Colleagues,

Construction of a new building to expand our capabilities at the 
LANSCE/WNR Target-4 experimental area has started.  The building doubles 
our capacity for neutron testing of semiconductor devices with the same 
neutron spectrum that presently exists at the ICE House.  The new 
building also provides a special flight path essential for the success 
of neutron output measurements following fission (Chi-Nu). On this 
flight path, a pit in the floor under the detectors reduces the 
background from neutrons scattered from the concrete.

The new building will cover the 15-degree Right and Left flight paths as 
well as parts of the 30-degree Right and Left flight paths, and will 
have a crane to move heavy shielding and equipment.  Contractors are 
presently excavating in preparation for framing and pouring the 
foundation for the building. A detailed schedule is being developed that 
will couple the construction schedule with the installation of the 
flight paths.

We will bring up the Target-4 flight paths in a staged sequential 
manner:  The 90-degree Left (TPC) and the 60-Right (GEANIE) flight paths 
will be the first to receive beam because they are outside of the 
building construction area. The next flight paths to be brought on line 
will be the 30-degree flight paths (Ice House and ICE-II). The last 
flight paths will be the 15-degree Right and 15-degree Left flight paths 
because they require the most installation effort.

We will keep users informed as the work progresses and look forward to 
operations in our new facility.
