Special Announcement

East gate closed today through Friday

From today through late afternoon on Friday, June 26, Fermilab's east entrance will be closed to allow Canadian National Railway to make repairs to the tracks and crossing in that area. All motor and bicycle traffic that normally enters through that gate will need to enter through the Pine or Wilson street gates on the west side. Check Fermilab Today for updates.


Cervando Castro: Steady hands and sharp eyes

Cervando Castro (left) watches the monitors and operates the remote crane control with technicians John Featherstone and Keith Anderson (center) for the NuMI experiment.

In a few weeks, Cervando Castro will use a remote control crane to change a key piece of equipment in Fermilab's neutrino program. He will be located behind several feet of concrete shielding at distances of up to 100 feet from the component. It's a job where steady hands and sharp eyes are essential.

"Cervando's very focused and very calm in high-pressure situations," said Kris Anderson, lead engineer for NuMI target hall operations. "We rely on him a lot."

As part of regular maintenance, Cervando will swap out the NuMI target, the piece of the experiment that helps to create neutrinos from protons. But, because the target sits directly in the beam path and becomes radioactive, Castro will use several video monitors and a remote crane control from behind shielding to do the job.

"Cervando has a lot of experience in the lab, he's our main crane guy," said Mike Andrews, NuMI shutdown coordinator.

Castro, who has a background in welding and auto mechanics, is the senior technician for the NuMI target hall. He assembles, installs and maintains equipment and parts for the experiment, a job he previously did in the mechanical support department for the Tevatron.

While assembly and maintenance are relativelyf commonplace for the 25-year laboratory veteran, Castro was thrilled about his new challenges and his vertical commute when he started at NuMI.

"The first couple of times I was pretty excited to go down 150 feet into the NuMI target hall," Castro said.

Then, the diversity of tasks Castro's job includes--from assembling very delicate pieces of equipments to moving large chunks of concrete--keep him challenged. The largest piece of equipment he has had to move with the crane weighed 50,000 pounds. His schedule keeps him busy too. As a NuMI technician, Castro has to make himself available day or night as his job requires.

"I'm willing to do that because I want help make this place run smoothly," Castro said.

CERN reports on progress towards LHC restart

From Interactions.org, June 19, 2009

At the 151st session of the CERN Council today, CERN Director General Rolf Heuer confirmed that the Large Hadron Collider (LHC) remains on schedule for a restart this autumn, albeit about 2-3 weeks later than originally foreseen. Following the incident of 19 September 2008 that brought the LHC to a standstill, a great deal of work has been done to understand the causes of the incident and ensure that a similar incident cannot happen again.

"Many new tests have been developed," said CERN's Director for accelerators, Steve Myers. "That's given us a wealth of information about the LHC splices, and confidence that we will be in good shape for running this year."

The root cause of the September incident was a faulty splice in the high-current superconducting cable between two magnets in LHC sector 3-4. New non-invasive techniques have been developed to investigate the splices, of which there are some 10,000 around the LHC ring, and determine whether they are safe for running or whether they need to be repaired. As part of this process, one more sector of the LHC, sector 4-5, is currently being warmed up. This will bring increased confidence that the splices are fully understood.

Shutdowns are busy times

Ron Moore
Ron Moore, a blogger for Quantum Diaries.

On Monday, we began a 3-month planned shutdown of the accelerators for maintenance, upgrades and a little construction for future operation. Although we may not be delivering beam to the experiments, there is plenty of activity going on around the Fermilab accelerator complex. The Accelerator Division "borrows" technicians from all over the lab to get all the work done.

For the Tevatron, maintenance is the biggest task. It has been 20 months since the last long shutdown ended and many items have accumulated on the to-do list.

ES&H Tips of the Week - Cyber security health

Passwords: Longer is stronger

Lock up your information with a strong password.

Have you ever wondered how easy it is to crack a password, and how it's done? Attack methods for cracking passwords include simple techniques such as guessing, especially if the attacker knows something about you such as your birthday or your dog's name. So don't base your passwords on information someone might easily know about you. A slightly more sophisticated method is called a "dictionary attack." This method uses words straight out of the dictionary to see if they work as your password.

A "brute force" attack relies on trying every possible combination of characters, and in theory will always be successful given enough time. But if you choose a long enough password, the time required to run all the possible combinations becomes so long that it is not practical. "Rainbow tables," available in the hacking community, are a compilation of all the encrypted forms of passwords, so that it's only necessary to look up the original password once the encrypted form of the password is known. Simple four- or five-character passwords can be cracked in the few seconds it takes to return a result from the lookup. This technique also gets more difficult as the password length increases--another good reason to use a long password.

A recent Fermilab cybersecurity audit called out several applications at the lab that aren't enforcing password complexity that complies with current DOE requirements. Part of the Tune IT Up campaign calls for enforcing the required password complexity. Over the next months, the laboratory's central computing systems will begin enforcing more stringent password complexity requirements. To make that transition easier you can begin using more complex passwords:

  1. Use at least 10 characters
  2. Include letters, numbers and at least one special character (the # sign, for example)
  3. Don't use a number for the first or last character.
