Abstract:

Not Available Present day pulsed power generators provide such intense sources of bremsstrahlung that may radiation diagnostics are overwhelmed in the near field of the source. Time-integrated radiation-dose maps and spectral measurements are usually made in the near field with TLDs, while time-resolved spectral measurements are typically made in the far field with Si PIN diodes. There is a thus need for compact, time-resolved detectors that can be located in the near field along with a test object to determine the spatial distribution and the bremsstrahlung spectrum on test shots. AASC proposes to develop an instrument to measure the x-ray dose, uniformity and spectrum over a large surface area at the position of a test object in a high dose x-ray simulator with spatial and temporal resolution. In Phase I a prototype instrument will be validated on the MBS simulator at the Arnold Engineering and Development Center. MSB produces a dose of order 1 mca/cm2 with a 30-40 ns pulse-width over an area of 100 cm2. After the Phase I validation, the Phase II goal is to scale the instrument up to measure radiation from the Decade Quad source of about 20 krad (Si), 40-50 ns pulse-width, and 2500 cm2 area.
