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


Gamma Spectra Measurements

Dose Rate Measurements

B24 Measurements


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


AB01 Toroids May 15, 2007)


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


Schedule for today

Schedule for today: agreement)

  • 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)
