General ILL Seminar organised by College III

Although the cold source at scattering facilities such as the Institut Laue Langevin have provided the nucleation point for state of the art neutron research, it has become increasingly evident that particular applications such as imaging, radiation damage, particle physics and training in neutron applications can find great benefit from dedicated facilities which optimize for their particular figure of merit.  In this informal seminar I point to some examples where existing examples of this optimization process exist, and then focus on the specific example of particle physics research with ultracold neutrons and ultracold neutron research.  In the past few decades, a quiet revolution (based on ideas and research from the the 1970's and 1980's) in the field has been ongoing, where new, "compact", sources are being developed with higher and higher performance relative to "conventional" cold source production of UCN.  I review some of the most successful methods developed thus far with solid deuterium and liquid He sources, new ideas to increase production, and mention some of the ongoing puzzles in the field.
