3. FAR HALL HUTCH DEVELOPMENT (I)
LUSI staff started working almost two years ago on the details of the design of the FEH Hutches 4 & 5
The FEH hutch 4 and 5 layouts were developed and optimized for the operation of the XCS and CXI instruments, as the instrument design was advanced
Hutch 4 and 5 detailed designs ( location, dimensions, utilities,…) support the science mission of each instrument

4. FAR HALL HUTCH DEVELOPMENT (II)
The instrument Physics Requirements were developed with the Instrument Team Leader input
Team Leaders signed the Physics Requirements document
Current instrument layouts were presented for feedback at the October 2008 Team Leader Meetings
XCS and CXI Layouts were subject to a value engineering exercise
Instrument configurations are approved and progressing toward final design
Hutch dimensions are dictated by the physics requirements, the components included in the current instrument scope and future priorities
Hutch 4 has space reserved for small angle scattering equipment
Resolution of small angles require small pixels and long distances
LCLS Hutches typically involve items that are considered “Front End” optics at synchrotrons

5. FAR HALL HUTCH DEVELOPMENT (III)
A generic hutch was proposed for hutch 6, which can accommodate an additional instrument and occupies the remaining available space
Each experimental hutch has a dedicated control room adjacent to the hutch
Space was allocated for a small “common room” (for experimental set-up) which will be shared among the instruments
We still needed space for the infrastructure supporting the operation of the FEH near the instruments ( PPS racks, mechanical equipment, air handling units, transformers, network hardware, experiment support, equipment storage,…)
This led to plan for a mezzanine above the FEH hutches
Mezzanine structure also provides an exoskeleton which allows for future re-configuration of hutch walls
All walls are non-structural
