Answer:
Degenerative accelerator:
The device which is used to study the brain and degenerative diseases like Alzheimers and Parkinson is called degenerative accelerator.
These accelerator have higher specific activity and it is comparable to reactor products.By using these accelerator many radio active nuclides can be produced those can not be produce by neutron reaction.
These generates synchrotron light that can be used for reveal the inorganic and organic structure.
