Possibilities • Compare the performance between the heat cleaning and atomic hydrogen cleaning Study on the cleaning procedure for the GaAs. Compare the performance of the heat cleaning and atomic hydrogen cleaning. Aim to develop the effective cleaning process for the GaAs using as a photocathode for accelerator.
Possibilities • Options • Show re-clean XPS data • Compare between bulk and Strained GaAs • Activate by using NF3 and O2 • Number of activation • First draft: end of May J. Vac. Sci. Techno. 9(6) 2991
Possibilities 2. Stability of the QE of the GaAs photocathode J. Appl. Phys. 80 (5), 1 September 1996
Possibilities • Work on the ALICE photocathode preparation system. • Fist draft : end of July O2 injection
Possibilities • Work on the surface science analysis system J. Appl. Phys. 80 (5), 1 September 1996
Possibilities • Options • Activate by NF3 • Recovery behaviour • Strained GaAs Applied Surface Science 99 (1996) 361-365
Possibilities 3. Conclusion paper Describe the GaAs photocathode study and activity at the lab. Show the performance of the ALICE photocathode reparation system and our surface analysis system. Discuss on how to prepare and handling the GaAs photocathode.
