PREP: Keeping experiments well equipped since 1970

Back in the day, if Fermilab scientists needed equipment for an experiment, they'd go to the Physics Research Equipment Pool. PREP was created more than 40 years ago as the backbone of equipment-sharing for scientists, providing electronics for data acquisition in a long series of experiments at Fermilab.

Today, PREP still plays a strong support role in supplying researchers with equipment they need to successfully test and run experiments. While most of the equipment is used here at Fermilab, many U.S. universities, as well as other U.S. labs and a few foreign institutions, also request items from PREP's stash of goodies.

"When somebody needs to set up a test stand, the first stop is often PREP," said PPD's Jonathan Lewis, acting PREP manager. "While most of our stock is legacy equipment, we still provide equipment crucial to many experiments — crates, amplifiers, logic modules, digitizers and high-voltage supplies."

Remarkably, PREP is free, and it runs on the honor system. The PREP manager approves reasonable requests for equipment use on the Fermilab site. Requests for equipment by outside labs and universities are subject to approval by the Property Office or Fermi Site Office. Once returned, PREP staff test equipment for function and place it in the ready-to-issue area. About seven people maintain PREP. Lewis encourages users to return equipment as soon as they are done with it.

"Popular modules like the LeCroy 222 seem to fly of the shelf as soon as we put them out," he said, referring to a device crucial for timing electronic signals.

The PREP group is remodeling the program with the future in mind.

"We're trying to reorganize to best serve the needs of the neutrino and muon programs, as well as detector R&D," Lewis said. "In the past year we've revamped our procedures, added a full-time repair technician and built a new user-friendly website."

PREP has its sights set on acquiring more up-to-date technology to benefit Fermilab and borrowing universities.

Lewis hopes that PREP's potential new electronics will reflect the technology that scientists are using for these types of programs.

Bob Tschirhart, scientist in the Scientific Computing Division, recently used PREP's equipment for test beams.

"The equipment PREP has is quite useful, but I've been interested in getting more modern equipment in there," he said.

"Our goal is simple," said Lewis. "We aim to back experiments and provide them the electronics support that they need."

Rebooted muon experiment tests detector design at SLAC

From SLAC, Aug. 5, 2014

Last year, a monster magnet set out from Brookhaven National Lab on an epic, 35-day trek by land and sea to its new home at Fermilab, where it will serve as the heart of a search for evidence of new subatomic particles. Last month, with much less fanfare, researchers came to the End Station Test Beam (ESTB) facility at the Department of Energy's SLAC National Accelerator Laboratory to test the eyes and nerves of the same experiment: a cutting-edge design for a new detector.

The goal of the experiment, called Muon g-2 (pronounced gee-minus-two), is to precisely measure a property of muons by studying the way their spins precess, or wobble like a slowing top, in the grip of a powerful magnet. Researchers can track this spin by observing the muon's decay into electrons, their lighter, longer-lived siblings.

CMS excitement

Joe Lykken

When I joined the CMS collaboration seven years ago, I was motivated both by the exciting discovery potential of the Large Hadron Collider and by the fact that many of my friends from the Tevatron experiments were starting to move into leading roles for CMS. In the years leading up to the July 4, 2012, announcement of the Higgs boson discovery, I witnessed from the inside how the momentum carried over from the Tevatron era enabled, on many levels, the remarkable success of the CMS experiment.

But wait — there's more. The LHC will be turning on again early next year with both higher collision energy and higher "luminosity" — the rate at which collisions occur. This raises the prospects for many kinds of discoveries, including new heavy particles (perhaps the "superpartners" predicted by my favorite theory, supersymmetry), or unexpected properties of the Higgs boson. I have placed a friendly bet with Tom LeCompte, the former ATLAS collaboration physics coordinator and our Argonne neighbor, that superpartners will in fact be discovered by CMS and ATLAS during this next LHC run.

Continued success of the CMS experiment requires significant upgrades to the CMS detector to meet the challenges of higher-luminosity running. The U.S. CMS collaboration has taken responsibility for upgrading three major subsystems in a Phase I upgrade project jointly funded by the Department of Energy and the National Science Foundation.

Last week, this U.S. CMS project passed the simultaneous CD-2/CD-3 reviews, allowing these crucial upgrades to proceed. It was all smiles at the closeout last Thursday. This achievement reflects excellent work by the CMS Detector Upgrade Project team led by Steve Nahn, with deputies Aaron Dominguez and Lucas Taylor, involving CMS collaborators from many universities and labs and lots of talented people at Fermilab.

A proud day for U.S. CMS, with many more to come.

Now in Fermilab Library: exhibit on Native Americans on Fermilab site

A small, new exhibit for employees and users is on display in the Fermilab Library on the third floor of Wilson Hall. Titled "Native Americans on the Fermilab Site," the exhibit showcases the work of archaeologist Ann Early and August Mier, a local collector who donated Native American artifacts he found on the land that became the Fermilab site.

View arrowheads left on Fermilab's grounds thousands of years ago and articles published in the 1970s on Early and Mier's work.

View the virtual exhibit for more information.

Emily Loomis of the Information Resources Department designed the exhibit.
