Fermilab's SiDet Facility aides PHENIX detector upgrade

PHENIX, one of two major experiments located at the Relativistic Heavy Ion Collider (RHIC) based at Brookhaven National Laboratory, is upgrading again with help from Fermilab's Slicon Detector Facility (SiDet). Fermilab technicians finished assembling hundreds of forward silicon vertex tracker (FVTX) detector components in early July.

The wedge-shaped components will be installed in PHENIX to help scientists study the properties of quark gluon plasma (QGP), which theorists believe made up the universe moments after the Big Bang.

Eric Mannel, a physicist from Columbia University and one of about 450 PHENIX contributors, worked as an electronics project engineer overseeing the final stages of assembly at Fermilab.

“We want to understand how the universe evolved the way it did from the very beginning,” Mannel said. “The FVTX detector will provide a higher resolution for tracking of particles which will allow us to study the properties of QGP.”

QGP is a near-perfect liquid composed of disassociated quarks and gluons suspended in plasma. It is said to be nearly perfect because it contains almost no internal friction—if you were to stir the plasma, it would continue to swirl forever. Physicists create QGP by smashing heavy ions and protons together. SiDet personnel provided a technical capabilities unique to Fermilab, to construct detectors that will allow physicists to study those collisions in more detail than ever before.

“We anticipate that we’ll be able to reconstruct secondary vertices from the decay of charm and beauty quarks with a resolution of 70 microns. The typical decay lengths for those particles are several hundred microns in heavy-ion collisions at RHIC,” Mannel said. The average human hair is about 100 microns thick.

AAron Veicht, a Ph.D. student at Columbia University, spent nearly 10 months working with the technicians at SiDet and will be part of the team installing the detector in PHENIX this fall.

“I’ll get to see the project from the very early stages all the way through to analyzing the data, so it’s very exciting,” Veicht said.

Special Announcement

Siren maintenance - Aug. 1

The Fermilab sirens will undergo annual maintenance on Monday, Aug. 1. Testing will begin around 9 a.m. Sirens will be serviced one at a time, and the process will take about one hour to complete. Each service will conclude with a brief sounding of the siren. However, if there is the potential for severe weather later in the day, the sirens will not sound during the maintenance service. Please be aware that the normal monthly siren test will still take place on Tuesday, Aug. 2.

In Brief

New Fermilab email project to reduce spam

As part of the email modernization project, the laboratory will switch to a new anti-virus and anti-spam filtering system on Tuesday, Aug. 2.

The new service will dramatically increase the accuracy of identifying and eliminating spam email and significantly decrease the false-positive (valid email identified as spam) rate. The service promises a capture rate of over 99 percent for spam and no more than 0.0003 percent false-positives.

The Computing Sector expects that email users will no longer receive messages that are identified as spam or that contain a virus. However, we encourage you to continue to use caution. Do not open attachments unless you are sure they are safe, and do not automatically assume that an email is from who it appears to be from. In the rare event that either spam is sent to your inbox or that you believe valid email has been identified as spam, you can fill out a form on the spam and anti-virus page linked below that will generate a Service Desk ticket. Email identified as spam will be quarantined and retained for 14 days before it is permanently removed.

Due to the increased accuracy we expect from our anti-virus/anti-spam filtering service, we recommend that you do not use your email client's built-in "This is spam/junk" function to tag or filter email. In the very rare case that you do receive spam, please use the form at the link below to report it, thereby helping improve the filters for everyone.

See the spam and anti-virus page for more information.

Pushing the limits with high-voltage electron guns

From ILC NewsLine July 21, 2011

Jefferson Lab’s electron gun group explores new designs for spin-polarised photoelectron guns.

Opposites attract and like charges repel. This simple phenomenon explains why electron beams spread out over space and time, much to the dismay of physicists who need tight particle beams for collision experiments.

To counter this phenomenon, known as space charge-induced emittance growth, the electron gun group at Jefferson Lab in the US is pushing the limits of high-voltage electron guns with new and improved designs.

This work is motivated and funded by the International Linear Collider R&D programme, the goal of which is to develop a 140-kilovolt (kV) electron gun to produce spin-polarised electron beams.

“The more energy you give the electron beam from the start, the stiffer the beam becomes,” said Matt Poelker, leader of Jefferson Lab’s Electron Gun Group. “The space charge forces that frustrate us get smaller and the beam is much more manageable.”
