Advance Registration Open for Users Group Annual Meeting
Many of the procurements for the injector beamline are in progress, and the Innovative Naval Prototype undulator contract has been finalized.
Center for Theoretical and Computational Physics
A two-dimensional coupled-channel scattering lattice model is presented in this latest paper, which describes a two-coupled-channel scalar resonant scattering system. The Monte Carlo simulation is performed on finite lattices and in various moving frames, and the method of extracting the scattering amplitudes from the discrete finite-volume spectrum is discussed. The model sheds light on future coupled-channel hadron-hadron scattering lattice QCD calculations, which will be important for understanding the phenomenology of light hadron spectroscopy from the Jefferson Lab experimental program at 12 GeV.
The Metrology (Alignment group) reports the following activities:

Heat Stress Season Is Coming
Several intersecting factors determine how you will be affected by the heat, including age, weight, level of fitness, medications, diet, alcohol, dehydration and acclimatization (body's internal adjustment to heat). Acclimatization requires about 10 to 14 days in similar heat/humidity conditions. Environmental factors are temperature, humidity, direct sunlight, reflected heat, work load, nearby heat-producing equipment, clothing and PPE.
Jefferson Lab addresses heat stress in ES&H Manual 6670 Appendix T1. Also, the Jefferson Lab weather station, available via a link on the Facilities Management Home Page, continuously displays the Heat Stress Index. Additionally, the weather station triggers pager alerts regarding different heat stress conditions.
For supervisors and SOTRs, never dismiss complaints from an employee/worker who reports not feeling well due to heat and wants to rest in a cooler area. If you observe a worker who seems "out of it," take action to protect him or her. In either case, get the person to Occupational Medicine as soon as possible.

Tracking Thomas at JLab
Samika Hawkins and Brita Hampton correctly guessed the location for May 1. Honorable mentions go to Becky Mosbrucker, DeAnn Maddox, Jodi Patient, Josh Magee, Katherine Myers, Ron Bartek, Dick Owen, Ryan Bodenstein, Marcy Stutzman and Larry Harris. Check out the Tracking Thomas webpage for a better view of his last location and this week's new mystery photo.
