing advantages to vacuum sublimed materials, and to p-type devices, which tend to exhibit better environmental and operational stability.
Solution and reprecipitation phenomena are limited and a nanometric fraction of (Ti,Mo)(C,N) grains is retained in the microstructure leading to a significant increase in hardness with respect to vacuum sintered materials (from 11 to 14 GPa).
The overall sugar yield for the unwashed solids reached 93 and 77.5%, respectively for pressed and vacuum-filtered material.
However, the amount of mannose released in the slurry after the first step was 87.4% for both pressed and vacuum-filtered material.
The higher severity, together with the higher amount of soluble sugars in the liquid from the first step for vacuum-filtered material, resulted in higher sugar degradation.
When the pretreated slurry was washed between the two acid hydrolysis steps the glucose yield was about the same for pressed and vacuum-filtered material, 59% ± 1.5% (of that theoretically available in the raw material).
