**INTRODUCTION**

This is a memorandum of understanding between the Fermi National
Accelerator Laboratory and experimenters from Georgia Institute of
Technology and the University of Kentucky who have committed to
participate in beam tests to be carried out during the 2006-2007 MTBF
program. The memorandum is intended solely for the purpose of providing
a budget estimate and a work allocation for Fermilab, the funding
agencies and the participating institutions. It reflects an arrangement
that currently is satisfactory to the parties; however, it is recognized
and anticipated that changing circumstances of the evolving research
program will necessitate revisions. The parties agree to negotiate
amendments to this memorandum which will reflect such required
adjustments.

The tests involve determination of the shielding effectiveness of boron
nanoparticle and microparticle shielding materials. This work is being
funded by NASA and in a joint partnership between the University of
Kentucky and Georgia Institute of Technology. Polyethylene based boron
nanoparticle and microparticle shielding materials have been fabricated
by the University of Kentucky, Materials Science division. These
materials are to be experimentally tested in a high energy particle
beam. The tests will start late in the calendar year 2006. These tests
will be used in part to finalize the shielding effectiveness tests of
this novel shielding material.

# **II. EXPERIMENTAL AREA, BEAMS AND SCHEDULE CONSIDERATIONS**

1.  LOCATION

    1.  The experiment is to take place in the Meson beam lines, in an
        area that can receive high intensity protons. The experimenters
        need approximately 1 cubic meter and will provide all necessary
        positioning equipment. In addition, the experimenters require a
        location to set up data acquisition equipment that can be manned
        continuously.

    2.  The experimenters will need a 1 cubic meter area inside the beam
        line for electronics and will utilize patch panels available or
        provide adequate test leads for the electronics needed. Most of
        the data acquisition electronics will be housed in the control
        space and utilize a NIM bin as well as several laptops.

    3.  Additional work space will be needed in the control space,
        equivalent to at most two 6'x3' tables. This space will be used
        for computing and general work space.

2.  BEAM

    1.  BEAM TYPES: The tests will use slow resonantly-extracted, Main
        Injector proton beam focused onto the test apparatus. The test
        requires a beam of charged protons at a maximum energy of 120
        GeV. The test requires as large a beam spot as can be made, up
        to approximately a 6 cm x 6 cm. Lower energy beams for
        comparison studies are helpful to this program of measurements.

    2.  BEAM EXTRACTION: We expect to run in the SY120 extraction mode
        where beam is delivered during a 12 hour period during the day.

    3.  BEAM INTENSITY: High intensity is a necessity in this
        experiment. Fluxes on the order of 7 x 10^10^ protons per
        measurement point or greater are needed. Approximately 200-300
        measurement points are envisioned.

    4.  BEAM SHARING: If the measurement takes place in another beamline
        other than MTest, then beam can be split to that facility as
        well, as long as the flux indicated above is received.

    5.  RUNNING TIME: Beam time needed will be approximately 5 days.
        Several days of this will be setup time.

> 2.3 SETUP
>
> 2.3.1 The experimental setup will consist of an acrylic tank filled
> with tissue equivalent liquid or deionized water. In addition to the
> tank, an X-Y positioning table will be used to move a Tissue
> Equivalent Proportional Counter (TEPC) through the water block, as
> well as the material to be tested. The material to be tested will
> consist of contained ground polyethylene, ground polyethylene with 5
> weight percent boron nitride microparticles, polyethylene with 5
> weight percent boron nitride nanoparticles, polyethylene with 5 weight
> percent boron carbide microparticles, and known calibration
> thicknesses of aluminum metal. These particles are molded into solid
> blocks approximately 7x5x0.5 cm\^3 and these blocks will be stacked in
> various configurations. These components will be shipped to the users
> and carried on site by hand.
>
> 2.3.2 A table or similar object is required in the beamline to support
> the acrylic tank and X-Y positioner, and a location for the materials
> to be tested. The beam can be located 9 inches or more above the table
> or support surface. We expect to have less than 300 pounds of material
> in less than 1 meter length.
>
> 2.3.3 Electric power for electronics both in the beam area and in the
> counting house is required.
>
> 2.3.4 The experimenters will utilize a very small quantity of methane
> based TE gas. The flow rate will be 6 cubic centimeters per minute at
> pressures of 1 psi above atmospheric. This flow will be shut off when
> the detector is not in use to limit the amount of gas released. This
> flow rate poses no threat of creating a flammable gas atmosphere or an
> oxygen deficient atmosphere. A lecture bottle will be used to contain
> the gas. If necessary a vent line can be established. The bottle will
> be secured in an appropriate fashion at all times.
>
> 2.3.5 An ethernet connection is required for data transmission offsite
> from a computer which will use ssh to transfer files to and from
> computers located at Georgia Tech. If there is a firewall issue, the
> data can be transferred in sequential transfers between networks.
>
> 2.3.6 Access is required to the beam area periodically for
> installation and cabling and switching the materials to be tested. It
> is expected that AD and PPD will help coordinate this access.
>
> 2.3.7 Georgia Tech will supply at least one DAQ computer.
>
> 2.3.8 We will need assistance on how to use the accelerator beam
> readouts.
>
> 2.3.9 We require a record of accelerator information on beam intensity
> for each spill of beam on our detector.
>
> 2.4 SCHEDULE
>
> 2.4.1 The experimenters plan to do this test in calander year 2006,
> with the exact schedule depending on beam availability. We require
> several hours at a low beam rate to look at signals on the scope and
> make suitable adjustments to electronics and the data-taking program.
> When everything is working properly, approximately 40 hours of beam at
> 7E10 protons/minute will provide ample data.

6.1 The responsibilities of the Microparticle Shielding Spokesperson and
procedures to be followed by experimenters are found in the Fermilab
publication \"Procedures for Experimenters\" (PFX)
(<http://www.fnal.gov/directorate/documents/>). The Physicist in charge
agrees to those responsibilities and to follow the described procedures.

6.2 To carry out the experiment a number of Environmental, Safety and
Health (ES&H) reviews are necessary. This includes creating an
Operational Readiness Clearance document in conjunction with the
standing Particle Physics Division committee. The Microparticle
Shielding research group Spokesperson will follow those procedures in a
timely manner, as well as any other requirements put forth by the
division's safety officer.

6.3 The Microparticle Shielding Spokesperson will ensure that at least
two people are present at the Meson Test Beam Facility whenever beam is
delivered and that these people are knowledgeable about the experiment's
hazards.
