Thirdly, an auxiliary vacuum cell is introduced round the SWS, and there are 6 vacuum pump ports in the auxiliary vacuum cell.
The pressure calculation for the vacuum cell compares the beam cleaning efficiency during the early commissioning stage when the accumulated beam dose attained 1 A h and 100 A h.
The auxiliary vacuum cell helps to inhibit the excessive pressure growth in the beam-wave interaction area during the HERP-MILO operation, and the 6 vacuum pump ports can enhance the vacuum pumping speed and efficiently reduce the vacuum recovery time.
Moreover, the experimental results also show that the array of round holes and the auxiliary vacuum cell can improve the vacuum condition of the HERP-MILO, which is favorable for the increase of the duty cycle, the pulse repetition rate and the cathode lifetime of the HERP-MILO.
Micro-Raman and PL measurements were performed at room temperature employing a vacuum cell equipped with an optical window.
This paper describes the design and fabrication of an atom chip to be used in ultra-high-vacuum cells for cold-atom tunneling experiments.
After 24 h, inoculum was removed using vacuum aspiration, cells were washed five times with PBS and 100 μl (96-well plate) or 500 μl (24-well plate) of fresh medium DMEM supplemented with 3% FBS and 0.1 mM NEAA was added in the presence of 2% DMSO.
When the SEM mode is changed from variable pressure to high vacuum mode, cells deflate but remain attached to the scaffold.
Vacuum-drying cells after suspension in selected polymers proved an effective method for screening the potential of polymers to improve the desiccation tolerance of rhizobia.
After correcting for membrane thickness, measured water fluxes in the FEC agree with those obtained in the vacuum-evaporation cell (VEC) validating the new FEC.
Fourier transform infrared spectroscopy (FTIR) spectra of samples before and after pyridine adsorption (Py-FTIR) were collected on a Nexus 670 FTIR equipment (Thermo Nicolet; Thermo Fisher Scientific Hudson, NH, USA) with a high-vacuum reaction cell (HVC) from Harrick Science (Harrick Scientific Products, Inc., NY, USA).
