123		2015-03-02-12:00 UTC	Cell#2: Red channel wire resistance is inconstant probably due to a bad wire connection inside the cell	Nicolas Chauvin	2015-03-03
124		2015-03-03-07:30 UTC	Morning direct sunlight appartently hit both water containers and increased the water temperature by about 1.0°C Need to fix the influence of direct sunlight	Nicolas Chauvin	2015-03-03

128		2015-03-05-13:30 UTC	Cell#2: problem reappears with the voltage measurement in the red channel. The input power is correct though.	Nicolas Chauvin	2015-03-05
129		2015-03-05-17:00 UTC	Cell#2: the problem with the red channel voltage is probably a bad connection with the measurement wire inside the cell. There is no voltage drops on the connections outside the cell and the voltage coming into the HUGnet board is not correct. Unfortunaterly, we need to rely on the power suppy measurement values, but they are not logged.	Nicolas Chauvin	2015-03-05
130		2015-03-06-18:30 UTC	Cell#2: Fix the voltage measurement issue with the red channel by measuring the voltage with the input power wire instead of the measurement wire going into the cell. Now the power measured on the red channel is correct and slighly over estimated by about 50 to 100 mW (power through the input current wire).	Nicolas Chauvin	2015-03-06

135		2015-03-11-10:35 UTC	Cell#2: instalbilities on the red channel wire. Red channel wire resistance has variation => bad connection or oxydation problem	Nicolas Chauvin	2015-03-11
136		2015-03-11-15:30 UTC	Cell#2: big resistor wire spike on red channel then back to insable value close to the 20W input power	Nicolas Chauvin	2015-03-11
137		2015-03-11-17:15 UTC	Cell#2: current on red channel dropped to zero at 17:15 then come back life at 17:22 then dropped again to zero at 17:28. The nichrome wire is broken or the wire connection is brocken due to oxydation with steam.	Nicolas Chauvin	2015-03-11
138		2015-03-11-18:15 UTC	Cell#2: open the insulation cabinet to investigate the wire problem.	Nicolas Chauvin	2015-03-11

150		2015-03-21-15:00 UTC	The cells went out of synch from 2015-03-21-15:00 to 2015-03-22-04:00 due to larger evaporation of water in cell#1. The water level went below the head of the cell in cell#1 earlier than in cell#2. This induced an inflection in the water temperature at 2015-03-21-14:30 for cell#1 and at 2015-03-22-20:00 for cell#2. This increased the temperature difference until 2015-03-22-04:00 when the water level was completely below the cell head on both cells. The cells went back in synch bwteen 2015-03-22-04:00 and 2015-03-22-16:00 However, a higher water temperature in cell#1 for about 12 hours induced a significant lower amount of water in cell#1 compare to cell#2. Cell#1 temperature started to decrease at 2015-03-22-16:00 due to lack of water and too much heat being dissipated through convection with air. Cells were out of synch again between 2015-03-22-16:00 and 2015-03-23-07:00, until the water container were refilled.	Nicolas Chauvin	2015-03-23

155		2015-03-24-17:38 UTC	Cell#1: problem with the power supply. The red channel of the power supply stopped and entered into "Sense Trip" mode.	Nicolas Chauvin	2015-03-25
156		2015-03-25-07:15 UTC	Cell#2: stop power on both channel to cool down the water to match cell#1 running on a single channel for now.	Nicolas Chauvin	2015-03-25
157		2015-03-25-09:30 UTC	Cell#2: put power back only on blue channel: 22.5 W input to match cell#1	Nicolas Chauvin	2015-03-25
158		2015-03-26-08:30 UTC	The cells are back in synch with 22.6 W input powe. It took about 24h to settle back to a stable temperature. We will test 4 - 5 more hours at 22.6 W to validate that the cells stay in synch.	Nicolas Chauvin	2015-03-26
159		2015-03-26-12:45 UTC	Increase input power to 25W on each channel for both cells (50W total per cell). The 2 cells are perfectly in synch.	Nicolas Chauvin	2015-03-26

164		2015-03-31-07:40 UTC	Cell#1: TC_5 measuring the cabinet air temperature is apparently not correctly attached anymore. The tape fixing it does not like the high humidity hot air. Will fix this next time the cabinet will be open to refill water.	Nicolas Chauvin	2015-03-31
165		2015-04-01-06:50 UTC	Refill water in container for both cells and fine tune input powers. Better fix the TC_5 in cell#1. It had fallen on the floor of the cabinet.	Nicolas Chauvin	2015-04-01
166		2015-04-01-06:50 UTC	Cell#2: open the cabinet several times for a photo shoot session. Water temperature has dropped a little.	Nicolas Chauvin	2015-04-01
167		2015-04-02-06:35 UTC	Refill water in container for both cells and fine tune input powers.	Nicolas Chauvin	2015-04-03
168		2015-04-03-13:00 UTC	Upgrade both cells with automatic water level system (communicating vessels with external water container). Both cell's vase will always have the same water level now.	Nicolas Chauvin	2015-04-03
169		2015-04-03-13:20 UTC	Fine tune input powers. (27.5W per wire, 55W total).	Nicolas Chauvin	2015-04-03
170		2015-04-03-16:40 UTC	Better insulation of cabinet gasket at wire passthrough locations for both cells.	Nicolas Chauvin	2015-04-03
171		2015-04-04-14:45 UTC	The automatic water level system did not work as planned. With heat, the water tubes became very soft and the one in cell#1 got out of the water vase resulting in a mini flood in the lab. It aslo emptied the external water reservoir much faster than expected resulting to a lack of water in cell#2. Now, the water tubes have been fixed with tape. Hopefully it will work correctly now. This also explains the lack of good TC_4 sychnization between cell#1 and cell#2 over the last 24 hours.	Nicolas Chauvin	2015-04-04
172		2015-04-04-17:00 UTC	Fine tune input powers. (27.5W per wire, 55W total).	Nicolas Chauvin	2015-04-04
173		2015-04-05-05:55 UTC	Cell#1: TC_5 measuring the cabinet air temperature fell down again. Will fix this next time the cabinet will be open.	Nicolas Chauvin	2015-04-05
174		2015-04-05-17:10 UTC	Refill the external water reservoir. Water evaporation in the vases is faster than expected. The automatic water level system will need an external reservoir with a larger surface. Overpressure inside both cabinets has apparently also built up, preventing the communicating vessels from balancing the water level between the vases and the external reservoir correctly. A small tube has been placed on both water cabinet to balance the pressure inside and outside the cabinets.	Nicolas Chauvin	2015-04-06
175		2015-04-05-18:00 UTC	Cell#2: open the cabinet to fix a problem with the communicating vessel. The water was not flowing correctly.	Nicolas Chauvin	2015-04-06

178		2015-04-06-16:20 UTC	Cell#1: fix problem with the communicating vessel Apparently air bubbles in the system prevent the water level to be well balanced.	Nicolas Chauvin	2015-04-07
179		2015-04-07-06:20 UTC	Cell#2: fix small problem with the communicating vessel.	Nicolas Chauvin	2015-04-07
180		2015-04-07-06:30 UTC	Fine tune input powers. (27.5W per wire, 55W total).	Nicolas Chauvin	2015-04-07
181		2015-04-07-08:45 UTC	The automatic water level system is still not working as expected. It seems to work with batch of water. The tubes used might have a too small diameter which might prevent the correct equilibrium of pressure. Each time a batch a fresh water is added to the cell's vase, the water temperature is reduced by at least 1.0°C.	Nicolas Chauvin	2015-04-07
182		2015-04-07-16:25 UTC	Turn the power off on both cells and let them cool down.	Nicolas Chauvin	2015-04-08
183		2015-04-08-11:00 UTC	Open cabinets and empty water from cell#2 vase	Nicolas Chauvin	2015-04-08
184		2015-04-08-11:15 UTC	Cell#2: open cell to replace Nichrome wires with Celani active wires.	Nicolas Chauvin	2015-04-08

186		2015-04-08-18:15 UTC	Cell#2: evacuate the cell and fill it with 3.6 bars of hydrogen to prepare the wire loading process and test for leaks.	Nicolas Chauvin	2015-04-08
187		2015-04-08-18:35 UTC	Cell#2: turn on the power with 1.0V to measure the resistivity of both wires. And turn off the power.	Nicolas Chauvin	2015-04-08
188		2015-04-09-14:45 UTC	Cell#2: Testing power supply control sequence for hydrogen loading process. Blue channel: R0 = 18.59 ohm Red channel: R0 = 17.65 ohm	Nicolas Chauvin	2015-04-09
189		2015-04-09-15:40 UTC	Cell#2: Start hydrogen loading sequence: 180 minutes at 2x 18.2W, then 60 minutes at 2x 3.5W and repeat during 24 hours.	Nicolas Chauvin	2015-04-09
190		2015-04-11-14:25 UTC	Set hydrogen pressure to 1.36 bars (at 27.3°C) in both cells. Set vacuum pressure to 3.0 mbars.	Nicolas Chauvin	2015-04-11
191		2015-04-11-15:30 UTC	Close the cabinets, install the communicating vessels and seal the cabinets with tape.	Nicolas Chauvin	2015-04-11
192		2015-04-11-16:00 UTC	Start Experiment Run ================ Set input power to 15W on each channel for both cells (30W total per cell). Cell#1: passive cell using Nichrome wires (reference). Cell#2: active cell using Celani wires (LENR cell).	Nicolas Chauvin	2015-04-11

195		2015-04-18-07:20 UTC	Refill the external water tank. There was still water in both cell's wave and above the top flange. However the water in cell#2 is at a lower level.	Nicolas Chauvin	2015-04-20
196		2015-04-20-12:00 UTC	Cell#2: the water level is low and close to the top of the flange. The bolts and Swagelok fittings are outside the water which introduce error in the water temperature measurements. The communicating vessel refilling water in cell#2 is apparently not working correctly. It needs to be fixed before any conclusion can be claimed.	Nicolas Chauvin	2015-04-20
197		2015-04-27-12:00 UTC	Cell#2: open the insulation container and fix the communicating vessel tube. Exchange the tube with a thicker one.	Nicolas Chauvin	2015-04-27
198		2015-04-27-12:30 UTC	Refill the external water tank. Both cells have now the same water level again.	Nicolas Chauvin	2015-05-18
199		2015-05-06-11:27 UTC	Turn the power off on both cells and let them cool down. Cell#1 communication vessel will also need to be changed. And after discussion with Celani, the experiment need to be updated with 1/3 Hydrogen + 2/3 Argon to increase the inside temperature. A software to drive the 4 power supplies is also being written to be able to increase the input power for short periods of time (typ. 15 - 30 minutes) to maximize the internal temperature.	Nicolas Chauvin	2015-05-18
200		2015-05-16-15:45 UTC	Cell#1: replace hydrogen with 0.9 bar of gas mixture: 1/3 hydrgen + 2/3 argon to increase the internal temperature.	Nicolas Chauvin	2015-05-18
