Borexino Internal Source Insertion System

This page will house various documents, procedures, photographs, etc. that pertain to the ongoing
design, fabrication, testing, and installation of the internal source insertion system.  This page will obviously
not be updated as regularly as our designs and ideas change, therefore, if you want the most up-to-date
information please email, or call, Bruce, Matt or myself (Steve).

If you are looking for the justification for internal sources, and the insertion system to insert them into the detector, I will refer you to Henning Back's PHD dissertation.  Chapters four and five deal with these issues explicitly.

Below are a few of the many documents produced by VT members throughout the design, testing, and installation of the system.  I will add more of them as they become available. For any additional information, the author(s) are listed for each document, you may find our contact info on the VT Members page. There are many design decisions that have been made in lab notebooks, chalk boards, personal communications, etc., thus making it impossible to document them all here, if you have any questions, please don't hesitate to contact one of us.
