Farewell to DOE's Jim Miller
Jim Miller
Jim Miller
A farewell reception will be held today at 3:00 p.m. on the 2nd floor crossover in Wilson Hall for Jim Miller. After 25 years as deputy manager of the DOE's Fermi Area Office (originally part of the Atomic Energy Commission), Miller retired on January 2. "A piece of me is still with the Tevatron," said Miller, who got involved in the Tevatron project right after coming to Fermilab from Hawaii "just in time for the biggest and hardest winter in Illinois in 78/79." His background in accounting, finance and administration served him well in managing contracts and handling day-to-day business in the DOE office.

Miller and his wife will continue living in the area for some time. However, there's "lots of traveling in our plans," he said. "But I will stay in contact with the lab in some way."

Accelerator Update
January 26 - January 28
- During this period Operations established three stores. Those stores, along with one that already existed, provided approximately twenty-one hours and twenty-five minutes of luminosity to the experiments. The highest peak luminosity was 43.4E30
- A LCW pressure problem caused store to abort.
- TeV wet engine required overhaul.
- To save from quenching, operators aborted store due to Tevatron cryo vacuum problem.

From U.S. Newswire, January 27, 2004
DOE Announces Decision to Compete Management, Operating Contracts for National Laboratories
Pursuant to Section 301(a) of the recently adopted Energy and Water Development Appropriations Act of 2004 (PL 108-137), the U.S. Department of Energy announced today notified U.S. Senate and House Appropriation Committees that it will compete management and operating contracts for the following national laboratories:
-- Ames National Laboratory; Iowa (expiration: Dec., 2004)
-- Argonne National Laboratory; Ill. (expiration: Sept., 2004)
-- Lawrence Berkeley National Laboratory; Calif. (expiration: Jan., 2004)
-- Lawrence Livermore National Laboratory; Calif. (expiration: Sept., 2005)
-- Los Alamos National Lab; N.M. (expiration: Sept., 2005)

Searching for the Big Fat Brother (When He Doesn't Answer the Phone)
DZero Calorimeter
The DZero Liquid Argon Calorimeter (above), and the crew of people who work on it, made this new Z' mass limit possible. (Click on image for larger version.)
Searches for new particles can be conducted in two different ways: either creating them directly or observing the effects due to their exchange in the collisions of other particles. The first approach requires that enough

energy is available to create the new particles. The second approach requires high precision measurements.

Several models predict the existence of a heavier version of the Z boson, dubbed Z'. Measurements of the second type however indicate that this heavier brother of the Z boson couples only with a very small probability

with the Z boson itself. It behaves like a friend who wants to remain hidden and doesn't answer the phone. Asking other friends (particles) for its whereabouts will not lead to his discovery.

Therefore the search for the Z' boson has to be made following the first approach creating Z's. Thanks to the increase in the center of mass energy and in the total integrated luminosity the D0 Collaboration will be able to search for Z' bosons as heavy as 1000 GeV.

With the data collected so far in Run II the D0 Collaboration has extended the region in which the existence of the Z' boson is ruled out by using an analysis similar to the search for extra dimensions. If the Z' is produced and decays in the same way as the standard Z then the old Run I limit of 670 GeV is raised to a limit of 719 GeV.
