At least one pulsar, PSR1257+12 has planets.  Their origin is
 mysterious, but some theories hold that they were formed in
 a debris disk after the supernova explosion.  Such a debris
 disk is expected to be detectable by ISO, and we propose here
 a small survey of young pulsars using CAM.  We have previously
 examined the IRAS data and found 13 pulsars at the positions of
 PSC sources, but this number is consistent with chance coincidence.
 We want now to go 100 times deeper with a small sample of young
 pulsars, imaging in 4 ISOCAM bands to get colors.
