Optical fibers for light guides

In case fine-mesh phototubes are necessary, Lei had been looking into obtaining some square, 3 mm × 3 mm optical fibers to test as light guides. He has been in contact with St. Gobain[???], but so far has not succeeded in placing an order for such a small quantity.

  • Lei will ask Richard Jones about what he is using for the tagger microscope.
  • Mark will ask around JLab to see if anyone has spare samples or experience ordering suitable fibers.

=SiPM tests

  • FIU has not received the new model of amplifier for the SiPM array. Mark will ask about shipping one to them from JLab.
  • Sascha Somov is ordering some individual 3 mm × 3 mm SiPM's from Hamamatsu to test, some of which will be sent to FIU. Mark will check on the status of that order.

FIU/JLab MOU

The MOU is ready to give to Allison to see if she has comments before passing it through the concurrence chain.
