How many Celani wires can we fit in a tube?

It sounds like the start of a joke, doesn't it?

Many times we have thought about trying to amp up the signal to noise on these experiments by testing with more wires.  Good news - it's time, and we need your help to determine the most expedient protocol.  Here is the start we have:

Our Concentric Tube Calorimeter is ready for a new test.  Which wires should we put into this test?

These are the wires we have and what we propose to install.  

-400 layer - 1/2 meter - 40 cm installed

-350 layer - 1 meter    - 40 cm installed

-270 layer - 1 meter    - 40 cm installed

-400 layer - possibly damaged from version 1.3 cell overcurrent

Here is the LENR Stick we are preparing.  Pictures of Multiwire  Cell:

NiCr heating wire wrapped in fiberglass insulation sleeving up and down on the last 7-8 inches (20 cm) of LENR Stick reactor.  Large fiberglass insulation sleeve over the whole end of the LENR Stick reactor.  This will serve to hold the heater in place and to slightly insulate the reactor.

Thermocouple on the outside of the stainless steel reactor is the same spot as the two inside thermocouples.  About 3-4 inches (10 cm) from the end of the reactor.

The whole reactor unit with two pass-throughs and 4 conductors that will allow us to measure the resistance on 3 wires.  Plus it gives us two thermocouples on the inside of the reactor.  

Experiment Open Engagement Plan

Here is our plan to develop this experiment:

- Develop plan to some extent (as we have here)

- post for criticism and suggestions.  The large amount of wire in a small space should be interesting to watch, plus it tests many wires simultaneously and if we see nothing, we move on to another batch of wires.  

- We should discuss the inclusion of acetone later in the test.

- Do we care about resistance drop?  We’ll have the pressure drop. What is P(t0)?  I expect we will charge to several bar and watch it decrease and then replenish, if necessary.

- What else have we had issues with in the past that we will want to prepare for or eliminate this time?

- We have heard that ST Microelectronics heated their wires passively, ramped up in long, small steps, and cycled the several times before seeing excess energy.  Let's try that.

- Having the heater outside the stainless tube should mean that any energy generated inside the tube will create a higher temp inside than outside.

- How are the lengths of wire fit into the cell?  We can sleeve them in fiberglass and we'll need some sort of insulation if we are going to measure the resistance of 3 of them.  Or we have to insert them into ceramic tubes.  Or support them and hold them apart in some other way?

- We have about 20 CM of length available in the tube, so the easiest thing is 40 cm of wire sleeved and folded in half and connected to the copper conductors on each end. Additional unconnected wires can be shoved into the tube in any length, I guess.

Throw out your suggestions into the comments!

Some Experiment Protocol Ideas

- Assemble test cell without active wires

- Use for calibration test of the calorimeter (at the prescribed run pressure of 0.5bar)

- Test for leaks at the same time - during long time at constant power - look for overall stability

- Watch for interior temps vs shell temps

- Take weight, length the wires

- SEM sample of each wire - characterize thickness of shell

- Install all the active wires we can spare.  (Or do we install 40 cm worth so we can do it again?)

- How much vacuum and degassing, if any, do we want?  Look to Celani and ST Microelectronics for guidance - no degassing beyond .5 mBar vacuum, just loading, small 6 hour steps and then cooling off after peak temperature. 

- Pressure for Loading  - will require several cycles maybe 10 cycles- do we want to cool and vacuum between recharging the pressure to purge any H20?  

- Cool down

- Heat and trigger?

- Cool

- Add acetone (make sure design allows for this conveniently)

- heat to same level as previously

- Watch power output levels.

I am starting a formal procedure doc here Protocol:  Multi-Wire Test (read only).  We will update it from the suggestions we get in the comments.  If anyone is super excited to help pull together the suggestions and edit the document, let me know.  Thanks
