  1. Characterization of Arradiance Samples and B33 Float Glass Slade J. Jokela

  2. XPS of Arradiance Samples O • Samples are practically identical according to XPS F C Al

  3. SEY of Arradiance Samples • No clear trend between scans • Each scan was approximately 5 minutes long • Approximately 200nA (electrons) continuous

  4. SEY of Arradiance Samples • FFT Filtered (Low pass of 0.05 eV-1)

  5. SEY of Arradiance Samples • Average of 5 sequential scans • Each of the 5 spectra were FFT-filtered • Standard Deviation is shown • It would appear that each of these samples produces similar SEY

  6. B33 Float Glass • B33 was tested in early January • *Most likely candidate for visible peak(s) • Data is shifted by about 7eV due to insulating-nature of glass • Peak shift is not constant across entire spectrum due to insulating-nature of glass as well as chemical shifts • Sb and As will not be resolvable for this sample due to interference with both O and Si • B270 was not tested as a possible solution was found that determined which side of the glass was the float side O O* Ca As Sb Sn Sn C Ca Si*, Sb, As

  7. This Week • Will continue testing Al2O3 samples from our ALD group • MatSci Division ISM-Day on Friday • Troubleshooting and hopefully fixing the UV-light source • He plasma forms between anode and HV-input rather than between anode and cathode.
