Subject: How is a neutrino beam generated in a particle accelerator ?

I recently read an article which mentioned in passing that some work at 
one of the particle accelerators involved the use of a neutrino beam. What 
little I know from reading laymans explanations of neutrinos, they are 
very hard to detect, and are massless, or extremely light, and have no 
charge. This was some time ago, and I have not been keeping up with 
current subatomic particle work, so what have I missed ? How is the beam 
generated ?
