Overview


Hall D is a new experimental hall

to be located on the east side of the
north linac


Construction costs for the tunnel and experimental area is the civil
estimate


Delivery of the electron beam is the responsibility of Accelerator


The design, construction and commissioning of the photon beam
and experimental equipment is the responsibility of Hall D/GlueX


The
GlueX physics collaboration

(approximately 70 people from 25
institutions) has been together for six years


Provides scientific motivation for mapping the spectrum of gluonic
excitations


Working on R&D projects relevant to the detector design


Taking advantage of existing hardware


Solenoid magnet used for the LASS experiment at SLAC and the MEGA
experiment at LANL


Lead glass used in BNL E852

Physics goals and key features

Normal mesons:

glue is
passive

Hybrid mesons:

glue is
excited

q
q
q
q
The physics goal of GlueX is to map the spectrum of
hybrid mesons starting with those with the unique
signature of exotic J
PC
.

Identifying J
PC

requires an amplitude analysis which
in turn requires



linearly polarized photons



detector with excellent acceptance and resolution



sensitivity to a wide variety of decay modes which
include photons and charged particles

This, coupled with a hybrid mass reach up to
2.5 GeV, requires
9 GeV photons

produced using
coherent bremsstrahlung from
12 GeV electrons
.

R&D


Barrel calorimeter
: to study light collection and readout of
barrel calorimeter in the magnetic field; test fibers to
optimize performance and minimize cost


Flash ADC
: to develop high

Contingency Summary


Major cost items


Barrel calorimeter (Detectors)


FADCs (Electronics)


Contingency is in line with overall project. It is an average of elements that are
fairly well known and others that still in the conceptual stage


Contingency on infrastructure is appropriate for this stage of the project, given
that a detailed installation plan and schedule are yet to be developed

Hall D Conclusions


Physics program has driven the choice of experimental
equipment


technical scope is well
-
matched to the performance goals


Cost have been reduced by reusing
existing pieces of
experimental equipment

(solenoid and lead glass)


Reviews of the detector

design parameters have helped
establish the technical, cost and schedule scope


low technical risk


definition of R&D program to address cost and schedule
risks


reliable estimates of contingency for this stage of the project


Planning is sound

and based on six years of intensive
preparations by the GlueX collaboration
