Abstract :
The MIT-Bates SHR, a 190 m long race track shaped electron storage ring with a 9.144 m bending radius, is designed for nuclear physics experiments using two modes; the STORAGE mode with internal targets or the PULSE STRETCHER mode, which uses the 1/2 integer resonance and 2 ramped quadrupole magnets and 3 octupole magnets to (smoothly) extract the stored electrons of up to 1.0 GeV energy and 80 mA intensity over a period as short as 1 millisecond into the extraction line
