Straight-in cathode ray tube This product demonstrates the phenomenon that the cathode ray tube moves in a straight line and can be blocked by metal. The product consists of blister, metal baffle, bracket, cathode, anode, bakelite seat, etc. Demonstration of straight into the cathode ray tube is best carried out in a dark room. During the demonstration, A2 emits cathode rays, and a shadow with the same shape as the metal baffle appear on the glass wall of the large-end screen of the ray tube. Bright yellow-green fluorescence appeared on the glaze around the shadow.it can be explained that the cathode ray moves along a straight line, and its ability to penetrate the metal sheet is very weak. Scope of application: Teachers teach in laboratory classrooms to increase students' interest in physics and electricity Product name: Straight into the cathode ray tube Product size: 255 x 200 mm/10.03 x 7.87 in Product weight: 365g Note: 1. Vacuum glass products are fragile. Pay attention to protect the bubble shell to prevent vacuum failure. 2. The use time should not be too long, which is easy to affect the accuracy of the instrument. 3. The instrument shall be placed flat and stable and stored in a cool, ventilated and dry place. conditions: 1. The relative humidity does not exceed 80%. 2. Temperature -40 - 101°C. Precautions: 1. Vacuum glass products, handle with care, pay attention to protect the bulb to prevent gas failure. 2. When connecting electrodes, do not use excessive force to avoid damage to the instrument. 3. Pay attention to the wiring according to the wiring diagram, proofread the power supply voltage, and check the error to prove it.
