In saying that little in the way of prompt charged particles has been observed I am close to parroting the teaching that charged particles are not commensurate with excess heat.

It is well known that the number of fast neutrons or charged > particles emitted from LENR experiments is generally small. [2] So the experiments are challenging and require expensive equipment. The last point about neutrons is easy to agree with; harder so with charged particles. There are people who will argue vociferously that prompt charged particles are not part of the main process or processes in LENR. I suppose there are always a few people who will argue one or another position vociferously. Such people are entitled to their opinion. I myself find this avenue of investigation very interesting. I have many questions: how sure are we about the limits on prompt charged particles? Has an easy generalization been allowed to slip through without a proper investigation? (If so, this would not be the first time.) In those experiments that have been done, in which was there a lot of excess heat? What about the so-called "hamburger" tracks seen in some of the CR-39 experiments? Etc. Eric [1] https://drive.google.com/file/d/0B6id5Hf-xMWOYXVjekJCN1ZkQk0/view, slide 30.
