ABSTRACT
We wish to search for new neutral particles by investigating the
composition of a wide angle neutral beam produced by high energy protons
on a Be target. Photons in the beam will be removed by a Pb converter.
The resultant neutral beam will be incident on the 30" bubble chamber.
The composition of the beam will be determined from the kinematic analysis
of selected interactions in the bubble chamber, through the decays of
neutral particles and through possible anomalies in the hydrogen inter-
actions. As a byproduct we will measure the K[ flux through the process
KL + P + KS + all. By a slight change in the geometry we can look at a
region immediately downstream of the target and measure the characteristics
of neutral particles arising from the decay of hyperons and other particles
produced in the Be target. We do not require any external equipment besides
beam monitoring equipment. We request an initial exposure of 20,000 pictures.
