Some technicians have asked me to put before the description of the principle of operation of the instrument, a simple design of his electric circuit. I do additionally present that the good operation of the instrument, he is tightly tied to the stability of the voltages and of the current of feeding, and he in peculiar way needs to hold stable the temperature of the whole, since this is last that you assure the high resolution that in succession will need for see smallest details of the wave. For complete, he is necessary that the phosphori issue an amount of light strictly invariable in the time
the principle of operation of the instrument is based on the occurrence that, the fundamental constants, velocity of the light, constant dielectric and magnetic permeability, they change in continuation. These I has replaced with resistance, inductance and capacity. This substitution realize necessary for be able to resolve the puzzle of the reading of the graphics that the instrument produces. By an attentive analysis of the electric field and of the gravitational field, I have noticed that in presence of a gravitational wave, the constant dielectric of the space changes considerably; this change causes a change of the electrical charge of the electron and of the proton. the change of the electrical charge of the electron brings to a change of the energy with which the electron strikes the fluorescent screen of the vacuum tube, and also if all the instruments places to control of the voltages of acceleration of the anode and to the current issued of the cathode, they stay invariable, I record a change of resistence on the photoresistor. I have employed more of two years for arrive at to understand so that the resistance of the photoresistor has changes as high. In occasion of the collapse of the 1994, the value of the resistance, he exceeded the hundred per cent, (among maximum and minimum), the that he coincides to a change of the constant dielectric of about the forty per cent. He seem impossible that a fact of the kind happens, but if you will build and will put point this type of instrument, you will go meet to surprises almost inexplicable, you will see change a resistance that according to the laws of the electrology constant should stay. And you will record the same graphics that I register. I in these four years have built tens of sensors of different form, that they are always founded on the measure of a light source by part of a photoresistor; but only some they have functioned, best part must have threw away them. At the moment only three, more than the main, they function perfectly. When I will describe the put on to point of one of these, I will indicate you which obstacles will overcome.
Power supply of the instrument.For the building of the power supply that now to prepare oneself to describe I has used integrate of the type LM317 positive, and LM337 negative. So that I have used this type of integrate: for two reasons; the first because I am adjustable regulators, like second point, because they have a low coefficient thermic and a good stability of voltage a long time term. If you afterward want to use other models to higher stability, you are free of do it. The stabilizers have been by me select of djustable type because in succession do of the calibration to the instrument, and stabilize the current issued from the cathode of the vacuum tube, it results essential use adjustable stabilizers. In the design below brought again the diagram of the power supply is seen very well which he could function is with accumulators, that with transformer and rectifiers. he is sufficient that the positive voltage is inclusive between +25 and +40 volt, while the negative voltage is inclusive between -12 and -20 volt. I with these two voltages obtain: +18 volt for feed the positive of the differential amplifier that stabilizes the current issued by the cathode, +12.6 volt that furnishes the voltage of acceleration of the anode of the vacuum tube. Additionally I obtain from -1.6 to -2.0 adjustable volt for the feeding of the cathode of the vacuum tube; -8.0 volt for feed the negative of the differential amplifier. Additionally I take the voltages from +12.6 volt to -8.0 volt, for feed the bridge of Wheatstone to 20.6 volt where you locate the photoresistor. He follows electric diagram.
All the values of the resistances, they must be at one per cent and to low coefficient thermic. The four capacitors by 10 microfarad are to the tantalum. The two capacitors by .1 microfarad are in polyester. All the other capacitors, they are of the type electrolytic with a voltage of work of 50 volt. It is necessary that the variable resistance by 1 kiloohm used for the adjustment of the voltage of feeding of the cathode, ( -1.6 -2.0), it is of type multiturns, or yet good if he is digital, because he allows a more accurate adjustment of this voltage. In the description of the differential amplifier, he could be seen in detail, like a resistance is built digital variable. He is necessary apply heatsinks at four stabilizers, LM317 and LM 337, to form of L, of sizes ( 3 centimeters for 6 centimeters thickness 2 millimetre ) of plate of aluminum, for sustain them most possible to temperature background.
Instrument with photoresistors.
The most important part of the instrument, he is the construction of the sensor, that is composed by a vacuum tube type ( FUTABA 6-LT-01 8D ) with glued on the glass that it looks at the issued light by the phosphori, and by the four at five photoresistors to the sulphide of cadmium. I glue four or five of them, in way that during the operation of the instrument, one cans choose a couple of these photoresistors, that they produce each, a graphic perfectly similar to the other. (you see diagram test13.htm), where three photoresistors produces each a diagram perfectly equal to the others two. IMPORTANT NOTE to hold in mind: when the all will be functioning, the instrument won't be more fireless; if you will do of the modifications, you hold present that you will be obliged to do to alight instrument. The instrument for become operative he has need of at least 12 months of continual lighting for have formatted, this kind of memory acquires in manner it always better, with the pass of the time. He for this reason is necessary that it doesn't never come fireless, he otherwise loses itself this type of memorization. He could happen that he for some minute comes broken off the feeding, but you do well attention that the break is briefest possible, you otherwise will do again the formatting again, the that means lose other months of time. The experience that you will do will be of fundamental importance. The principle of operation is easy, but do it function all he is an other thing.The main components are two, the vacuum tube and the photoresistors. See the two images under brings again.
The display that I here show is the FUTABA 9-LT-01 8D. While he that employed in the sensor is the FUTABA 6-LT-01 8D. and he has three digits in less, that is 6 rather than 9.
Before gluing on the glass of the vacuum bube the photoresistors, he is necessary screen the side of the vacuum tube from where the light originates, with two black and adhesive strip, in way to produce a bright slit of approximately 1.5 millimetre of width. you see figure under brought again.
Then they are glued one to one, all the photoresistors on this slit, with glue to the transparent cyanide, in way to constitute an unique body with the glass. he is necessary that the grid of the photoresistor is perpendicular to the light slit. you see figure above.
The two photo under bring again, they represent the anterior and back part of a vacuum tube similar to the futaba 6-LT-01 8D, he is the vacuum tube FUTABA 5-LT-02 9F. This second vacuum tube he has the same electrical parameters of the precedent. He has that is the same electric voltage of acceleration and the same voltage of feeding of the filament.
