The vacuum control system design in ultracentrifuge chamber
نویسندگان
چکیده
The ultracentrifuge rotor usually works at 30,000 r/min or more, so centrifuge chamber must maintain a high vacuum to reduce friction of rotor and air. The paper described the vacuum control system design based on MSP430 microcontroller. The system included the MCU, sensors, measurement and conditioning circuitry, vacuum control circuit, power circuit components and so on. Tests proved that the system is stable and reliable performance to meet the ultracentrifuge vacuum measurement and control targets. © 2011 Published by Elsevier Ltd.

Effectiveness of Bench Top Non-Vacuum Autoclaves on Dental Turbine Chamber Sterilization
Introduction: Dental turbine chamber is a suitable reservoir for living microorganisms, so chamber sterilization is necessary for reducing cross contamination risk. On the other hand, in non-vacuum autoclaves, steam penetration into turbine chamber is doubtful, while they are still in use in dental clinics. In this study, performance of small non-vacuum autoclave in turbine chamber sterilizatio...
متن کاملEffect of Vacuum Chamber Eddy Current and Compensation by Digital Feedback
Measurement of the effect of the eddy current induced in the APS storage ring vacuum chamber by the storage ring sextupole magnet and its compensation using digital feedback with proportional, integral, and derivative (PID) control algorithm are presented. The magnetic field in the vacuum chamber shows strong quadrupole and sextupole components varying with frequency, in addition to significant...

متن کاملDesign of a Highly Optimised Vacuum Chamber Support for the Lhcb Experiment
The beam vacuum chamber in the LHCb experimental area passes through the centre of a large aperture dipole magnet. The vacuum chamber and all its support systems lie in the acceptance of the detector, so must be highly optimised for transparency to particles. As part of the upgrade programme for the LHCb vacuum system, the support system has been re-designed using advanced lightweight materials...
