Turbomolecular pump ( ‪#‎ TMP‬) is a popular high vacuum pump, that is widely used in many vacuum systems (electron microscopes for example) as it is clean, fast and efficient for maintaining high vacuum over a long period of time.Inside the pump there are rotor blades that rotate with a speed up to 90 000 rotations per minute and stator blades that are stationary. In 1957, Lewis D Hall, John C Helmer, and Robert L Jepsen filed a patent for a significantly improved pump, one of the earliest pumps that could get a vacuum chamber to ultra-high vacuum pressures. Working principle. The basic element of the common ion pump is a Penning trap.

cooled shell of the diffusion pump, the working fluid condenses and is recovered and directed back to the boiler. The pumped gases continue flowing to the base of the pump at increased pressure, flowing out through the diffusion pump outlet, where they are compressed to ambient pressure by the secondary mechanical forepump and exhausted.
