===Summary from 10/27/2015 meeting===
 
−
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)
