or via an adjacent vapor stream (venturi jet vacuum pumps). Turbomolecular pumps use a rotating disk with a series of rotors and flow stabilizing, stationary stators to impart a preferential motion to ...

This program is useful for visualizing approximations of energy band diagrams, and performing back-of-the-envelope calculations of their important parameters. Energy bands can be modeled at varying ...

[Mark Aren] purchased a pair of Turbomolecular pumps (TMP) sans controllers, and then built an FPGA based BLDC controller for the Turbomolecular pumps. A TMP is similar to a jet turbine ...
