You can register your personal cell phone number in JList to receive SWAs, weather advisories, laboratory closing notices and other alerts. Additionally, others at the lab will be able to text you from Jefferson Lab’s web staff-search application. In order to register your cell phone number in JList, send an email to telecom@jlab.org with email subject line "Add personal cell to SWA JList List." In the body of the email, provide your name, cell phone number including area code and the service carrier (Sprint, AT&T, Verizon, etc). Questions may be directed to telecom@jlab.org.</font></div><div style="font-family: Times; font-size: medium;"><font face="times new roman, new york, times, serif"><br></font></div><div style="font-family: Times; font-size: medium;"><font face="times new roman, new york, times, serif"><b>Engineering Seminar: The European Spallation Source and its Safety Protection Systems </b> </font></div><div style="font-family: Times; font-size: medium;"><font face="times new roman, new york, times, serif">The European Spallation Source, located in Lund, Sweden, is currently under construction. It includes a linear accelerator, which will send 2.86 ms-long pulses of 2 GeV protons at 14 Hz to a rotating tungsten target with an average power of 5 MW. This spallation source distributes thermal and cold neutrons to a variety of state-of-the-art neutron instruments, at which researchers from academiand industry will investigate scientific questions. ESS plans to deliver its first neutrons in 2019 and reach its full design specifications in 2025, with a suite of 22 research instruments. Decommissioning is foreseen to start in 2065. Annika Nordt will give an overview of the design of different protection and safety systems, such as the Machine Protection System (MPS), Personnel Safety System (PSS) and the Target Safety System (TSS). A statistical reliability model and the impact of early reliability modeling on the design of safety and mission critical systems will be discussed. The presentation will be held in the CEBAF Center auditorium at 1:30 p.m. on Thursday, Aug. 21.</font></div><div style="font-family: Times; font-size: medium;"><font face="times new roman, new york, times, serif"><br></font></div><div style="font-family: Times; font-size: medium;"><font face="times new roman, new york, times, serif"><b>Jefferson Lab Employee Tour Set for Thursday, Aug. 28</b></font></div><div style="font-family: Times; font-size: medium;"><font face="times new roman, new york, times, serif">Have you ever wanted to see the experimental halls and the accelerator tunnel, but have not had the opportunity to do so?
