The RITS accelerator (5–11MV, 100–200kA) at Sandia National Laboratories is being used to evaluate the Self-Magnetic Pinch (SMP) diode as a potential flash x-ray radiography source. This diode consists of a small, hollowed metal cathode and a planar, high atomic mass anode, with a small vacuum gap of approximately one centimeter. The electron beam is focused, due to its self-field, to a few millimeters...
The RITS-6 inductive voltage adder (IVA) accelerator (3.5–8.5 MeV) at Sandia National Laboratories produces highpower (TW) focused electron beams (< 3mm diameter) for flash x-ray radiography applications. The Self-Magnetic Pinch (SMP) diode utilizes a hollowed metal cathode to produce a pinched focus onto a high-Z metal anode converter. There is not a clear understanding as to the effects various...
The results presented here were obtained with an SMP diode mounted at the front high voltage end of the RITS accelerator. RITS is a Self-Magnetically Insulated Transmission Line (MITL) voltage adder that adds the voltage pulses of six 1.3 MV inductively insulated cavities.
The self-magnetic pinch (SMP) diode is an intense radiographic source fielded on the Radiographic Integrated Test Stand (RITS-6) accelerator at Sandia National Laboratories in Albuquerque, NM. The accelerator is an inductive voltage adder (IVA) that can operate from 2–10 MV with currents up to 160 kA (at 7 MV). The SMP diode produces spot sizes as small as 1 mm FWHM depending on the diode configuration...
The RITS-6 accelerator (4–7.5 MeV) at Sandia National Laboratories produces high-power (TW) focused electron beams (< 3mm diameter) for flash x-ray radiography applications.1 The beam is generated in a Self-Magnetic Pinch (SMP) diode, which utilizes a hollowed metal cathode to produce a pinched focus onto a high Z metal converter. Optimum radiographic performance requires a small pinch spot size...
