Protecting Against Electromagnetic InterferenceBy placing electronics from the retired SLAC Large Detector (SLD) next to a test beam in End Station A, a small group of experimenters is learning how to protect the detector electronics of the proposed International Linear Collider (ILC). Electromagnetic interference is a real concern for the ILC, where very short particle bunches will emit electromagnetic radiation as they travel through beam pipes toward the center of the detector. In the world's first linear collider—the SLC—the detector electronics close to the beam pipe failed, probably due to electromagnetic interference. Physicists worked around the problem by instructing the electronics to wait to read out until after each bunch of particles had passed by. At the ILC, however, the time between particle collisions will be vastly shorter, once every 300 nanoseconds, rather than every eight million nanoseconds. The ILC electronics must read out constantly. Read more... |

Area Hazard AnalysesDo you know about Area Hazard Analyses at SLAC? Known as "AHAs," they are useful informational devices providing scope and details of potential safety hazards in each work area at SLAC. First described in the Hazard Analysis Working Group Report that arose from the lab's Type B Accident, AHAs are required to be produced before work begins in any location. They are then updated at least yearly or more often if safety conditions change in the area. The AHA policy and AHA location library can be found here. Each AHA has at least one person who is appointed by his or her Directorate to produce and maintain it. Each such appointee is known as an 'area responsible person.' Do you know where to find the AHAs for your work areas and who its area responsible person is? The SLAC online library tries to be up-to-date, but you should always seek out the AHA for your work location, familiarize yourself with its content, and identify the area responsible person. Your safety is important to everyone. We encourage you to review routinely your work area AHAs. You should also inform your area responsible person of any safety concerns that you think are not being covered by the AHA so that the concerns can be quickly corrected and the AHA quickly updated as needed. If you have any questions about our AHA policy, please contact Steve Frey, ES&H Assistant Director, at x3839. |
Change in Medical Provider for Work- Related InjuriesSequoia Hospital's Occupational Health Program has closed and will no longer accept new Workers' Compensation injuries. SLAC/Stanford University employees who experience work-related injuries/illnesses will no longer be treated by Sequoia Occupational Health in Palo Alto or Redwood City. Learn more here... Martial Arts for the MindIs stress getting in the way of your work, hurting your productivity, and even causing tension and chronic pain? If so, come to "Martial Arts for the Mind," a training seminar where you will learn to cut down stress, increase concentration, reduce blood pressure, and reduce or eliminate chronic pain. The seminar will be held on Friday, March 23, from 8:30 a.m. until 12:00 p.m. in the Redwood Conference Room. To register, contact Sharon Haynes at x4533. The session will be run by Clarity Seminars. Safety SecondsThe runway numbers that all airports use represent the compass heading of the runway (divided by 10). So, the Kentucky pilots described in yesterday's column should have looked at their compass, seen 220°, and known they were on the wrong runway (they should have been on Runway 26 or 260°). We non-pilots have other safety rules and checks we should be using every day to prevent us from getting injured. |
