The purpose of this test is to check if some anomalous ( a, b ,g ) radiations can be detected near the Cold Fusion Reactor ( CFR ) v4.0. For the measurement, I have used a Geiger counter, the Gamma-Scout^® handled radiation detector.The Gamma-Scout^® reliably measures alpha, beta, gamma and x-radiation, it is the latest development in handheld Geiger counters, designed specifically for homeland security.

The Gamma-Scout^® handled radiation detector has been placed just in front of the CFR v4.0 and a digital clock allows to record the time Vs the logged datas. The detector has been tuned so as to detect all the radiation spectrum ( Alpha, Beta, Gamma, and X-radiation ).

The CFR v4.0 is powered with a DC voltage through a bridge rectifier connected through a variable transformer ( Variac ) to the 220V AC power grid line. The voltage input has been measured with a digital oscilloscope Fluke 123 with a Shielded Test Lead STL 120 ( 1:1, 1 Mohms/225 pF ). The current input has been measured with a current clamp CIE Model CA-60A ( Accuracy DC Amps ±1.5%, AC Amps±2% (40Hz-2kHz), AC Amps±4%(2kHz-10kHz), AC Amps±6%(10kHz-20kHz) ). The Power Meter C1 X3 is connected at the input of the variac and to the Power grid. The temperature has been measured with a type "K" temp probe ( NiCrNi ) connected on a VC506 digital multimeter ( -20°C to +1200 °C with an accuracy of +/- 3% ). ( see the photo above ).

Electrolyte solution : 2000 mL of K2CO3 ( 0.2 M ),
ELECTRICAL INPUT : AVG POWER = 1345.8 Watts, Voltage : 256 Volts
RUNNING TIME = 177.6 sec
ELECTRICAL ENERGY INPUT = 239014 Joules
CFR OUTPUT : Start Temp = 75°C - Final Temp = 96°C
Evaporated water = 100 mL, Delta T = 21°C
CFR ENERGY OUTPUT = 401560 Joules
Pwr OUT = 2261 Watts - Power Gain = 915.3 Watts

COP = Output/Input = 1.68

TESTS RESULTS : The radiations have been recorded by the Gamma-Scout^® during the test run ( between 09h43 to 09h46 ) and then uploaded to a PC computer. As you may observe in the recorded datas, no significant increase in radiations have been detected during the test run ( see the results below ).

Above :The pure Tungsten cathode is subject to the Hydrogen Embrittlement Cracking ( HEC ) effect.
The presence of atomic hydrogen in the tungsten at very high temperature produces a lot of longitudinal fractures in the cathode.
The cathode disintegrates as time the tests runs and a fine Tungsten powder settles in the bottom of the Dewar vessel ( see below ).
