  1. T- 489Status Report 4/5/07 Yesterday: • 10am: access to ESA to retrieve Fe • samples and place Ti-alloy samples • Irradiation for 3.5hrs • 2:00 pm: access to ESA to retrieve downstream Fe samples • Continuous gamma spectrometry and dose rate measurements in building 24

  2. Gamma Spectra Measurements Dose Rate Measurements B24 Measurements

  3. Dose rates to be measured over a period of 1000 hours (until May 15, 2007) Short term sample activation levels at ~10 mSv/hr (1mR/hr) on contact Samples Species: Cu, Al, Fe, Ti, TiAlV, SS, dirt, concrete, water B24 Measurements

  4. AB01 Toroids

  5. Check of CID Toroid with respect to CID Faraday Cup (10% agreement) Likely to do a post experiment calibration of AB01 Toro 4140 AB01 Toroids

  6. Schedule for today: • 10am: take out Ti-Alloy and Steel Reference samples put in Al lateral and downstream and Steel Reference samples • Irradiation for 4hrs • 2pm: access to ESA to retrieve Al downstream sample • Continuous gamma spectrometry and dose rate measurements in • building 24 • Will run through weekend until 7:00 AM Monday (09-May-2007)
