The LLNL HEP group has a long history running fixed target hadronic
physics experiments at the BNL and FNAL. Fixed target configurations are
often more able to provide complete coverage and and particle identification.
Past experiments include FNAL E690 to study diffractive charm in p-p collisions
and BNL E910 to study strange particle production proton nucleus collisions.

These full acceptance, high rate experiments often address a wide variety
of physics topics in hadronic physics. For example, E690 has recently
published on lambda polarization, and E910 has published measured a number
of signatures relevant to heavy-ion physics as well as providing data
of value to muon-collider R&D and proton radiography. Also, these experiments
are not above scrounging equipment. E910 made use of the EOS TPC and the
E690 Cerenkov detector.

Currently, we have reassembled the EOS TPC and Cerenkov detector at FNAL
for E907, which will measure particle production for pion, kaons, and
protons incident on targets ranging from H to Pb over and energy range
form 5 to 100 GeV/c. The experiment will address a variety of topics,
including measurements important to Proton Radiography MINOS and the
Relativistic Heavy-Ion Program. Consequently, a substantial number of
the LLNL HEP group members are collaborators on E907.
