Now the major parts of the new calorimetric bench is built and one chamber has been put into a stabilised temperature configuration. A new iteration of the dual differential Celani cells are ready to run again. This time there are a few minor modifications to the cell.
In order to reduce the downtime between two runs, new banana connectors were soldered to the end-leads of each of the cells. Two millimetre diameter banana connectors were used that should take around eight Amps, which is plenty for this experiment.
The heating wires are made of tungsten. Their diameter is 100µm (0.1mm), this was donated by Jean-Paul Biberian from his personal stock. The aim is to enhance monatomic hydrogen generation by heating up the tungsten to large temperature. The effect of this modification on the results is uncertain as the constantan alloy is already supposed to have a catalytic effect on hydrogen dissociation.
The length of the wires inside the cells are shorter than before. This will allow them to be supplied with higher power using the same power supply. The approximate length of the wire is 65cm. As a consequence, the mica supports have been adjusted to enable this modification.
The new calorimetric bench is quite big, so it was necessary to make space in the room for that. So the setup was moved toward the side of the room, where the temperature is expected to be quite stable.
The new constantan wires are both black, in one of the dual cells there are Celani wires which are covered with oxides (CuO). In the other, a BLOCK constantan wire is mounted. This is similar to the original ISOTAN but has a manganese oxide layer on its surface, acting like a protective coating against oxidation.
The protocol has not yet been decided yet, so if you want us to test variations of electrical power cycles or something else, as ever, let us know below.
UPDATE#1 - Calibration done and gamma detector running nicely
The cells have been calibrated and yet another NaI scintillator has been commissioned - but this time it is working very nicely. Expect some examples of its output in the next few days.
So perhaps as early as next week we may finally be able to look to see if there are any gammas released during shock cooling/H2 injections and what energies they are.
UPDATE#2 - 1000+ layer wire in on a live test run
Mathieu has placed an unused but old 1000+ layer wire into the cell to test it and the scintillator.
The 1000+ layer was prepared by Francesco some time ago based on commercially available Block Constantan wire, the control cell has the same Block Constantan wire but without treatment.
