I've heard various interesting effects for JEOL H type spectrometers (100 mm FC) with the TAP crystal. Would someone be willing to post some scans of say Al Ka and Kb on say Al2O3? A scan that includes both the Al Ka and Al Kb would be most interesting. I obtain these L-units for the two lines so a single scan that includes both emission lines would be ideal.
al ka on TAP (140 mm), is 90.90472 (with refractive index correction, k= 0.00218)
al kb on TAP (140 mm), is 87.0001 (with refractive index correction, k= 0.00218)
These lines should both be above the lower limit on these spectrometers. And if possible a comparison with the normal 140mm spectrometer TAP crystal for Al Ka/Kb also.
Thanks!
