A field emission retarding potential ferp is a method to measure the work function between two materials and can for example be used to verify the purity of a material. In order to obtain such a function of several samples a high vacuum environment is desired. At the lab of CTI a certain vacuum chamber with corresponding equipment already exist, bu...

... membrane/diaphragm pump Diaphragm pumps are single are multi dry compressing vacuum pumps and are therefore completely free of oil so they don't contaminate the vacuum chamber. The work- ing principle is shown in Figure 5. It uses a diaphragm that gets elasti- cally bended in a oscillating way by means of a connecting rod and an eccentric. ...
