   We have come up with a sample of six new Galactic supernova remnants
   that we propose to survey with ASCA. The selected remnants all show
   soft X-ray emission according to the ROSAT All Sky Survey. We present
   evidence that our sample includes pulsar-powered synchrotron nebulae,
   young ejecta-dominated remnants, and middle-aged adiabatic phase
   remnants. ASCA's broadband spectral and imaging capabilities will
   enable us to clearly identify the nature of these sources and study
   them in detail.
