Channeling and some of the things you might do with it at ISABELLE

The phenomenon of channeling of particles through crystals and how it may be used at ISABELLE are discussed. Possible uses of the phenomenon include (1) measurement of beam profiles with a solid state counter attached to the crystal; (2) measurement of energy and intensity of particles--possibility of reduction in relativistic rise shielding (i.e., density effect); (3) providing a variable density target where the density can be varied according to the rotation angle of the crystal; (4) providing a means to do production target experiments where short lived particles produced at one nuclear site can then be targeted onto the following nucleus by aligning the crystal so that the beam is along the channel direction; and (5) providing rapid reduction of beam energy without appreciable loss of intensity
