me356's TWO Secrets For Excess Heat Revealed?
According to eye witnesses glow discharge may have been used in Lugano. HT was applied to the mixed fuel before loading into the reactor, OR via a single-wire input to the reactor shortly before the claimed excess heat was produced. [...] It was HVDC and that the aim was to produce a glow discharge, not sparking. Time and intensity not known.
The possible Role of Axions in LENR
There is absolutely zero evidence that Rossi has ever used ultra-pure Hydrogen/Hydrides. Numerous photographs from Bondeno/Ferrara show that he used commercial Hydrogen tanks, and at least while in Italy never synthesized his own Hydrides but used those sold by Alfa-Aesar. He was also very casual about aspects of reactor loading and so on, sometimes starting them up with still damp alumina cement seals. His fuel prep method is still a closely guarded secret - nobody AFAIK - not even people working alongside him know exactly how it is done. But is does involve vaccum and pressurised hydrogen.
MFMP: Automated experiment with Ni-LiAlH
One of the Bologna staff mentioned to me that Rossi would often not wait for the Alumina cement plug in his dog-bones to dry completely before starting a test. He (AR) was of the opinion that water-vapour didn't matter much.

Experimental procedure
======================
https://www.lenr-forum.com/for…t/?postID=44606#post44606
[...] My own work suggests a slower initial ramp - 1C/minute all the way to 725°C, thus allowing more time for a number of complex phase-changes along the way.
me356: Celani Ni Wire replication
I tend to see more 'XSH-like' events at around 700-800C than at 1000C plus- and generally on the way down from 1000 rather than on the way up towards it.
MFMP: Automated experiment with Ni-LiAlH
Anecdotal info from Rossi observers has mentioned the need for a 500C and 700C dwell period.
Reducing Ni Powder and Inspecting It
One of LFH's customers (who must remains anonymous at his own request) Is getting some positive results using a very very slow ramp-up. 1C a minute or so all the way up to 1200C. This customer also does interesting stuff to intensify the field by wrapping an unconnected coil of oxidised wire (non-conducting oxide forms on the surface) around the fuel tube proper

Technical Support - Assembly and Calibration LENR TEST KIT Mk1 'Model T'
[...] I am pretty sure that in order to get his devices not to work [???], Rossi is using square (ish) wave AC at up to 440v input voltage and running at (possibly) 7-800 Hz. Since he uses split phase heaters, there is a powerful 'dynamo' effect on the fuel containment. Attached is a document I wrote some time ago- there is more about the Lugano dynamo effect on page 6.
Negative/Positive Pressures and Plant Schematics - More Evidence We Have Not Seen
No Ultrasound in a Rossi Reactor- but a lot of very turbulent EM fields.
Rossi may have briefly tried US triggering with gas heating - but then went back to EM since it was not reliable. The stethoscope photograph we all love makes me think he can hear the EM from the heaters rattling the fuel containers and can tune the frequency for 'loudest noise'.
I'm pretty sure Rossi's Doral triggering couldn't run at more than 1kHz max, probably 7-800 [Hz].

The heater controls consist of phase-frequency controllers driven by a remote computer using opto-couplers. The opto-couplers are the white squares with a round dot in the middle. The phase controllers are the bigger grey boxes. This system allows the heater current AC frequency to be controlled up to at least 700-800 Hz, maybe a little higher. If the phase controllers were custom-built, maybe they could go to more than that. Also remember that the Cats use 3-phase heating as per Lugano - so the global frequency will be 3X the indicidual phase frequencies - you get what are called 'beat frequencies' or harmonics generated as the phases move in and out of synch. Like the wow-wow-wow you used to hear from old piston engined freight-planes as their props went in and out of synch with each other.
Since 7-800Hz and most of the global harmonics generated are well within the range of normal human hearing, it might well be possible to use a stethoscope to pick up an audible response when you hit resonance - with a colleague adjusting the frequency via the computer. [...]

Strangeness from Lugano
=======================
The Playground
[On Lugano-type reactors] AFAIK btw, all these reactors have a stainless (?) steel tube core. The reactor body was cast around the outside of it in a plastic mould. Unless DW knows better?
[...] Stainless steel oxidation [might be a] problem btw, but I guess Hydrogen inside and potting compound outside protects it somewhat.
Can we talk about Holmlid?
People who have handled 'used' Rossi ceramic reactors (pre-IH) have said that reactors which have run for a long period exhibit a strange 'static charge' phenomenon which persists for long periods (weeks) which is quite inexplicable. The surface when touched has that 'vibrating and slightly crackling' feel you get from being around things like Van der Graaf machines. This buzzy sensation could only be felt on cold and disconnected reactors that had been run on long tests (for unknown values of 'long) and only on those that successfully produced the XSH signal.

[Metallic foil/plate to enhance radiation detection as Holmlid and Russ George suggest] [...] The lead member of the Catalytic Carbon research group I work with has done this independently of Russ [George].

On a more general note I believe that Rossi has experimented with both palladium and copper co-catalysts.

MFMP: Automated experiment with Ni-LiAlH
I attach part of an email received today from Alexander Parkhomov, containing some useful information on his current approach to fuel treatment and 'ignition'. Bob and others may find the content of interest.
Dear Alan,......... I use a nickel powder, made by carbonyl technology with a granule size of a few microns. I do not apply any additional treatment prior to loading into the reactor.
Successful experiments were carried out both with a mixture of nickel with LiAlH4 and with pure nickel saturated with hydrogen gas. Pumping out air with a fore-vacuum pump, filling with hydrogen to a pressure close to atmospheric, holding at a temperature of 200-300 oC for several hours to purify nickel from the oxide, pumping out to remove the formed water, refilling with hydrogen, saturation of nickel with hydrogen at a temperature of 300-400 oC for several hours and after that a smooth increase temperature to 1200-1300 оС. After the release of excess heat, it may be necessary to reduce the power of the electric heating. The pressure in the reactor chamber is kept close to atmospheric pressure........Alexander Parkhomov
