Other projects include the commissioning of four new beamlines in the near future. We are busy with calculations. Outside interests at the university have decided to build a three-story office building within 200 feet of the facility. No one thought to inform the radiation safety staff and we only found out by accident. Initial calculations show line of sight problems from 13 to 50 feet in height for the proposed building. These calculations will be followed up by experimentation. Those of you who are familiar with the CAMD facility might be aware that the storage ring has no radiation cover or roof over the ring. These new changes are troublesome and may represent some serious health physics considerations.
We continue to move towards the installation of PLC's (programmable logic controllers) for our radiation interlock beamline controls. Re-evaluation of hutch thicknesses and construction is also being done at this time. A new NIM (normal -incidence monochromator) beamline design has been approved. The unique structure of this beamline could make the installation (at least in the classical sense) of bremsstrahlung shutters obsolete. So it is calculate, calculate, calculate! - so off to work I go.
