The Proposed Ion Beam Laboratory at Sandia National Labs^*

A new accelerator laboratory called the Ion Beam Laboratory or IBL has been proposed to the National Nuclear Security Agency (NNSA).  The facility will replace the current lab that is located in a 52 year old “temporary building”.  Most of the accelerator systems will be relocated to the new building, one will be replaced with new accelerators, and an additional accelerator system will be added.  The building is to include all the offices for the IBL staff and is expected to be ~26,000 square feet.  The systems that will be housed in this new facility will include: 1) the existing tandem lab (4 negative ion sources, 6.5 MV Tandem-Pelletron, 1.9 MeV/amu RFQ booster, 3 switching magnets, and 10 beamline/endstations); the existing implant lab (400 kV HVEE implanter with switching magnet and two beamline/endstations);  the Van de Graaff Lab (the 2.5 MV VdG will be replaced, but the magnet and 6 beamline/endstations moved); and a new 100 kV nanobeam will be purchased and installed).   Other additions will include a new microbeam system for the replacement VdG.  A conceptual design of the new IBL will be presented that includes the proposed placement of all these accelerator systems including radiation shielding.  Suggestions for improvements from the SNEAP participants will be welcome.   There may also be opportunities for members of the SNEAP community to help us plan and carry out the daunting task of disassembling, moving, reassembling, and commissioning all of the accelerators, beamlines and endstations.  In this regard, people with considerable experience with this should seek me out during the meeting.
