I've changed the subject line of this thread to accommodate a new focus - which is towards the design of a specialty reactor to manufacture dense deuterium. This reactor would be designed for a single purpose of UDD formation - and avoids fusion or expansion of the end-product. It makes sense to manufacture UDD for later purposes as an optimized step, instead of trying to do both at the same time.
“Triple coherency” has special theoretical importance and has been mentioned here before - in other contexts (SPP). Its importance relates generally to the Efimov state and Borromean rings, etc. and the surprising amount of extra stability of three interlocking parameters in quantum mechanics. In this context, it would be the overlapping alignment of three distinct input parameters, which become mutually reinforcing. Two out of three is no help. BTW, the Efimov state applies to QM bound states of three bosons which are not normally bound, and is depicted symbolically by Borromean rings. The waves involved do not necessarily take this form (although that is not ruled out). The three inputs for triple coherency are phonons (sound or ultrasound plus blackbody), magnons (magnetic field waves) and photons (optical light from a laser or a coherent LED light source in the IR). Notably, photons, phonons and magnons have all been shown to enter the BEC state at ambient temperature. If condensation, in the sense of boson densification, is the goal and phonons influence photon and magnon coherence in LENR by entanglement ... and we desire to manufacture dense deuterium... then at first it seemed that it might be best to do so in a cold magnetized chamber - such as a separate cryogenic operation. Robin mentioned that a cold reactor might not be necessary. A strong external sound, at a single frequency, introduced to a lattice which is resonant at that frequency, could result in forced phonon oscillation which corresponds to a harmonic of the primary blackbody frequency, so as to overwhelm the smooth blackbody curve with a steep peak. Ultrasound is involved in previous CF but that involves cavitation, which is not part of the present aim (it would destroy the end-product). Plus, although we know the three parameters can form BECs at ambient, it has not been shown to be possible at elevated temperatures. Not only that, but blackbody radiation of hot objects is poised to interfere with achieving phonon resonance past a certain point as it randomizes phonons into a broad emission curve. If phonon resonance is important to achieving triple resonance, then the combination of ultrasound, but in the form of terahertz waves for maintaining an exact temperature makes sense (this can be accomplished by cooling or heating, in addition to so-called “T-waves”). See http://ns.umich.edu/new/releases/22188-new-t-ray-tech-converts-light-to-soun d-for-weapons-detection-medical-imaging The problem is how do we determine magnon and optical frequencies which reinforce, instead of interfere with a blackbody peak that is going to be much stronger than the input. I am assuming that the progression of frequencies, from lower to higher is: Magnon → Phonon→ Photon >From articles like this one in Nature: http://www.nature.com/ncomms/2014/140429/ncomms4787/fig_tab/ncomms4787_F5.ht ml where it looks like phonons and magnons can be aligned at a few terahertz in a magnetic field which can be achieved with strong permanent magnets (about 1 T). This would involve a cryogenic matrix, and even then ultrasound as an external input is hard to couple. Is there a warmer level - say in the range of 10-30 THz where this kind of triple coherency can be optimized? Yes, for years we have talked about SPP in the lowest range of 20-30 THz, which corresponds to an IR wavelength of around 10+ microns and a temperature of 1000C. This is a magic point where it is practical to align phonons and photons at the same frequency - in such a way that each reinforces the other. But this range is not good for permanent magnets, due to their Curie point, which for NIB is much lower. However, it could be possible to insulate the magnets and cool them while letting the reactor stay hot… or else, simply use cryogenic cooling. Maybe we have come full circle back to the original kind of SPP formation using infrared. However, the cold range using external IR from LED makes sense to me, especially if it is discovered that magnons cannot maintain coherence in the higher range of 30 THz. I have found no evidence that they can, but that could be because all this stuff is very new. In the case of Efimov and triple coherency - we need all three parameters to align. Two out of three is no help.
