The expected shortages of [[Mo-99]], and the [[technetium-99m]] [[medical isotope]] obtained from it, have also shed light onto linear accelerator technology to produce Mo-99 from non-enriched [[Uranium]] through neutron bombardment. This would enable the medical isotope industry to manufacture this crucial isotope by a sub-critical process. The aging facilities, for example the [[Chalk River Laboratories]] in Ontario, Canada, which still now produce most Mo-99 from [[Enriched uranium#Highly enriched uranium (HEU)|highly enriched uranium]] could be replaced by this new process. In this way, the sub-critical loading of soluble [[Uranyl nitrate|uranium salts]] in [[heavy water]] with subsequent photo neutron bombardment and extraction of the target product, Mo-99, will be achieved.<ref>Gahl and Flagg (2009).[http://www.slideshare.net/Flagg707/subcritical-fission-mo99-production Solution Target Radioisotope Generator Technical Review].

*The device length limits the locations where one may be placed.
*A great number of driver devices and their associated power supplies are required, increasing the construction and maintenance expense of this portion.{{r|Pichoff}}
*If the walls of the accelerating cavities are made of normally conducting material and the accelerating fields are large, the wall resistivity converts electric energy into heat quickly. On the other hand,
*[[Superconductivity|superconductorsSuperconductors]] also need constant cooling to keep them below their critical temperature, and thetheir accelerating fields are limited by [[Superconducting magnet#Magnet quench|quenches]]. Therefore
* Due to these limitations, high energy accelerators such as [[SLAC]], still the longest in the world (in its various generations), are run in short pulses, limiting the average current output and forcing the experimental detectors to handle data coming in short bursts.
