NuMI Achieves Vacuum Milestone

|
On Sunday, May 2, after more than 40 hours of pumping, the NuMI decay pipe
was taken to a full vacuum for the first time, reaching an absolute pressure
of 1 torr (by comparison, atmospheric pressure is 760 torr).
While the level of vacuum is not extreme by particle physics standards, the
2,214 foot long, 78-inch diameter pipe is a key element in creating the
neutrinos that will travel from Fermilab to the Soudan mine. Pions, produced
in the collision of protons with the NuMI target, decay to muons and
neutrinos as they travel its length.
"This 73,500 cubic foot vacuum represents the largest vacuum volume on the
Fermilab site," said Dave Pushka, NuMI project mechanical engineer and
vacuum system manager.
The project, coordinated by Pushka and decay pipe system manager Cat James,
was a concerted effort of lab staff and subcontractors. It began in 1999
when physicists Jim Hylen and Wes Smart performed simulations to determine
the pipe dimensions. In 2000, Edward Chi and Bob Wands of PPD's Mechanical
Department completed engineering calculations and safety notes that were
reviewed by Bill Soyars from AD. Subcontractor Chicago Bridge and Iron,
fabricated the pipe in Texas, then delivered and installed it in 2002.
The pipe's delicate end caps were fabricated and installed by technician
Otto Alvarez and welder Lenny Harbacek. Craig Rogers managed the
installation of the vacuum piping. John Voirin, Tom Rathbun, John Cornele,
and Dwight Featherston installed the pumps and equipment that were critical
to the successful evacuation.

From The Science Coalition, May 10, 2004
TSC Ads Seek to Influence Policy Makers
Promoting research in basic science, six advertisements will appear in The Washington Post in May and early June. Through the combined efforts of Universities Research Association, Inc., Research! America and The Science Coalition, the ads seek to educate policy makers on the importance of funding basic science, even when government resources are scarce.

Electrical Safety Manager Dwight Featherston
Dwight Featherston has worked as Experimental Area Floor Manager
for the PPD Site Department for the last 22 years. His approach
to safety, consistently applied in his years at the laboratory,
|
Dwight Featherston |
has helped prevent any lost-time accidents for the contract
electricians he oversees.
"My safety philosophy is mostly common sense," said Featherston.
"Once you understand your project and break it down, it's easy
to recognize the hazards and what you're going to do to relieve them."
Featherston worked as an IBEW electrician for 26 years before coming
to Fermilab in 1982. At Fermilab, he has managed electrical projects
at PPD sites such as the fixed target area, CDF, DZero, and now MINOS.
Featherston credits the T&M electricians, some of whom have been working
at the laboratory for several years, with helping to assure a safe
working environment.
"It's important to work with the electricians," explained Featherston.
"Most of them are very safety-councious, and if you don't utilize their
talents, you're making a big mistake. One person can't see everything."
