Two University phvsii isls ire conduct

to detect explosives in airport luggage.
The testing involves the use of small
quantities of extremely stable explosives,
such as the plastii explosive (4. on «<un

The Federal Aviation Administration,
which is funding the research of profes
sor* Harlan I-efevre and Jack Overley. has
an explosives expert working \sith the

to handle the explosives while they are on
campus.
The Tugene Police Department's Explo
sives Response Unit was contracted to
transport tin1 explosives to and from the
polit e storage hunker at Short Mountain
landfill in a specially equipped explosives
disposal vohit It* on n daily basis The
explosives will remain police property
when the testing is over
Tint explosive materials are only present
during the day and art* stored in a special
explosive containment box tot aled in the
basement of the Volcanology Building,
where the tests are being conducted.
Act ess to the accelerator lab Is restricted
to authorized personnel at all times, and
the Kugene Fire Marshal's office is inspet t
mg the operation for security and sanity.

"These are extremely stable explosives
which t isn’t Ihi sol off bv electrical fields,
and are designed to be shot at and not
explode." Hicks said, adding that there are
no fuses or detonators present Addition

around the Vnlcanologt Building We
realize that some may Is* concerned about
the testing and we encourage supers isors
to show some latitude in accommodating
those workers. Hu ks said in a news

The neutron beam is one of several
seari h methods the KAA is exploring to
find an alternative to the time consuming
and invasive manual search let hniques
used currently Such searches are net es
sary because plastit explosives do not
show up on X mys or trigger standard met
al detectors
The neutron beam ai ts similarly to X
ravs. producing shadowy images of the
various materials inside luggage, but
unlike an X-rav. the neutron beam may Ik>
able to detect the presence of plantit
explosives
The in < elerator being used is unusual
in that it has been in continuous opera

“I believe that it goes on. and
I believe it affects people and

One of the things that needs
