A SURVEY FOR MILLISECOND PULSARS

We have searched 960 square degrees of sky for radio pulsars, using th e 305 m telescope at Arecibo, Puerto Rico. The 430 MHz survey reached a limiting sensitivity for slow pulsars of 0.7 mJy using a dual-polari zation, 32 channel filter bank over 8 MHz of bandwidth. We have detect ed one new millisecond pulsar, 11 new slow pulsars, one previously kno wn millisecond pulsar, and eight previously known slow pulsars. The ne w millisecond pulsar, PSR J2033+17, with a period of 5.9 ms, has been found to be in a binary system. The Keplerian circular orbital solutio n has a period of 56.2 days and a semimajor axis of 20.7 lt-s. One of the slow pulsars, PSR J2043+2740, is the second fastest pulsar that is not either recycled or associated with a supernova remnant. It is nea r the Cygnus Loop remnant, but timing measurements imply a pulsar char acteristic age of 1.2 Myr, which makes an association unlikely.
