1
Demonstrating the EM slingshot -The
next step in target injection/engagement-
Graham Flint, Bertie Robson HAPL Project
Review PPPL, Princeton, NJ December 12-13, 2006
2
Must convince a non-technical audience that IFE
target engagement can be done

• Low-mass target (in vacuum)
• Traveling at 50 meter/second
• From gt 10 meter standoff
• With lt 20 micrometer accuracy

3
Integrate target tracking, beam steering and
engagement verification

• To convince a technical audience i.e. ourselves.

4
Demonstrate single-shot engagement with a
fast-moving, low-mass target

• Room-temperature copper drive coil
• 30-80 kJ electrolytic capacitor bank (450-volt)
• Solid-state switching
• 40-50 m/s launch velocity
• Lateral sabot capture to provide clear
  line-of-sight for tracking

5
Provide unarguable evidence of engagement success
200 µs 10 mm

• Target velocity
  50 m/s
• Strobe rate
  5,000 /sec
• Q-switched drive beam energy 40 mJ
