Useful X-Ray Related Numbers
- Si a0 = 5.4308 Angstrom
- CeO2 a0=5.411 Angstrom
- Cd-109 gamma = 88.036 keV
- X-ray energy/wavelength conversion constant = 12.39842 Angstrom/keV
Useful 1-ID Operations Information
- Always set the undulator by closing from large to small gap.
- Always scan the Kohzu monochromator from high to low energy.
- A Cd-109 source that can be used to calibrate detectors can be obtained by contacting Ali. It has Ag flourescent lines and a 88.036 keV gamma line.
- Tim Mooney's telephone number is 2-5417.
Frequently Asked Questions
The following questions come up often when using the Sector 1 beamlines. If you have a question (and maybe answer) that would be of general interest to Sector 1 users, please give it to Jon or Greg for inclusion in this list.
Q: No matter what buttons I push on the MEDM screen, the preamp does not seem to respond. The Overload Input and Output status lights (right hand side of the front panel) glow red. What's wrong?
A: The Overload light symptom usually indicates that an internally mounted IC needs to be replaced. Take this unit out of service, label it with a description of the problem, and give it to Ali. Make an entry in the beamline trouble log.
Q: Is there a public APS site to which external users can put data?
A: Yes, they can ftp to epics.aps.anl.gov as anonymous and place the files in the incoming directory.
