      • Organization: I have changed names of files. Also, I have deleted the .pdf file of the document. There are pros and cons to this. Pro: You can take a look at the .pdf directly from the repository. Con: It seems like there are always conflicts generated by the .pdf because of non-essential differences between local versions and those in the repository, which is annoying. Anyway, for now the .pdf is not checked in, but can be added easily if we want to do this.
      • authors: JLab: I think we should add Fernando, Nick and Chris for all the work on Bcal electronics and maintenance. Tim for coordinating all the mechanical issues. USM: They played a substantial role in qualifying the MPPCs, fabricating the light guides, and electronic design and software development for the LED pulsing system.
      • Introductory material: I have moved various material around and modified the section names: Project Background and Detector Requirements / Overview and Design. Some of the details of the description that was in the introduction has been moved to appropriate specific sections, e.g. the SiPM section.
      • Edits (minor): Fibers and Matrix construction
      • Added: Sections on Light Collection / Photo Sensors / Electronics (new). These combine material from 'segmentation' and 2012 beamtest.
      • BCAL_nim.bib file: Modified with additional references, but clearly these will need to be worked on systematically once most of the document is available.
      • I might have too much material in these new sections and they will likely be culled. So far the goal has not been to produce final text, but just gather info and see how the whole fits together.
      • General: Overall, these sections have mostly text and only a few figures ("a figure is worth a thousand words"). This may be ok, since they often refer to other documents, but we can revisit this once most of the sections are filled in.
