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

XPS of Arradiance Samples F O C Al Sample%O%Al%F%C ARR ARR ARR Samples are practically identical according to XPS

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

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

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

O Sn Ca C Si*, Sb, As O* Ca As Sb Sn 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 B33 Float Glass

This Week Will continue testing Al 2 O 3 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.
