Hadron Collider School engages new generation of particle physicists

Starting this past Monday, the seventh annual Joint Fermilab-CERN Hadron Collider Physics School opened Fermilab’s doors to 123 doctoral students and postdocs in high-energy physics for a two-week series of lectures in the field of collider physics.

Most of the students work on either Tevatron or Large Hadron Collider projects, said DZero co-spokesperson and event co-chair Dmitri Denisov. The purpose of the school is to broaden students' knowledge of collider physics, introduce the students to experts in the field and help them develop contacts they can maintain for their entire professional lives.

“At this school, all students, from across borders, come into the same room to learn what they are concerned about, what ideas are floating around,” Denisov said. “It’s very productive.”

Students in the Fermilab-CERN Collider School are encouraged to reach out to their classmates in a variety of social events, including a day exploring Chicago.

But it’s not without hard work. Students learn from fifteen prominent scientists engaged in research at Fermilab and CERN. The instructors deliver lectures on various topics in collider physics with a focus on the importance of the students’ future work in the field. Fermilab physicist and event co-chair Patrick Fox added that the school will cover as many aspects of collider physics as possible.

Students were excited to be at Fermilab and to have an opportunity to meet others. University of Hamburg graduate student Henning Kirschenmann, who works on the CMS experiment at the LHC, said it was good to see people outside his collaboration.

“I’m looking forward to getting to know colleagues across the boundaries of our experiments,” he said.

Denisov said the school also mirrors Fermilab’s status as an international laboratory, with the students coming from over a dozen countries.

Regardless of their point of origin, Denisov said, the students have an opportunity before them unlike any other.

Fox agreed.

“The students here have the opportunity to meet counterparts from different experiments from different countries,” Fox said. “It’s great that Fermilab decided to host this school, and we will do our best to make it a success.”

The school runs from Aug. 6 to 17, with lectures in One West.

After particle search, some wallets may lose mass

From The New York Times, August 6, 2012

When physicists at CERN reported on July 4 that they had discovered a new particle resembling the long-sought Higgs boson, it prompted a worldwide celebration of pride and mystification.

It also prompted a worldwide settling of scores as physicists — inveterate gamblers — examine the data to decide whether it is time to pay up on longstanding bets about the existence of the boson, which has been the object of a 40-year manhunt.

How ALARA minimizes radiological exposure

John Anderson Jr., AD ES&H Department Head and Senior Safety Officer, wrote this column.

John Anderson Jr.

The work taking place during the 2012 shutdown marks the next phase of Fermilab's migration to research at the Intensity Frontier. In the Accelerator Division, we are working on upgrades to the Linac, Booster, Recycler, Main Injector and the NuMI areas in support of the laboratory's experimental program.

Although we're three months into the shutdown, the planning for our shutdown activities began years ago. This includes creating an ALARA plan to minimize the radiological exposure workers are anticipated to receive in the accelerator tunnels while completing the upgrade activities.

So what is ALARA?

ALARA is the acronym for As Low As Reasonably Achievable. At Fermilab, this means making every reasonable effort to keep radiological exposures to personnel as far below established dose limits as practical, taking technological and economic aspects into consideration. The Fermilab Radiological Control Manual specifies a dose limit of 1,500 millirem per year, lower than the federal standard of 5,000 millirem per year we are required to meet. For comparison, according to the Health Physics Society, the dose from a typical chest CT (computed tomography) scan is 700 millirem.

ALARA planning includes examining the work activities performed in radiological areas and estimating the dose to workers. The AD Radiation Safety Group creates an ALARA plan by breaking down each shutdown task into its most basic steps. For each step, our group works with the project engineer or manager to estimate the number of people needed and the time required to complete the step. Oftentimes, these teams devise more efficient ways of performing the work to reduce the amount of time people will have to spend in the accelerator tunnels. Next, the Radiation Safety Group estimates the radiation dose rates where the work is to be performed. The estimated dose a worker assigned to a particular step will receive is the product of the estimated dose rate where the work is to be performed and the estimated time it takes to perform the work. The Radiation Safety Group then adds up and evaluates the estimated dose for each step to provide an estimate of the total radiological exposure to workers from the task.

Once this phase of the ALARA plan is complete, we optimize the work schedule and the activities in the tunnels while keeping doses to workers as low as reasonably achievable. Typical ways to reduce exposure include delaying work activities until dose rates in the accelerator tunnels have decreased, changing the way work is performed, limiting the amount of time a worker can spend on a task and using temporary shielding to reduce dose rates.

We require all workers who enter the accelerator tunnels to wear both a pocket dosimeter and a dosimetry badge. The pocket dosimeter allows us to estimate the radiological exposure in real time. The dosimetry badge allows us to monitor the actual radiation exposure of each worker.

The ALARA philosophy balances the laboratory's programmatic needs with the radiological safety of its workers. ALARA plans help ensure that the laboratory's work is being performed in both dose- and cost-effective manners.

Implementing ALARA planning for shutdown activities is one of the many ways the laboratory keeps its workers safe. If you have questions about radiation safety, please contact your D/S/C Radiation Safety Officer.

Safety Update

ES&H weekly report, Aug. 7

This week's safety report, compiled by the Fermilab ES&H section, contains four incidents.

A contract employee suffered a hernia while pulling cables. Medical treatment plus days away from work make this case a DART.

An employee suffered a minor injury to her eye when she poked it with a file folder. She received first-aid treatment.

An employee was stung by a wasp and received first-aid treatment.

An employee reported that he removed a tick that was crawling on his leg.
