Secondary electron emission from accelerator materials
Motivations gained from this paper are: (1) Suppress electron emission from high rf surface field components, e.g., SPEAR storage ring cavity tuners (1973), (2) Find a coating for superconducting Nb oxidation prevention (1980), (3) Develop a simple method for TiN-coating of LER Al alloy beam chambers (1998), and (4) Measure yields as a function of primary electron incidence angle, for simulating of the electron cloud effect (1999). Conclusions drawn from data: (1) Most electron-generated secondaries will have low energy ({approximately}4 eV) and <1 yield, (2) TiN is effective at reducing the yield of Al, (3) Electron removal (conditioning) of H{sub 2}O and HCs works (but probably leaves carbon in technical vacuum), and (4) The yield increase with primary electron beam angle is about that expected.
