2013 Healthcare Reimbursement Account substantiation request

Did you receive a Healthcare Reimbursement Account substantiation request from PayFlex? On April 18, 2013, PayFlex mailed out quarterly substantiation request letters. If you signed up for e-mail notification, you likely received the letter electronically. The IRS requires PayFlex to verify that all PayFlex Card transactions are eligible expenses. PayFlex automatically verifies some eligible expenses because Fermilab communicated to PayFlex the co-pay and deductible amounts. Also, some merchants participate in an inventory information approval system that allows the merchant to automatically indicate if the expense is eligible. You may notice this information on a pharmacy receipt.

If you receive a Request for Documentation or substantiation letter from PayFlex, you must provide documentation for the transactions listed in the letter. The following are a few common scenarios in which substantiation may be required:

  • You used your card at a merchant without an inventory information approval system.
  • The amount of the expense does not match your co-pay.
  • The merchant description from the card swipe does not clarify the type of expense. This generally occurs with dental or hospital expenses.

The most efficient way to respond is via You can upload an Explanation of Benefits or itemized receipt for the transaction(s) listed on or the Request for Documentation letter. To log in, use your Fermilab ID (no leading zero and no "N") and Fermilab's group number of 121378.

For further assistance with FSA substantiation requests, review this FSA presentation.

Remember, if you do not respond to the initial request within 28 days, a second letter will be sent out. If you do not respond to the second request letter, your PayFlex FSA debit card will be turned off.

1973, with the 30-inch bubble chamber experiment


Five faculty, two postdocs, three graduate students

ISU has collaborated at Fermilab on E615 since 1980, on DZero since 1995 (with six Ph.D. students), and on the 4th concept detector and DREAM (dual-readout) for engineering studies and technical work since 2006.

Nowadays, the ISU neutrino group has a strong experimental program collaborating with Fermilab at the Intensity Frontier. We are leading the effort on the first electron neutrino appearance analysis in NOvA. The neutrino group has played a major role in the computing and offline software efforts (infrastructure, simulations and reconstruction) for the NOvA experiment. In addition, the group is working on alignment studies and calibration design for this experiment. In MINOS we played a leading role in the first electron appearance analysis analysis.

In collaboration with Argonne National Laboratory, we are also studying the possibility of using new large-area picosecond photodetectors based on microchannel plates in the new large water Cherenkov detectors being proposed for the next generation of long baseline neutrino experiments.

Icy experiment catches record-energy neutrinos

Scientists on a South-Pole-based neutrino experiment reported today that they have detected the two highest-energy neutrinos ever observed.

These particles stomped the competition, coming in with about 10 times the energy of the previous record-holder. Catching them could be an important step toward solving one of the greatest mysteries of modern astrophysics: Where do ultra-high-energy cosmic rays come from?

Physicists: U.S. needs its own atom smashers

From Live Science, April 16, 2013

DENVER—The United States remains an intellectual center for scientific thought, but is on the brink of falling behind in attracting the brightest minds, physicists said Monday (April 15).

Speaking at the April meeting of the American Physical Society, researchers warned that the United States should commit to funding big science (and big science infrastructure) to remain competitive.

"Only perfect practice makes perfect:" Breaking the 11-Tesla barrier

Giorgio Apollinari

Giorgio Apollinari, head of the Technical Division, wrote this column.

We all know the saying that practice makes perfect. But it is worth remembering that the famous coach of a football team located north of Chicago Bears territory pointed out that "only perfect practice makes perfect"—the mere repetition of activities is not a sure way to achieve perfection. Vince Lombardi understood that in practice itself there is a constant need to focus, improve and advance.

Lombardi's insight applies to the development of new technologies for future accelerators. It is especially true when it comes to the development of magnet prototypes.

Less than one year ago, in July 2012, I reported that a 2-meter-long collared dipole magnet prototype—with accelerator-quality features, made of Nb3Sn and built at Fermilab—achieved a magnetic field of 10.4 Tesla, close to our goal of producing an 11-Tesla magnet. That was a major achievement. But we soon discovered that the magnet's performance was limited due to the damage its superconducting cable must have suffered during the reaction process that created the magnet's superconducting material. (Nb3Sn is a brittle conductor that is very susceptible to mechanical damage during the reaction process.)

In less than six months, we built a new 1-meter-long prototype and began testing it at the beginning of 2013. Building a new prototype magnet was more than good practice. Following Lombardi's advice, we used this opportunity to implement innovations introduced by our magnet scientists. The new prototype features a cored superconducting cable to reduce parasitic eddy currents that can limit a magnet's performance. We also used the new prototype magnet to test an advanced Nb3Sn strand design, which is a promising design for the future production of quadrupole magnets for the LHC luminosity upgrade.

On March 7, our prototype magnet reached a current of 12.54 kiloamps with a calculated field of 11.5 Tesla, thus surpassing the 11-Tesla goal we had set. (As I explained in my previous column, the development of these magnets is part of our general R&D efforts to develop stronger magnets with realistic accelerator qualities for future machines such as a Muon Collider or a Very Large Hadron Collider. The use of such magnets in the foreseen LHC luminosity upgrades is an intermediate step.)

I would like to stress the short time it took us to make and test a new prototype and achieve very good results. It shows the maturity of this magnet technology. An easy extrapolation of our latest results tells us that this magnet technology would allow us to build a Muon Collider with a diameter of approximately 5 kilometers that would fit completely on Fermilab site and achieve center-of-mass collision energies of approximately 10 TeV.

The worldwide high-energy physics community is now involved in a process that I, only half-jokingly, call "generational facilities planning," in the sense that we are planning for facilities that will be exploited mainly by future generations. I am hopeful that further progress in superconducting materials and magnets development will allow us to plan hadron colliders that could exceed 100 TeV center-of-mass energies, about eight times more than the design energy of the Large Hadron Collider at CERN.

Preparing for slipstacking

Last week the Accelerator Division installed this 53-MHz Recycler radio-frequency cavity in the Main Injector tunnel under the MI60 service building. Two of these cavities are required to manipulate the protons in the Recycler through a process called slipstacking. Slipstacking in the Recycler allows for as many as 50 trillion 120-GeV protons, at a rate of one pulse every 1.33 seconds, onto the target for NOvA neutrino beam production.

Safety Update

ESH&Q weekly report,
April 23

This week's safety report, compiled by the Fermilab ESH&Q section, contains one incident.

In February an employee slipped and fell in the parking lot during a snow and ice event, resulting in first-aid treatment. In the weeks after the slip and fall, he continued to have pain and followed up with his personal physician. X-ray examination indicates he suffered a fracture to his wrist.
