You have a slight error in your hall D specs: they are talking 5 uA max, not nA like B. 60 KW of beam. Also, the minimum useful energy for hall D is 12 GeV. For the 24 GeV upgrade, they will want 2.5 (~12 GeV), 3.5 (~16), 4.5 (~20) and 5.5 (~24) passes.He also reminded me that the proposed Hall D does not use synchrotron radiation, rather there is a diamond radiator. In any case, the full specifications to date may be found at: http://www.dustbunny.physics.indiana.edu/~dzierba/DRv2/. Good luck. It is not in HTML and is not easy to find your way around the report.
Last issue, I reported some bad news and good news about the Free Electron Laser (FEL) facility. This time, I have great news. We have surpassed a major milestone with the FEL, exceeding a "proof of principal" goal of 1 kW, going all the way up to 1.72 kW continuous light output. The nearest competitor is a Japanese FEL that can run for brief periods up to 100 W. Currently the light is in the infrared region, but hopefully with some money from the Defense Department, we will have a tunable laser from infrared to ultraviolet wavelengths. It is times like these that I am slightly relieved that laser safety does not fall under RadCon support at Jefferson Lab. Most of the press releases may be found at http://www.jlab.org/news/articles/index.html, which give some further detail.
We've recently completed a recharacterization of our new neutron calibration facility. It's a real gem of a facility - our staff has worked diligently to ensure that the range is very reproducible under all exposure conditions. The source and detector positions are fully automated. We have also made measurements and calculations (using MCNP) to estimate the scatter and direct radiation, to ensure that the detector response is as expected, and to increase confidence in our results.
