NPS Crystal Test Planning
Summary from 10/27/2015 meeting
Participants: MAPC, SA, TH, MB, ICP
Measurement of Transmittance using Spectrometer Lambda 750
Transverse Transmittance (stepper motor)
- Testing Subset of Crystals
- Micro-switch to be bypassed for operation with opened door?
- Can anything be damaged if someone opens the machine while operating it?
- Would any accidental light leak be detrimental to the experiment?
- See manual
- Contact company to find out more info (MAPC, Marek)
- Conceptual Test for the stepper motor inside the spectrometer
- Next week: (11/2 – 11/6) - Test with a black cloth.
Longitudinal Transmittance
- Testing Subset of Crystals
- What is the purpose of the windows? Should we remove them?
X-ray Irradiation
- Check with CUA radiation safety before testing machine. (TH, MAPC, ICP)
- Can we move instrument downstairs?
- Clean room in which instrument is located
- Consult manual (MAPC, NP group)
- Check radiation requirements
- Think about measurement of accumulated dose. Is there something in the instrument?
- Search for options of dosimeters (CUA/JLab/internet).
- Check out instrument
- Calibration scheduling (TH, ICP, MAPC).
Additional Points
- Talk with Miguel to inform him of everyone that is working with the spectrometer.
- Build a dark box as a more permanent solution for crystal measurements. (2016, when we have more crystals, NPS group)
To Be Discussed
- NPS frame construction startup (once design drawings ready, est. early 2016)
- NPS magnet construction startup (once design drawings ready, est. early 2016)
