| |
| − | Participants: MAPC, SA, TH, MB, ILP
| |
| − | | |
| − | ====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 [http://samba-df.fc.unesp.br/espectrofotometro/manual.pdf Perkin-Elmer L750 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, Miguel P., ILP)
| |
| − | * Can we move instrument downstairs?
| |
| − | * Clean room in which instrument is located
| |
| − | * Consult [http://www.vsl.cua.edu/cua_phy/images/8/8d/CP160_RevB_Combined.pdf CP160 manual] (Miguel P., 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, ILP, Miguel P.).
| |
| − | | |
| − | ====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)
